Downregulation of CPPED1 Expression Improves Glucose Metabolism In Vitro in Adipocytes
نویسندگان
چکیده
We have previously demonstrated that the expression of calcineurin-like phosphoesterase domain containing 1 (CPPED1) decreases in adipose tissue (AT) after weight reduction. However, the function of CPPED1 in AT is unknown. Therefore, we investigated whether the change in CPPED1 expression is connected to changes in adipocyte glucose metabolism. First, we confirmed that the expression of CPPED1 decreased after weight loss in subcutaneous AT. Second, the expression of CPPED1 did not change during adipocyte differentiation. Third, CPPED1 knockdown with small interfering RNA increased expression of genes involved in glucose metabolism (adiponectin, adiponectin receptor 1, and GLUT4) and improved insulin-stimulated glucose uptake. To conclude, CPPED1 is a novel molecule involved in AT biology, and CPPED1 is involved in glucose uptake in adipocytes.

Cinnamon Extract Changes the Expression of miRNAs26-b, 29a, 223 and320 in Insulin Resistant Adipocytes
Objective: Insulin resistance (IR) is the major cause in Type 2 diabetes mellitus (T2DM). Expression of some miRNAs can be changed in response to a drug treatment for IR, and used as the biomarker in IR. This study set out to determine the effect of cinnamon extract (cinnamaldehyde) on some miRNAs expression in IR adipocytes. Materials and Methods: In this In-vitro study the 3T3L1 cells were e...
متن کاملSoy Isoflavone Genistein Is a Potential Agent for Metabolic Syndrome Treatment: A Narrative Review
Metabolic syndrome has a high prevalence (about 22.4% in adult individuals) in developed countries. Inflammation due to obesity and fat accumulation is the most important factor in the progression of metabolic syndrome. In cells which have a receptor for insulin hormone, inflammatory mediators target the insulin signaling pathway and cause insulin resistance. Peroxisome proliferator-activated r...

متن کاملPolychlorinated biphenyls-153 induces metabolic dysfunction through activation of ROS/NF-κB signaling via downregulation of HNF1b
Polychlorinated biphenyls (PCB) is a major type of persistent organic pollutants (POPs) that act as endocrine-disrupting chemicals. In the current study, we examined the mechanism underlying the effect of PCB-153 on glucose and lipid metabolism in vivo and in vitro. We found that PCB-153 induced per se and worsened high fat diet (HFD)-resulted increase of blood glucose level and glucose and ins...

Cyclic AMP promotes chronic expression of target genes mainly by protein kinase A-dependent activation of CREB transcription factor machineries in the metabolic tissues. Here, we wanted to elaborate whether CREB-regulated transcription factor (CRTC)2 and its negative regulator salt-inducible kinase (SIK)2 are involved in the transcriptional control of the metabolic pathway in adipocytes. SIK2 k...
