Fig. 5. Exposure to PM2.5 induces expression of endoplasmic reticulum stress marker molecules in livers of rats in different groups. A and B: ATF6, GRP78 and CHOP expression of mRNA and protein; C: ATF6, GRP78 and CHOP protein bands. Mean expressions of mRNA and protein in each treated group are shown as increases compared to the mean expression in the control group, which has been ascribed an arbitrary value of 1. The values are mean ± SD from five individual samples. Using one-way ANOVA, compared with the control group, significant difference is indicated by *P < 0.05 and **P < 0.01.
