Figure 5. Emodin mediates the MAPK signaling pathway in HepG2 cells. (A) IF staining of P38, phosphorylated P38, ERK1/2 and phosphorylated ERK1/2 (200×) in HepG2 cells. (B–E) Florescence intensity analysis of P38, phosphorylated P38, ERK1/2 and phosphorylated ERK1/2. (F) Representative Western blot of P38, phosphorylated P38, ERK1/2 and phosphorylated ERK1/2. (G–J) Western blot analysis. *indicates a comparison with NC, P < 0.05. The white line indicates 50 μm.
