We previously found that cathepsin K (CTSK) played an important role in adipocyte differentiation. However, the underlying molecular mechanism is not clear. Through the time window study, it was observed that CTSK activities were required mainly in the early phases of adipogenic process. At the same time, the expression of type I collagen disappeared.(More)
SIRT1 has been demonstrated in nutrient-sensing and insulin-signaling pathways in in vivo and in vitro experiments, but there is minimal information concerning the association between gene polymorphisms of SIRT1 and type 2 diabetes mellitus (T2DM) in a Chinese Han population. Using case-control design, we recruited 310 unrelated T2DM patients from(More)
BACKGROUND Roux-en-Y gastric bypass (RYGB) surgery is currently the most effective treatment for substantial and sustained weight loss in morbidly obese individuals. We aim to determine the prevalence in Chinese obese patients with type 2 diabetes (T2DM) and the efficacy of surgical treatment of the metabolic syndrome (MetS) and its components with a(More)
Glucagon-like peptide-1 (GLP-1) is an incretin hormone that regulates glucose homeostasis. Because of their direct stimulation of insulin secretion from pancreatic β cells, GLP-1 receptor (GLP-1R) agonists are now important therapeutic options for the treatment of type 2 diabetes. To better understand the mechanisms that control the insulinotropic actions(More)
BACKGROUND Recent studies highlight a negative association between total bilirubin concentrations and albuminuria in patients with type 2 diabetes mellitus. Our study evaluated the relationship between bilirubin concentrations and the prevalence of diabetic nephropathy (DN) in Chinese patients with type 1 diabetes mellitus (T1DM). METHODS A total of 258(More)
BACKGROUND Some nondiabetic trauma patients with hyperglycemia have been found to have occult diabetes mellitus (ODM). We studied whether glycated albumin (GA) was an effective tool for detecting ODM in orthopedic trauma patients with elevated glucose levels. METHODS A cross-sectional, sequential case series study of adult patients presenting to the(More)
A 57-year-old woman with type 2 diabetes was admitted to our hospital presenting with generalized bone pains, hypercalcemia, and elevated parathyroid hormone level. Enhanced CT scan demonstrated a large soft tissue mass in the right anterior mediastinum. Tc-MIBI scintigraphy revealed the focal accumulation of radiotracer uptake in the anterior mediastinum.(More)
BACKGROUND This study was conducted to evaluate the prevalence of iron-deficiency anemia (IDA) after Roux-en-Y gastric bypass (RYGB) in Chinese obese patients with type 2 diabetes (T2DM). Furthermore, we evaluate potential predicting factors for onset of IDA after RYGB. METHODS A total of 184 obese T2DM individuals who underwent RYGB were enrolled in the(More)
Glucagon regulates glucose homeostasis by controlling glycogenolysis and gluconeogenesis in the liver. Exaggerated and dysregulated glucagon secretion can exacerbate hyperglycemia contributing to type 2 diabetes (T2D). Thus, it is important to understand how glucagon receptor (GCGR) activity and signaling is controlled in hepatocytes. To better understand(More)
