• Diabetes drug improves memory, study suggests - Science Daily, 11/21/12 - "treatment with the anti-insulin-resistance drug rosiglitazone enhanced learning and memory as well as normalized insulin resistance. The scientists believe that the drug produced the response by reducing the negative influence of Alzheimer's on the behavior of a key brain-signaling molecule" - Note:  Rosiglitazone is the one that they say increases the risk of heart disease.  Pioglitazone is in the same class of drugs but they claim that increases the chances of bladder cancer.  Personally I don't have diabetes but I take low dose metformin and pioglitazone.  See my Insulin and Aging page.  See pioglitazone at OffshoreRX.com.
• Pioglitazone Is Associated With Risk for Bladder Cancer - Medscape, 8/7/12 - "Ever use of pioglitazone was associated with 83% higher risk for bladder cancer — a significant increase — compared with never users. The bladder cancer rate increased significantly with duration of pioglitazone use, with the highest rates in patients who were exposed for >2 years, and in patients whose cumulative dose exceeded 28,000 mg. Notably, no excess risk for bladder cancer was observed for patients who received rosiglitazone (Avandia)"
• Effect of pioglitazone on testosterone in eugonadal men with type 2 diabetes mellitus: A randomized double blind placebo-controlled study - Clin Endocrinol (Oxf). 2012 Jul 20 - "randomly assigned to receive pioglitazone 30 mg per day or placebo along with existing glimepiride and metformin therapy ... As compared to placebo, six months of pioglitazone therapy in patients with T2DM resulted in significant reduction in mean total testosterone level (16.1 to 14.9 vs 17.1 to 17.0 nmol/L; p = 0.031), calculated free testosterone (p = 0.001) and bioavailable testosterone (p = 0.000) despite significant increase in sex hormone binding globulin (p = 0.000). Plasma androstenedione (∆(4) ) level increased (1.5 to 1.9 ng/ml; p = 0.051) following pioglitazone therapy"
• Brain insulin resistance contributes to cognitive decline in Alzheimer's disease - Science Daily, 3/23/12 - "This is the first study to directly demonstrate that insulin resistance occurs in the brains of people with Alzheimer's disease ... Our research clearly shows that the brain's ability to respond to insulin, which is important for normal brain function, is going offline at some point ... We believe that brain insulin resistance may be an important contributor to the cognitive decline associated with Alzheimer's disease ... The risk of developing Alzheimer's disease is increased by 50 percent in people with diabetes ... insulin resistance of the brain occurs in Alzheimer's disease independent of whether someone has diabetes ... The investigators used samples of postmortem brain tissue from non-diabetics who had died with Alzheimer's disease, stimulated the tissue with insulin, and measured how much the insulin activated various proteins in the insulin-signaling pathways ... three insulin-sensitizing medicines are already approved by the FDA for treatment of diabetes. These drugs readily cross the blood-brain barrier and may have therapeutic potential to correct insulin resistance in Alzheimer's disease and MCI" - Note:  I suspected this for a long time.  It doesn't say what those three drugs are but I'm guessing metformin and Actos are two of them.  I don't have diabetes but I take low doses of both.  My doc says I'm crazy.
• Pioglitazone: A Key Component for Type 2 Diabetes Therapy - Medscape, 10/5/11 - "Even in patients who do not already have known CV disease there is an increasingly strong case developing in favour of using the combination of metformin, pioglitazone and a GLP-1 agonist in the modern management of type 2 diabetes.[42] This case is argued by Professor Ralph DeFronzo who, in print[42] as well as in a webcast,[43] describes an 'ominous octet' of factors combining in the pathophysiology of type 2 diabetes (figure 4). With regard to these eight factors he points out that sulphonylureas only improve insulin secretion and that even this effect is transient. By contrast, GLP-1 agonists impact on five members of the ominous octet, pioglitazone on four and metformin on two, and that the effects of these agents are complementary and some at least are sustained. As a potent insulin sensitiser, pioglitazone reduces hepatic glucose output and increases glucose uptake in muscle. It improves and preserves pancreatic beta-cell function and therefore insulin secretion and it is also a potent inhibitor of lipolysis. At the level of the liver, metformin is a potent insulin sensitiser reducing hepatic gluconeogenesis and in muscle it provides an additive effect to pioglitazone in promoting glucose uptake. GLP-1 analogues increase the incretin effect, increasing insulin secretion, reducing glucagon secretion and hepatic glucose output. Finally GLP-1 agonists act on the brain reducing appetite and promoting weight loss. DeFronzo[42,43] reminds us that even at the stage of impaired glucose tolerance, individuals have lost >80% of their beta-cell function. Therefore he argues that the modern paradigm for the management of type 2 diabetes would involve intensive management at the earliest stages using metformin, pioglitazone and GLP-1 agonists in combination with a view to achieving a target HbA1C <6%.[42,43] It is worth noting in particular that the combination of these agents does not require expensive home glucose monitoring and these agents are not associated with a risk of hypoglycaemia"
• Diabetes Drug Actos May Raise Risk for Bladder Cancer: FDA - US News and World Report - U.S. News & World Report, 6/16/11 - "In one study involving more than 193,000 patients with diabetes, patients taking Actos were on the drug for an average of two years, the FDA said. "Compared to never being exposed to pioglitazone, a duration of pioglitazone therapy longer than 12 months was associated with a 40 percent increase in risk [for bladder cancer]"
• Diabetes drug Actos linked to possible cancer risk - The Boston Globe, 6/10/11 - "The study found about a 22 percent higher risk of bladder cancer in those taking Actos compared with diabetics taking other drugs"
• Pioglitazone to Prevent Progression to Diabetes: Abstract and Introduction - Medscape,5/25/11 - "More placebo recipients (17%) than pioglitazone recipients (5%) progressed to diabetes. Mean glycosylated hemoglobin (HbA1c) levels rose by 0.2% in the placebo group and remained unchanged in the pioglitazone group"
• System in brain -- target of class of diabetes drugs -- linked to weight gain - Science Daily. 5/1/11 - "PPAR-γ is the target of a class of diabetes drugs called TZDs (thiazolidinediones). This class of drugs reduces blood glucose levels but also causes considerable weight gain ... Seeley and his team set out to determine whether or not the brain's PPAR-γ system was responsible for the weight gain associated with TZDs ... by giving TZD drugs in the same manner that people take them, rats gained weight. This was because the drugs activated PPAR-γ in the brain. Thus, weight gain associated with this class of drugs may not be a result of action of PPAR-γ in fat as had been previously thought, but rather a result of a change in activity in parts of the brain known to regulate appetite ... If you artificially turn on PPAR-γ, you can increase food intake in rats ... If you block these receptors in animals on high-fat diets that make animals obese, animals gain less weight ... In the past, says Seeley, people thought that the production of more fat cells in response to TZD drugs was the cause of the resulting weight gain, but he adds, "Just having more fat cells is not enough to make animals or people fatter. Rather you have to eat more calories than you burn and that is exactly what happens when you turn on the brain PPAR-γ system"
• Obesity and Fatty Liver disease - MedicineNet.com - "Doctors also are using medications to treat non alcoholic fatty liver disease. For example, insulin-sensitizing agents, such as the thiazolidinediones, pioglitazone (Actos) and rosiglitazone (Avandia), and metformin (Glucophage) not only help to control blood glucose in patients with diabetes, but they also improve enzyme levels in patients with non alcoholic fatty liver disease"
• Pioglitazone Shows Promise for Oral Cancer Prevention - Medscape, 3/23/11 - "In a phase 2 clinical trial, the thiazolidinedione pioglitazone partially or completely eliminated two thirds of leukoplakia lesions, which can sometimes become cancerous ... Pioglitazone (Actos, Takeda Pharmaceuticals) "works pretty well — better than anything we've seen before ...Leukoplakia lesions, which are usually caused by irritation, appear on the tongue or sometimes on the insides of the cheek. About 17% of the lesions become invasive cancer, and no treatment has been shown to reliably prevent this ... The researchers randomly divided these patients so that 22 patients received pioglitazone 45 mg daily for 12 weeks and 22 patients served as a comparison group ...15 of the 22 patients in the pioglitazone group had a clinical and/or histologic response; they did not detect any change in the comparison group ... In the pioglitazone group, the lesions completely disappeared in 3 patients and partially disappeared in 12 patients, the epithelium completely returned to normal in 1 patient, and the dysplasia or hyperplasia reverted from advanced to early, or from early to normal, in 6 patients ... Because it is a diabetes drug, researchers checked the subjects' glucose levels, but they found no change, apparently because pioglitazone only affects glucose in diabetics"
• Drug prevents Type 2 diabetes in majority of high-risk individuals - Science Daily, 3/23/11 - "A pill taken once a day in the morning prevented type 2 diabetes in more than 70 percent of individuals whose obesity, ethnicity and other markers put them at highest risk for the disease ... The team also noted a 31 percent decrease in the rate of thickening of the carotid artery, the major vessel that supplies blood to the brain ... The 72 percent reduction is the largest decrease in the conversion rate of pre-diabetes to diabetes that has ever been demonstrated by any intervention, be it diet, exercise or medication ... pioglitazone, which is marketed as Actos® ... It is the most efficacious method we have studied to date to delay or prevent the onset of type 2 diabetes ... This particular medication does two things -- improves insulin resistance and improves beta cell function, which are the two core defects of diabetes" - Note:  Like I've said before, my doc says I'm crazy but I've been taking pioglitazone for anti-aging for some time.  Something that’s discerning is when someone asks why I look young and I mention various things and they disagree with it all of it.  Anyway see pioglitazone at OffshoreRX.com.
• PERISCOPE Analysis Highlights TZD Lipid Effects - Medscape, 1/10/11 - "In that randomized comparison of the thiazolidinedione (TZD) vs glimepiride(Amaryl, Sanofi-Aventis) in patients with diabetes [2], those taking the TZD saw significantly less coronary disease progression as assessed with intravascular ultrasound (IVUS) over 18 months compared with those taking the other drug, a sulfonylurea. They also benefited with steeper declines in fasting insulin and blood glucose levels, glycated hemoglobin (HbA1C), C-reactive protein (CRP), and triglycerides as well as improved HDL-cholesterol levels ... the post hoc analysis "ties nicely" with the 2006 CHICAGOstudy, in which elevations in HDL were the most important predictor of reduced progression of carotid intima-media thickness"
• Molecular 'switch' contributes to cellular aging process: Discovery suggests new treatments for metabolic diseases - Science Daily, 11/30/10 - "in older animals SMRT acts like a "switch," turning off the protective cellular activities of proteins known as peroxisome proliferator-activated receptors (PPARs). PPARs help regulate genes that promote fat burning to maintain lipid (blood fat) balance and reduce oxidative stress. The researchers were able to reduce the negative effects of oxidative stress by giving antioxidants or drugs known to turn the protective activities of PPARs back on ... PPAR drugs have been used to increase insulin sensitivity and lower blood lipid levels ... we believe SMRT is one of the key players that causes age-dependent decline in mitochondrial function by blocking PPAR activity, and we've found a way to boost the body's ability to better handle metabolic and oxidative stress" - Note: There are several PARR receptor activators such as the blood pressure drug telmisartan and the diabetes medication Actos (some doctors have criticized me for years for taking it for anti-aging).  I've started a webpage on PPARs.  When I get a chance I'll search my site and put the articles on it.
• Study compares risk with 2 diabetes drugs - Science Daily, 8/24/10 - "risks of heart disease events and death were no different between patients who took the diabetes drugs rosiglitazone or pioglitazone. In this analysis, approximately 4 percent of patients taking either drug -- sold as Avandia and Actos -- suffered a heart attack, heart failure, both or died over a 33-month period ... Besides its findings that rosiglitazone and pioglitazone have comparable risks, what distinguishes this latest study from other claims-based analyses is its analysis of death records, which include out-of-hospital deaths ... study also followed patients for a longer period of time than some of the earlier research" - So the two drugs have equal risks but what's confusing is how does that 4% risk compare to a placebo?
• Pioglitazone attenuates prostatic enlargement in diet-induced insulin-resistant rats by altering lipid distribution and hyperinsulinemia - Br J Pharmacol. 2010 Aug 19 - "Increased incidence of benign prostatic hyperplasia among insulin-resistant individuals suggest a role for hyperinsulinemia in prostatic enlargement ... High fat diet led to the accumulation of fat in non-adipose tissues, insulin resistance, compensatory hyperinsulinemia and prostatic enlargement in rats. Pioglitazone treatment altered fat distribution, improved insulin-sensitivity and normalized lipid and insulin level in rats on the high-fat diet. The improved metabolic parameters led to decreased cellular proliferation and increased apoptosis in the prostate gland. High-fat diet feeding and pioglitazone treatment did not change plasma testosterone levels. However, significant prostatic atrophy was observed in castrated, rats irrespective of dietary intervention"
• Vitamin E may be new boon for liver disease - MSNBC, 4/28/10 - "In the study published online in the New England Journal of Medicine, 247 adults with advanced fatty liver disease were randomly assigned to take a high dose of vitamin E (800 international units), the diabetes drug Actos or dummy pills for nearly two years ... Biopsies before and after treatment showed that liver function improved in 43 percent of those in the vitamin E group compared with 19 percent in the placebo group ... participants on the diabetes drug Actos also improved, but to a lesser degree and with a drawback: gaining 10 pounds on average, which remained even after they stopped taking the drug" - See Jarrow FamilE (contains all eight members of the vitamin E family) at iHerb.
• Pioglitazone improves endothelium-dependent vasodilation in hypertensive patients with impaired glucose tolerance in part through a decrease in oxidative stress - Atherosclerosis. 2010 Jan 4 - "Pioglitazone improved endothelial function in hypertensive patients with IGT through an increase in nitric oxide bioavailability by, in part, a decrease in oxidative stress" - Pioglitazone is one that I take to help prevent diabetes and for anti-aging.
• Metformin vs. Sulfonylureas for Diabetes - WebMD, 12/4/09 - "Researchers reported that diabetes patients who used sulfonylureas had a higher risk of death from all causes and a higher risk of heart failure than diabetes patients who used the most widely prescribed diabetes drug, metformin ... Compared with metformin, also known as Glucophage, single-drug treatment with first- and second-generation sulfonylureas was associated with up to a 61% increased risk for death. Users of second-generation sulfonylureas had up to a 30% higher risk for congestive heart failure ... Patients treated with Actos or Avandia did not appear to have a greater risk for heart attacks than those treated with metformin"
• Diabetes Drug Shows Promise In Fighting Lethal Cancer Complication - Science Daily, 9/24/09 - "in an animal study, a diabetes drug that promotes insulin sensitivity slowed the progression of muscle wasting and fat loss, the main consequences of a syndrome called cachexia ... Research suggests that cachexia is responsible for between one-fifth and one-third of all cancer deaths ... These data provide evidence that in mice with colon cancer tumors, insulin resistance may be involved in the development of cachexia rather than occur as a result of cachexia ... Within eight days, the mice with cancer receiving the rosiglitazone showed more sensitivity to insulin than did the mice with tumors that received no medication. The insulin sensitivity of the medicated mice matched that of mice without tumors ... In addition to stopping fat and muscle loss, the rosiglitazone also dramatically reduced two biological markers present when proteins break down, particularly in muscles, and a third marker that indicates cells are eating their own amino acids in an attempt to survive" - Note:  I don't know why they did this study with rosiglitazone.  That's the one that may be connected to heart disease.  Pioglitazone is the same class of drug and is not connected to heart disease.  I take it for anti-aging also.  See my Insulin and Aging page.

• Efficacy and safety of therapy with metformin plus pioglitazone in the treatment of patients with type 2 diabetes: a double-blind, placebo-controlled, clinical trial - Curr Med Res Opin. 2009 Mar 23 - "Mean HbA(1c) was reduced by 0.67% in patients receiving pioglitazone plus metformin versus an increase of 0.25% in those receiving metformin alone (p < 0.0001). After 8 weeks' treatment and until the end of the study, HbA(1c) was significantly lower with pioglitazone plus metformin and more patients in this group achieved an HbA(1c) < 6.5% (38.6% vs. 8.1%; p < 0.0001). FBG was also reduced by a significantly greater amount in patients receiving pioglitazone plus metformin compared with metformin monotherapy (-20.5 vs. 1.9 mg/dl; p < 0.0001). Combination therapy was associated with significantly increased HDL-cholesterol, total cholesterol, and adiponectin, and significantly decreased levels of fasting insulin, free fatty acids, and homeostasis model assessment insulin resistance (HOMA-R) compared with metformin monotherapy" - See pioglitazone at OffshoreRX.com.
• Insulin May Protect Mind, Memory - WebMD, 2/2/09 - "lower insulin levels were enhanced by adding Avandia, which increases the body's sensitivity to insulin. Study authors say the discovery that diabetes drugs shield nerve junctions in the brain from memory loss offers new hope for fighting the disease" - Note:  Avandia is the one with increased heart disease.  I've been taking Actos (pioglitazone) for prevention.  See pioglitazone at OffshoreRX.com.
• Pioglitazone vs glimepiride: Differential effects on vascular endothelial function in patients with type 2 diabetes - Atherosclerosis. 2008 Dec 6 - "In patients with type 2 diabetes already on metformin, addition of pioglitazone as compared to glimepiride, improved endothelial function despite similar glycemic control. The improvement in endothelial function was mainly due to a reduction in insulin resistance"
• Rosiglitazone reverses memory decline and hippocampal glucocorticoid receptor down-regulation in an Alzheimer's disease mouse model - Biochem Biophys Res Commun. 2008 Dec 22 - "An early down-regulation of GR, not related to elevated plasma corticosterone levels, was found in different hippocampal subfields of the transgenic mice and this decrease was prevented by rosiglitazone. In parallel with behavioural studies, rosiglitazone also normalized GR levels in older animals. This effect may contribute to explain the attenuation of memory decline by PPARgamma activation in an AD mouse model" - Note:  That's another reason I take rosiglitazone's competitor, pioglitazone which has less chance of causing heart problems.
• Popular Class Of Diabetes Drugs Doubles Risk Of Fractures In Women - Science Daily, 12/10/08 - "We knew going into this study that there was an association between thiazolidinediones and fracture risk ... these agents double the risk of fractures in women with type 2 diabetes"

Rates of first hospitalization for congestive heart failure—a known side effect of TZDs—were 13% higher in the rosiglitazone group than in the pioglitazone group. In contrast to recent studies pointing to a risk of ischemic events with rosiglitazone, rates of MI and stroke were no different between the groups"

But the authors have previously attracted criticism for focusing on this one secondary end point when the primary end point of the study was not significant ... "Because there was some controversy about our secondary end point, we decided to apply the PROactive data to other definitions of MACE often used in major clinical trials to see whether the results still held irrespective of which components of the MACE end point were included. We found a consistent reduction in events with all definitions with pioglitazone. This shows that we haven't been scrabbling around for one end point that was positive and that whichever MACE end point we used, we would have gotten a similar result.""
• Why Certain Diabetes Drugs Appear To Lower Blood Pressure - Science Daily, 3/4/08 - "Drugs called thiazolidinediones (TDZs), which are used to treat type II diabetes, target and activate PPAR gamma. In addition to controlling blood sugar, these drugs also appear to lower blood pressure ... It appears that when PPAR gamma is activated it initiates a cascade of events that protect the blood vessel ... When we interfere with the PPAR gamma pathway, those protective mechanisms are eliminated and the blood vessel becomes dysfunctional" - I've read all the negative of thiazolidinediones (TDZs) and I still feel the good outweigh the bad.  I take Actos (pioglitazone HCl) to help prevent diabetes among other thing like I feel they will eventually show that it helps prevent advanced glycation end products, a major cause of aging.
• Comparative effects of rosiglitazone and pioglitazone on fasting and postprandial low-density lipoprotein size and subclasses in patients with Type 2 diabetes - Expert Opin Pharmacother. 2008 Feb;9(3):343-9 - "HbA1c, insulin sensitivity (as assessed by the homeostasis model assessment) and LDL size and subclasses did not differ before treatments. Rosiglitazone and pioglitazone resulted in a similar improvement in HbA1c and insulin sensitivity. Fasting total cholesterol increased more after rosiglitazone compared with pioglitazone (p = 0.04), whereas triglycerides decreased after pioglitazone and increased after rosiglitazone ... Pioglitazone was more effective than rosiglitazone in increasing larger LDL concentrations (in both fasting and postprandial status) as well as in reducing levels of atherogenic small, dense particles (in postprandial status only)"
• Clinical trials with thiazolidinediones in subjects with Type 2 diabetes--is pioglitazone any different from rosiglitazone? - Expert Opin Pharmacother. 2008 Feb;9(3):405-20 - "these agents have markedly different effects on lipids. Rosiglitazone increases total, low- and high-density lipoprotein (LDL and HDL) cholesterol, and triglycerides, whereas pioglitazone has no effect on total or LDL cholesterol, increases HDL cholesterol and decreases triglycerides. Both rosiglitazone and pioglitazone decrease inflammatory markers. Furthermore, both rosiglitazone and pioglitazone may cause a small decrease in blood pressure, improve endothelial function and reduce restenosis. Microalbuminuria is also reduced by both rosiglitazone and pioglitazone. Despite the improvements in surrogate end points, there is little clear evidence that either rosiglitazone or pioglitazone cause major improvements in cardiovascular outcomes. Thus, rosiglitazone has no effect or may even increase cardiovascular outcomes, whereas, in high-risk subjects, pioglitazone has a marginal ability to decrease cardiovascular outcomes"

• Pioglitazone induces regression and stabilization of coronary atherosclerotic plaques in patients with impaired glucose tolerance - Diabet Med. 2011 Sep 26 - "Compared with the control group, 6 months' treatment with pioglitazone significantly decreased coronary plaque burden (50.7 ± 11.1 vs. 64.1 ± 10.3%, P < 0.05), plaque area (6.22 ± 2.03 vs. 8.31 ± 4.29, P < 0.05), thin-cap fibroatheroma prevalence (11 vs. 22%, P < 0.05) and percentage of necrotic core area (16 ± 8 vs. 31 ± 7%, P < 0.05). Compared with the control group, serum high-sensitivity C-reactive protein and plasma endothelin-1 levels were significantly lower and adiponectin level significantly higher in patients in the pioglitazone group. Serum adiponectin level was negatively correlated with plasma endothelin-1 level and coronary plaque area (r = 0.739 and -0.431, respectively, both P < 0.05). Conclusions:  Pioglitazone may induce regression and stabilization of coronary atherosclerotic plaques. The mechanisms might involve inhibition of inflammation, increase in adiponectin level and improvement in endothelial function"
• Thiazolidenediones induce tumour-cell apoptosis through the Akt-GSK3β pathway - J Clin Pharm Ther. 2011 Mar 16 - "Prostate cancer is a major health threat for men. Thiazolidenediones (TZDs) are synthetic ligands of the peroxisome proliferator-activated receptor γ (PPARγ), and previous studies have shown that TZDs induce apoptosis of prostate cancer cells independently of PPARγ activation. However, the exact mechanism of these effects remains unknown ... The apoptosis-inducing effect of TZDs on prostate cancer cells involves the inhibition of Akt phosphorylation. Furthermore, TZDs induce inactivation of GSK3β, a multifunctional kinase that mediates essential events promoting prostate cancer development and acquisition of androgen independence. In addition, the GSK3β inhibitor lithium chloride sensitizes prostate cancer cells to TZDs cytotoxicity. What is new and Conclusion:  Our data suggest that modulation of Akt-GSK3β pathway is involved in the cell death pathway engaged by TZDs in prostate cancer cells. This reveals another possible mechanism of TZDs on apoptosis in prostate cancer. Inhibition of the Akt-GSK3β cascade may be a useful approach in prostate cancer" - Got that because I'm going to give a test on it in next weeks newsletter.  The point is that TZDs such as pioglitazone may help prevent or slow prostate cancer.
• Pioglitazone activates aortic telomerase and prevents stress-induced endothelial apoptosis - Atherosclerosis. 2011 Feb 17 - "Telomeres and associated proteins are regulators of cellular survival, regeneration and aging. PPAR-γ agonists may mediate vascular effects in addition to insulin sensitizing. We therefore examined whether pioglitazone regulates vascular telomere biology ... C57/Bl6 mice were randomized to treatment with pioglitazone (20mg/kg i.p. daily) or vehicle for 4 weeks (n=6-8 per group). Telomere repeat amplification protocols showed a 2-fold increase of aortic telomerase activity in the pioglitazone group. Telomere repeat-binding factor 2 protein and mRNA levels (236%+172% of vehicle) as well as phosphorylation of protein kinase Akt (479% of vehicle) were up-regulated. Western blots demonstrated reduced aortic expression of senescence markers p16, cell-cycle checkpoint kinase 2 and p53. These regulatory mechanisms were independent of acute changes of telomere length. Similar observations were made in mononuclear cells (MNC) from these mice and in cultivated bovine aortic endothelial cells, human MNC and endothelial progenitor cells (EPC). Telomerase activation by pioglitazone in cultivated cells was prevented by Akt inhibitors. To test the functional relevance of the findings, isolated mononuclear cells (MNC) were exposed to H(2)O(2). MNC from pioglitazone-treated mice exhibited reduced apoptosis (AnnexinV-FACS). In vivo, lipopolysaccharide-induced aortic endothelial apoptosis was potently prevented in pioglitazone-treated animals (hairpin oligonucleotide assay). Both, up-regulation of telomere-regulating proteins and prevention of oxidative stress-induced aortic apoptosis, were absent in telomerase reverse transcriptase (TERT)-deficient mice ... The findings underscore the important role of telomere-regulating proteins for vascular cell function and survival" - Note:  My doctor says I'm crazy but I've been taking pioglitazone for anti-aging for years.

FDC and pioglitazone increased high-density lipoprotein cholesterol by 14.20% and 9.88%, respectively, vs an increase of 6.09% with metformin (P<.05, metformin vs FDC). Triglycerides decreased with all three treatments -5.95%, -5.54% and -1.78%, respectively; P=not significant). FDC and pioglitazone significantly decreased small low-density lipoprotein and increased large low-density lipoprotein particle concentrations. Reductions in high-sensitivity C-reactive protein were greater in the FDC and pioglitazone groups. Increases in adiponectin were significant in the FDC and pioglitazone groups (P<.0001 vs metformin). Overall, adverse events were not higher with the FDC. Thus, treatment with the FDC resulted in improved levels of CV biomarkers, which were better than or equal to monotherapy"

TZD significantly increased expression (3-fold) and secretion of total (1.4-fold) but not HMW adiponectin. Combined supplementation resulted in a significant increase in expression (3-fold) and secretion of total (1.8-fold) and HMW (5-fold) adiponectin. Similar results were seen in cells co-treated with TNFα" - See my adiponectin page.  High adiponectin is a good thing.  Actos (pioglitazone) is a TZD and is something I've been taking for anti-aging for some time.  Not only does it increase adiponectin but it increases insulin sensitivity.  See my Insulin and Aging page.  See pioglitazone at OffshoreRX.com.
• Fat redistribution preferentially reflects the anti-inflammatory benefits of pioglitazone treatment - Metabolism. 2010 Jan 19 - "high-sensitivity C-reactive protein (hsCRP) ... Pioglitazone treatment for 12 weeks decreased serum hsCRP levels (0.83 [1.14] to 0.52 [0.82] mg/L, P < .001) and improved glycemic control (fasting glucose, P < .001; glycosylated hemoglobin, P < .001) and lipid profiles (triglyceride, P = .016; high-density lipoprotein cholesterol, P < .001). Between responders and nonresponders to the hsCRP-lowering effect of pioglitazone, there were significant differences in baseline hsCRP levels and changes in the postprandial glucose and the ratio of visceral fat thickness (VFT) to subcutaneous fat thickness (SFT) (P = .004, .011, and .001, respectively). The percentage change in hsCRP levels after treatment was inversely correlated with baseline hsCRP levels (r = -0.497, P < .001) and directly correlated with the change in postprandial glucose (r = 0.251, P = .021), VFT (r = 0.246, P = .030), and VFT/SFT ratio (r = 0.276, P = .015). Logistic regression analysis revealed that the hsCRP-lowering effect of pioglitazone was affected by baseline hsCRP levels (odds ratio [OR] = 7.929, P = .007) as well as changes in postprandial 2-hour glucose (OR = 0.716, P = .025) and VFT/SFT ratio (OR = 0.055, P = .009). In conclusion, treatment with pioglitazone produced an anti-inflammatory effect, decreasing serum hsCRP levels; and a decrease in the VFT/SFT ratio was independently and most strongly associated with the hsCRP-decreasing effect. These results suggest that abdominal fat redistribution preferentially reflects the anti-inflammatory benefits of pioglitazone treatment"
• Pioglitazone Reduces ER Stress in the Liver: Direct Monitoring of in vivo ER Stress Using ER Stress-activated Indicator Transgenic Mice - Endocr J. 2009 Sep 29 - "8 weeks of pioglitazone treatment reduced the accumulation of fat droplets in the liver and attenuated the development of insulin resistance. In the liver of the ERAI transgenic mice, ERAI fluorescence activity was clearly reduced as early as after 4 weeks of pioglitazone treatment, preceding the improvement of insulin resistance. In addition, after the pioglitazone treatment, serum free fatty acid and triglyceride levels were decreased, and serum adiponectin levels were increased. These data indicate that pioglitazone treatment suppresses ER stress in the liver which may explain, at least in part, the pharmacological effects of pioglitazone to reduce insulin resistance"

• Pioglitazone Improves Cardiac Function and Alters Myocardial Substrate Metabolism Without Affecting Cardiac Triglyceride Accumulation and High-Energy Phosphate Metabolism in Patients With Well-Controlled Type 2 Diabetes Mellitus - Circulation. 2009 Apr 6 - "were assigned to pioglitazone (30 mg/d) or metformin (2000 mg/d) and matching placebo for 24 weeks ... No patient developed heart failure. Both therapies similarly improved glycemic control, whole-body insulin sensitivity, and blood pressure. Pioglitazone versus metformin improved the early peak flow rate (P=0.047) and left ventricular compliance. Pioglitazone versus metformin increased myocardial glucose uptake (P<0.001), but pioglitazone-related diastolic improvement was not associated with changes in myocardial substrate metabolism. Metformin did not affect myocardial function but decreased cardiac work relative to pioglitazone (P=0.006), a change that was paralleled by a reduced myocardial glucose uptake and fatty acid oxidation. Neither treatment affected cardiac high-energy phosphate metabolism or triglyceride content. Only pioglitazone reduced hepatic triglyceride content" - I still take pioglitazone even though I don't have diabetes because I feel that higher glucose levels are a major cause of aging.  There doesn't seem to be any evidence that it has the heart rises that rosiglitazone has.  See Pioglitazone at OffshoreRX.com.

• The PPARgamma agonist pioglitazone is effective in the MPTP mouse model of Parkinson's disease through inhibition of monoamine oxidase B - Br J Pharmacol. 2008 Mar 10 - "The peroxisome proliferator-activated receptor-gamma (PPARgamma) agonist pioglitazone has previously been shown to attenuate dopaminergic cell loss in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of Parkinson's disease, an effect attributed to its anti-inflammatory properties. In the present investigation, we provide evidence that pioglitazone is effective in the MPTP mouse model, not via an anti-inflammatory action, but through inhibition of MAO-B, the enzyme required to biotransform MPTP to its active neurotoxic metabolite 1-methyl-4-phenylpyridinium (MPP+) ... Mice treated with MPTP showed deficits in motor performance, marked depletions in striatal dopamine levels and a concomitant reduction in TH immunoreactivity in the substantia nigra.

• Metformin and pioglitazone: Effectively treating insulin resistance - Curr Med Res Opin. 2006;22 Suppl 2:S27-37 - "The different insulin-sensitizing mechanisms of metformin and the thiazolidinediones are manifest in partially distinct effects on hepatic and peripheral glucose homeostasis, and clinical studies show improved glucose control with combination therapy. Both metformin and thiazolidinediones may also have pancreatic beta-cell preserving properties. Furthermore, they have different beneficial effects on several other metabolic risk markers and risk factors for cardiovascular disease. Whereas the thiazolidinediones (particularly pioglitazone) have greater effects on multiple aspects of dyslipidemia, metformin has anorexigenic properties. They also have distinct effects on levels of mediators involved in inflammation and endothelial dysfunction, and outcome studies suggest that either pioglitazone or metformin may reduce the risk of macrovascular events"
• A fixed-dose combination of pioglitazone and metformin: A promising alternative in metabolic control - Curr Med Res Opin. 2006;22 Suppl 2:S39-48 - "Pioglitazone increases insulin sensitivity, while metformin reduces hepatic gluconeogenesis and improves peripheral glucose uptake. Both agents reduce hyperglycemia and hyperinsulinemia, and appear to protect beta-cell function ... In randomized studies, pioglitazone and metformin administered separately provided significantly better glycemic control than metformin monotherapy or metformin plus gliclazide. Pioglitazone and metformin have complimentary benefits on diabetic dyslipidemia; pioglitazone primarily improves high-density lipoprotein cholesterol and triglyceride levels (to a greater extent than rosiglitazone does), while metformin mainly improves total cholesterol. Pioglitazone and metformin also modulate other atherosclerosis biomarkers, including inflammatory mediators, coagulation thrombosis components, and carotid intima media thickness. Together, these pleiotropic effects have the potential to confer a reduced risk of cardiovascular disease in patients with type 2 diabetes. Pioglitazone and metformin are well tolerated in combination, with low rates of hypoglycemia, and the convenience of a single tablet may be expected to aid dosing compliance"
