Abstract

To study the influence of micro ribonucleic acid (miR)-21 on the renal interstitial fibrosis (RIF) model mice, and to preliminarily elucidate the mechanism of action of miR-21 in the development of RIF by studying the influences of miR-21 on the expressions of the proteins related to the extracellular signal-regulated kinase (ERK) 1/2 signaling pathway and its downstream proteins. The mouse model of the left unilateral ureteral obstruction (UUO) was established. The experimental mice were divided into the Sham group and UUO group and were normally fed for 3 weeks. Then, they were executed, and their blood was extracted to determine the renal function-related indicators. The left kidney was excised, and the corresponding specimens were reserved for observing the appearance of the kidney and the morphology of the renal tubules and interstitium. The relative expression levels of epithelial (E-)cadherin, α-smooth muscle actin (α-SMA), and ERK1/2 phosphorylated ERK1/2 (p-ERK1/2), the transforming growth factor-β1 (TGF-β1) and the connective tissue growth factor (CTGF) proteins in renal tissues were determined. After the human renal proximal tubular epithelial cell line, the human kidney-2 (HK-2) was treated with high glucose (HG) co...Continue Reading

Cadherins and Catenins

Cadherins (named for "calcium-dependent adhesion") are a type of cell adhesion molecule (CAM) that is important in the formation of adherens junctions to bind cells with each other. Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells: alpha-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins.
