miR-200c-3p was associated with ER stress. a The level of miR-200c-3p was increased following thapsigargin (TG) treatment in PC-3 cells. After treatment with TG for 0, 1, 3, 6, 12, and 24 h, cells were lysed and complementary DNA was generated. RT-qPCR analysis was performed to determine the level of miR-200c-3p. U6 small nuclear ribonucleoprotein was used to normalize the expression of miR-200c-3p. b The expression levels of ATF6 and eukaryotic initiation factor (eIF)-2α were increased following TG treatment. RT-qPCR analysis was performed to evaluate the levels of ATF6 and elF2α. Levels of GAPDH were used for normalization. c Viability of PC-3 cells treated with TG in control or miR-200c mimics. Two days after transfection with miR-200c-3p mimic, 0.5 mM TG was added and cells were incubated for 48 h. The MTT assay was used to measure cell viability. Data are presented as the mean ± SEM of triplicate samples. ***p < 0.001, **p < 0.01, and *p < 0.05
