Tumor necrosis factor-like weak inducer of apoptosis promotes expression of matrix metalloproteinase 2 and collagen Ⅰ in rat cardiac fibroblasts via the ERK1/2 signaling pathway
Objective To explore the mechanism of tumor necrosis factor-like weak inducer of apoptosis( TWEAK)mediating the expression of MMP2 and collagen Ⅰ in cultured neonatal rat cardiac fibroblasts( CFs). Methods CFs were isolated and cultured using trypsin enzyme digestion technique. The protein expression of phosphorylated-ERK( p-ERK1 /2) was detected with Western blotting,and then the optimal interventional concentration and duration of rh TWEAK and inhibitor PD98059 on ERK1 /2 pathway in CFs were determined.
