HSPA1A knockdown decreases fat accumulation in NAFLD. HepG2 cells were transfected with vector or HSPA1A siRNA, and the lipids were stained with Oil Red O and analysed by microscopy (a, d). Hsp70 protein (b) expression levels were evaluated by Western blot and normalized to β-actin levels. Data are expressed as the mean ± SD (n = 6, each). **P < 0.01 compared with the control group (b, c)
