ATF5 is upregulated under ER stress and protects cells from ER stress-induced apoptosis. (A) Relative ATF5 mRNA expression in Myla and H9 cells treated for 24h. Relative expression was normalized to GAPDH and vehicle. Relative ATF5 expressions of vehicle groups were normalized as 1 and indicated by the black dashed line. The red dashed box highlights ER stress inducers treatment. (B, C) Specific apoptosis of control (shNC) and ATF5-KD (sh1, sh2) H9 (B) and Myla (C) cells treated with thapsigargin for 48 h. (D, E) Specific apoptosis of control (shNC) and ATF5-KD (sh1, sh2) H9 (D) and Myla (E) cells treated with tunicamycin for 48 h. Data are presented as mean ± SD and representative of at least three independent experiments. ns, no significance, *P<0.05, **P<0.01, ***P<0.001.
