In diabetic patients complicated with colorectal cancer (CRC), metformin treatment was reported to have diverse correlation with CRC-specific mortality. In laboratory studies, metformin was reported to affect the survival of cancer stem cells (CSCs) in breast and pancreatic cancers and glioblastoma. Although cscs play a critical role in the resistance to(More)
The goal of this study was to investigate the possible protective effects of sitagliptin against dyslipidemia-related kidney injury in apolipoprotein E knockout (apoE-/-) mice. Eight-week-old male apoE-/- mice were randomized to receive either a high fat diet (HFD, apoE-/- group) or HFD mixed with sitagliptin (sita + apoE-/- group) for 16 weeks. A control(More)
BACKGROUND miR-192, miR-194, and miR-215 are enriched in the kidney and play roles in the pathogenesis of diabetic nephropathy (DN). Extracellular vesicles (EVs) can be detected in body fluids and may serve as disease biomarkers. METHODS Eighty type 2 diabetes patients with normoalbuminuria (n = 30), microalbuminuria (n = 30), or macroalbuminuria (n =(More)
Increasing evidence indicates that brown adipose tissue (BAT) transplantation enhances whole-body energy metabolism in a mouse model of diet-induced obesity. However, it remains unclear whether BAT also has such beneficial effects on genetically obese mice. To address this issue, we transplanted BAT from C57/BL6 mice into the dorsal subcutaneous region of(More)
BACKGROUND The dipeptidyl peptidase-4 inhibitor sitagliptin, a new anti-diabetic medicine, is effective in treating type 2 diabetes mellitus by increasing the activation and duration of action of glucagon-like peptide-1. Since atherosclerosis is the main pathological feature of diabetic cardiovascular complications, it is important to investigate the(More)
Background. White adipose tissue browning may be a promising strategy to combat obesity. UCP1 is strongly induced in White adipose tissue with β3-adrenergic agonist treatment, but the causes of this increase have not been fully elucidated. This study aims to explore more miRNAs involved in the process of browning of visceral adipose tissue. Methods. Total(More)
OBJECTIVE To investigate the effect of metformin in protecting against advanced glycation end products (AGEs)-induced apoptosis in human primary dermal fibroblasts. METHODS Fibroblasts were exposed to 100, 200, or 300 µg/mL AGEs, 300 µg/mL bovine serum albumin (BSA), or 300 µg/mL AGEs and 1 mmol/L metformin for 24, 48, or 72 h. The exposed cells were(More)
MicroRNAs (miRNAs) play vital roles in the development of diabetic nephropathy. Here, we compared the protective efficacies of miR-26a and miR-30c in renal tubular epithelial cells (NRK-52E) and determined whether they demonstrated additive effects in the attenuation of renal fibrosis. TGFβ1 suppressed miR-26a and miR-30c expression but up-regulated(More)
OBJECTIVE The objective of this article is to investigate the renoprotecive effects of exendin-4 in a mouse model of unilateral ureteral obstruction (UUO) and explore the putative mechanisms. METHODS Male Balbc mice underwent sham operation or UUO surgery, and then received intraperitoneal injection of vehicle or exendin-4, respectively. After 14 days,(More)
