MTT assay wasused to evaluated H9C2 cells viability. H9C2 cells were divided into normal control group, triptolide group, lipopolysaccharide(LPS) group, drug-containing serum group and mi RNA-21 inhibitor group. micro RNA-21(mi RNA-21) inhibitor was structured and transfected into H9C2 cells. Western blot and immunofluorescence assay were applied to examine toll-like receptor 4(TLR4), phosphorylated p-38(p-p38) and p-p65 expression. Quantitative real-time PCR(q RT-PCR) was used to evaluated m RNA levels of mi RNA-21. Enzyme linked immunosorbent(ELISA) was used to measure tumor necrosis factor α(TNF-α), IL-6 and IL-17 levels.RESULTS: Drug-containing serum treatment significantly increased cell viability compared to LPS treated group. q RT-PCR results indicated that mi RNA-21 levels were significantly decreased in drugcontaining serum group compared to LPS group.Early and late apoptosis in drug-containing serum group were significantly decreased compared to LPS group. Western blot and immunofluorescence assay results showed that TLR4, p-p38 and p-p65 levels in drug-containing serum group were significantly decreased compared to LPS group. ELISA findings indicated that drug-containing serum significantly decreased inflammatory cytokine levels of TNF-α, IL-6 and IL-17.CONCLUSION: Drug-containing serum of Xinfeng capsules protect against lipopolysaccharide instructed H9C2 cells from death by enhancing mi RNA-21 and inhibiting TLR4/p-p38/p-p65 signaling pathway and proinflammatory cytokines expression.展开更多
