Therapy targeting mitochondria may provide novel ways to treat diabetes and its complications. Bone marrow-derived mesenchymal stem cells (MSCs), the peroxisome proliferator-activated receptor gamma (PPAR-γ) agonists and exendin-4; an analog of glucagon-like peptide-1 have shown cardioprotective properties in many cardiac injury models. So, we evaluated their effects in diabetic cardiomyopathy (DCM) in relation to mitochondrial dysfunction. This work included seven groups of adult male albino rats: the control group, the non-treated diabetic group, and the treated diabetic groups: one group was treated with MSCs only, the second with pioglitazone only, the third with MSCs and pioglitazone, the forth with exendin-4 only and the fifth with MSCs and exendin-4...

Fournier's gangrene (FG) is a fulminant infective necrotizing fasciitis, which includes the genital, perineal, and perianal regions. A 77-year-old man had previously been diagnosed as having diabetes mellitus (DM) and was treated with pioglitazone (15 mg) and miglitol (150 mg). He developed sudden perineal discomfort, fever with painful penile, and scrotal edema, subsequently leading to urinary retention. According to physical examination and CT scan results for the swollen penis and scrotum, he was diagnosed with FG...

Importance: Nonalcoholic steatohepatitis (NASH) is projected to be the leading cause of liver transplantation by 2020. Advanced fibrosis (stage F3-F4) on liver biopsy independently predicts all-cause and liver-related mortality in NASH. There are no known efficacious treatments for advanced fibrosis related to NASH. Thiazolidinedione therapy has been extensively evaluated in NASH, and new randomized clinical trials (RCTs) of its efficacy have been completed. Objective: To synthesize the evidence about the association of thiazolidinedione therapy with advanced liver fibrosis in NASH...

The study aims to investigate the effect of vitamin D (VD) combined with pioglitazone hydrochloride (PIO) on bone mineral density (BMD) and bone metabolism in patients with type 2 diabetic nephropathy (T2DN). T2DN patients were selected and assigned into mild, moderate and severe groups. In each group, three therapy regimens (VD, PIO, and VD plus PIO) were administrated. X-ray absorptiometry was used to measure BMD. Intact parathyroid hormone (iPTH) and 25-OH-VD3 were measured by chemiluminescence meter. ELISA was applied to detect levels of osteoprotegerin (OPG), bone gla protein (BGP), C-terminal telopeptides of type I collagen (β-CTX), procollagen type I N propeptide (PINP), pyridinoline (Pyr), and deoxypyridinoline (D-Pyr)...

Liver-related diseases are the leading causes of death in patients with type 2 diabetes mellitus (T2DM) in Japan. Type 2 diabetes mellitus is closely associated with non-alcoholic fatty liver disease (NAFLD), which is the most prevalent chronic liver disease worldwide. Non-alcoholic steatohepatitis (NASH), a severe form of NAFLD, can lead to hepatocellular carcinoma and hepatic failure. Non-alcoholic steatohepatitis can be called "diabetic hepatopathy". There are no established pharmacotherapies for NAFLD/NASH patients with T2DM...

Long-term use of thiazolidinediones (TZDs) is associated with bone loss and an increased risk of fracture in patients with type 2 diabetes (T2DM). Incretin-based drugs (glucagon-like peptide-1 (GLP-1) agonists and dipeptidylpeptidase-4 (DPP-4) inhibitors) have several benefits in many systems in addition to glycemic control. In a previous study, we reported that exendin-4 might increase bone mineral density (BMD) by decreasing the expression of SOST/sclerostin in osteocytes in a T2DM animal model. In this study, we investigated the effects of a DPP-4 inhibitor on TZD-induced bone loss in a T2DM animal model...

Osteoarthritis (OA) is the most frequent joint disorder and one of the leading cause of disability. During a long time, it was considered as the consequence of aging and mechanical stress on cartilage. Recent advances in the knowledge of OA have highlighted that it is a whole joint disease with early modifications of synovium and subchondral bone but also that it is associated with obesity and metabolic syndrome through systemic mechanisms. In the past year, type 2 diabetes has been described in two meta-analyzes as an independent risk factor for OA...

AIMS/HYPOTHESIS: The treatment of type 2 diabetes with full peroxisome proliferator-activated receptor gamma (PPARγ) agonists improves insulin sensitivity, but is associated with weight gain, heart failure, peripheral oedema and bone loss. Endotrophin, the C-terminal fragment of the α3 chain of procollagen type VI (also called Pro-C6), is involved in both adipose tissue matrix remodelling and metabolic control. We established a serum assay for endotrophin to assess if this novel adipokine could identify type 2 diabetic patients who respond optimally to PPARγ agonists, improving the risk-to-benefit ratio...

To determine the efficacy of pioglitazone to prevent type 2 diabetes in older compared to younger adults with pre-diabetes. Six hundred two participants with impaired glucose tolerance (IGT) were randomized in double blind fashion to placebo or pioglitazone for diabetes prevention in the ACT NOW study (NEJM 364:1104-1115, 2011). Cox proportional hazard regression was used to compare time to development of diabetes over a mean of 2 years between older (≥61 years) and younger participants. We compared effects of pioglitazone versus placebo on metabolic profiles, inflammatory markers, adipokines, β cell function (disposition index), insulin sensitivity (Matsuda index), and body composition by ANOVA...

Thiazolidinediones are traditional anti‑diabetic therapeutic agents that have been associated with bone loss and increased fracture risk. However, the underlying mechanisms of this side effect require further elucidation. The present study aimed to investigate the effect of pioglitazone (PIO), a thiazolidinedione, on osteoblastogenesis, osteoclastogenesis and the osteoprotegerin (OPG) / receptor activator of nuclear factor‑κB ligand (RANKL) / RANK system. The MC3T3‑E1 murine pre‑osteoblastic cell line was treated with PIO and processed for reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) analysis of OPG, RANKL, peroxisome proliferator‑activated receptor γ (PPARγ), Runt‑related transcription factor 2 (RUNX2), alkaline phosphatase (ALP) and osteocalcin (OCN), and western blotting analysis of OPG and RANKL...

The prevention of recurrent events after ischaemic stroke and transient ischaemic attack is well established and based on lifestyle changes, antithrombotics, statins, antihypertensives and carotid surgery. The international IRIS trial assessed whether pioglitazone, a glucose-lowering insulin-sensitizing drug, would reduce recurrent vascular events in patients with ischaemic stroke or transient ischaemic attack. After 4.8 years, pioglitazone therapy was associated with reduced vascular events and new diabetes, and an increase in weight, oedema and bone fractures...

Classically activated macrophages (M1) are associated with inflammation in diabetic patients. Inflammation is a known risk factor in diabetes. The present study tested the hypothesis that pioglitazone (PIO) alleviates inflammation in diabetic mice fed a high-fat diet by inhibiting advanced glycation end-product (AGE)-induced classical macrophage activation. It was found that AGE treatment promoted the transcription of pro-inflammatory molecules and M1 surface markers, whereas PIO increased the expression of anti-inflammatory genes and decreased the expression of pro-inflammatory mediators in bone marrow-derived macrophages (BMDMs) in a dose-dependent manner...

The present study aimed to investigate the effects of bone marrow‑derived mesenchymal stem cells (BMSCs) that had been pretreated with pioglitazone and/or rosiglitazone on the growth and proliferation rate of MCF‑7 cells. The adhesive interaction between the BMSCs and the MCF‑7 cancer cells revealed that the pretreatment of BMSCs with a combination of two types of thiazolidinedione drug reduced the growth and proliferation rate of the MCF‑7 cells. The proliferation rate of the MCF‑7 cells could also be reduced by the non‑adhesive interaction of the cancer cells with BMSCs pretreated with pioglitazone and/or rosiglitazone...

Long non-coding RNA (lncRNA) maternally expressed 3 (MEG3) is expressed in endothelial cells and involved in angiogenesis and vascular function. It was proposed that MEG3 participates in the process of endothelial progenitor cells (EPCs) functions in metabolic syndrome (MetS). In this study, the circulating EPCs number and function were decreased in MetS subjects. The MEG3 expression was expressed at a lower level and microRNA-140-5p (miR-140-5p) was expressed at a higher level in circulating EPCs of subjects with MetS...

BACKGROUND: Patients with ischemic stroke or transient ischemic attack (TIA) are at increased risk for future cardiovascular events despite current preventive therapies. The identification of insulin resistance as a risk factor for stroke and myocardial infarction raised the possibility that pioglitazone, which improves insulin sensitivity, might benefit patients with cerebrovascular disease. METHODS: In this multicenter, double-blind trial, we randomly assigned 3876 patients who had had a recent ischemic stroke or TIA to receive either pioglitazone (target dose, 45 mg daily) or placebo...

Metabolic dysfunction that occurs in obesity and Type 2 diabetes results in a low-level inflammatory state which impacts on mesenchymal stem cells (MSCs) capacity to promote wound healing. The ability of either recombinant Interleukin-6 (rIL6) or pioglitazone to modulate MSC migration, essential for wound healing, by targeting the inflammation-modulated IL6/STAT3 signalling pathway was therefore investigated in bone marrow-derived MSCs from control (C57BL/6J) and pre-diabetic obese mice (B6. Cg-Lepob/J). The population doubling time, in vitro wound closure and mRNA expression profile of 84 genes involved in the IL6/STAT3 signalling pathway were assessed...

Pioglitazone is an insulin-sensitizing thiazolidinedione (TZD) whose use is associated with bone loss. We examined the effects of pioglitazone on components of the Wnt signaling pathway (Wnt1, β-catenin) and markers of bone mineralization [osteoprotegerin (OPG), bone sialoprotein (BSP), fibroblast growth factor (FGF)23] as well as mineral content in human osteoblast hFOB 1.19 cells. hFOB 1.19 cells were cultured in K12/DMD medium with or without pioglitazone. PPARγ Wnt1, OPG, BSP, or FGF23 mRNA expression was measured using qRT-PCR; β-catenin, OPG, BSP, or FGF23 using ELISA; and calcium or phosphate content using colorimetry...
