a HCT116 and SW480 cells were treated with tunicamycin for the indicated time. Cell lysates were analyzed for the expression of PHLPP1, PHLPP2, ATF4 and eIF2α and β-actin using Western blot. The phosphorylation status of eIF2α was detected using the phospho-eIF2α (p-eIF2α) antibody. The relative expression levels of PHLPP1 and PHLPP2 were obtained by normalizing to β-actin. b The relative expression of LC3B (gene name MAP1LC3B), BECN1 (beclin1), ATG12, PHLPP1, and PHLPP2 mRNA was determined using RT-qPCR following the treatment with tunicamycin for 24 h in HCT116 and SW480 cells. Data represent the mean ± SD (¶p < 0.0001, & p < 0.001 and *p < 0.05).
