Figure 4. Endoplasmic reticulum stress inhibition by 4-PBA alleviates kaempferol-induced autophagy in HepG2 cells.

Data are expressed as mean ± SD of at least three independent experiments. (A) The mRNA expression levels of Atg5, Atg7 and Beclin1 were determined by qRT-PCR. (B) The protein expression levels of Atg5, Atg7, Beclin1, LC3B, p62and β-actin were determined by western blot and quantified by densitometry.
