ABSTRACT
Hepatocyte growth factor (HGF) is a multi-effective molecule, playing important roles in organ growth, tumorigenesis and trauma healing. This experiment aims at studying the promoting function of HGF on the proliferation of human eccrine sweat gland epithelial cells (hESGc) and its relative signal channels. After HGF at different concentrations were added into cells, MTT was adopted to detect the cell proliferations, Annexin-V/PI the cell apoptosis, and Westernblot the expressions of p-AKT, AKT, p-ERK, p-GSK3β, p-IKBα, and β-catenin in hESGc. After adding siRNA c-Met to block HGF or LY294002 to inhibit p-AKT, we used MTT to detect the proliferation of hESGc and Westernblot to detect the expression of β-catenin. As a result, 20-40 ng/mL HGF could promote the proliferation of hESGc and inhibit its apoptosis. HGF could promote the expressions of p-AKT1/2/3, p-ERK, p-GSK3β, p-IKBα, and β-catenin. The additions of siRNA c-Met to block HGF or LY294002 to inhibit p-AKT could downregulate β-catenin and inhibit the proliferation promotion caused by HGF. Consequently, we concluded HGF can promote the proliferation of human eccrine sweat gland epithelial cells, which is relative to AKT signal channel and β-catenin.
