Sirtuin1 (SIRT1) Regulates Tumor Necrosis Factor-alpha (TNF-α-Induced) Aquaporin-2 (AQP2) Expression in Renal Medullary Collecting Duct Cells Through Inhibiting the NF-κB Pathway
BACKGROUND Aquaporin-2 (AQP2) plays a major role in water reabsorption in the renal collecting duct, and is involved in a variety of renal disease. Recent studies have indicate that sirtuin1 (SIRT1) exerts renoprotective properties against kidney diseases. This study aimed to determine the potential role of SIRT1 in AQP2 expression induced by tumor necrosis factor-alpha (TNF-α) and to disclose ...
متن کاملMiRNA-181a Regulates Adipogenesis by Targeting Tumor Necrosis Factor-α (TNF-α) in the Porcine Model
Adipogenesis is tightly regulated by altering gene expression, and TNF-α is a multifunctional cytokine that plays an important role in regulating lipogenesis. MicroRNAs are strong post-transcriptional regulators of cell differentiation. In our previous work, we found high expression of miR-181a in a fat-rich pig breed. Using bioinformatic analysis, miR-181a was identified as a potential regulat...
متن کاملTUMOR NECROSIS FACTOR ALPHA (TNF-a)
Tumor necrosis factor alpha (TNF, TNFSF2) is an important multifunctional cytokine that regulates inflammation, host defense, immune responses, and apoptosis. TNF exists as a membrane-bound 26kDa, type II integral membrane protein, and a 17kDa soluble homotrimeric TNF that is generated via proteolytic cleavage by TNF-a converting enzyme (TACE, ADAM17). Both the membrane-bound and soluble forms ...
متن کاملVascular endothelial growth factor synergistically enhances induction of E-selectin by tumor necrosis factor-alpha.
OBJECTIVE The regulation of endothelial cell adhesion molecules (CAMs) by vascular endothelial growth factor (VEGF) was investigated in cell cultures and in a rabbit model of atherogenic neointima formation. METHODS AND RESULTS VEGF regulation of vascular CAM-1 (vascular cell adhesion molecule), intercellular CAM-1 (intercellular adhesion molecule), and E-selectin were investigated in human u...
متن کاملRole of A20 in cIAP-2 Protection against Tumor Necrosis Factor α (TNF-α)-Mediated Apoptosis in Endothelial Cells
Tumor necrosis factor α (TNF-α) influences endothelial cell viability by altering the regulatory molecules involved in induction or suppression of apoptosis. However, the underlying mechanisms are still not completely understood. In this study, we demonstrated that A20 (also known as TNFAIP3, tumor necrosis factor α-induced protein 3, and an anti-apoptotic protein) regulates the inhibitor of ap...
