The prevalence of metabolic syndrome (MS) has been on the rise over the past few decades, and this is associated with an increased incidence of target organ damage such as left ventricular hypertrophy (LVH). This meta-analysis aims to evaluate the features of LVH in MS patients with or without high blood pressure (BP).

Reduction of pancreatic β-cell mass is a key element leading to type 2 diabetes. Obesity and overweight with high levels of lipids including cholesterol are tightly linked to type 2 diabetes. The direct impact of cholesterol on pancreatic β-cells, however, has not been extensively studied. In this study, MIN6 mouse β-cell line was used to test the effect of cholesterol on pancreatic β-cell apoptosis...
Pancreatic β-cell dysfunction is an important pathological change in type 2 diabetes, which is tightly related to obesity. However, the direct role of adipose tissue in β-cell dysfunction has not been well understood. In this study, we examined the effects of 3T3-L1 adipocytes on MIN6 insulin-secreting cells in a co-culture system. MIN6 cells used here kept most of β-cell functions but less sensitive...
Extracellular adenosine triphosphate (ATP) has distinct effects on insulin secretion from pancreatic β-cells between rats and mice. Using a confocal microscope, we compared changes between rats and mice in cytosolic free calcium concentration ([Ca2+]c) in pancreatic β-cells stimulated by extracellular ATP. Extracellular ATP (50 µM) induced calcium release from intracellular calcium stores by activating...
