1. MicroRNAs (miRNAs) play essential roles in many biological processes. It is known that aberrant miRNA expression contributes to some pathological conditions. However, it is not known whether miRNAs play any role in the development of insulin resistance in adipocytes, a key pathophysiological link between obesity and diabetes. 2. To investigate the(More)
1. Adipocyte hypertrophy and hyperplasia are important processes in the development of obesity. To understand obesity and its associated diseases, it is important to elucidate the molecular mechanisms governing adipogenesis. MicroRNA-375 has been shown to inhibit differentiation of neurites, and participate in the regulation of insulin secretion and blood(More)
Heme oxygenase (HO) is a rate-limiting enzyme of heme degradation, which converts the cellular heme to bilirubin and carbon monoxide (CO). Recently it is suggested that endogenous CO plays an important role in regulating vascular tone under both physiological and pathological conditions, but it is not clear whether endogenous HO/CO system regulates vascular(More)
To investigate the effects of the sensitizer rosiglitazone on the proliferation of vascular smooth muscle cell (VSMC) induced by high glucose administration. VSMCs were isolated from rat thoracic aortas and cultured in 10% fetal bovine serum (FBS). VSMC proliferation was evaluated by methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay and cell counting.(More)
OBJECTIVE To study the role of nitric oxide synthase/nitric oxide pathway in the pathophysiological process of intussusception (IN). METHODS The IN model of rat was induced by lipopolysaccharide (LPS). The content of NOx in plasma and the NOS activity in colic smooth muscle tissues were measured. The content of cGMP was determined by radioimmunoassay. (More)
We examined the effect of microRNAs on 3T3-L1 adipocyte differentiation and expression of adipocyte-specific gene fatty acid-binding protein 4 (FABP4). We screened and identified adipo-related microRNAs during 3T3-L1 adipocyte differentiation with a microRNA microarray. High expression plasmids of miR-24 and miR-21 were constructed and transfected into(More)
microRNA-24 (miR-24) belongs to miR-23~27~24 cluster. It is highly expressed in vascular endothelial cells (VECs), and plays an important role in the regulation of VECs specific gene expression. Recent studies indicate that miR-24 is involved in the regulation of VECs function such as proliferation, apoptosis, angiopoiesis, inflammation, and(More)
MicroRNAs are endogenous small RNAs with a high degree of conservation, participating in a variety of vital activities. In present study, to explore the effect of microRNAs on 3T3-L1 adipocyte differentiation and adiponectin expression, the adipo-related microRNAs were screened and identified by micorRNA microarray. The highly expression plasmid of(More)
