Fig 1: Western blot analysis of endogenous NFATC4, STIM1, and PPP3R1 protein levels in miR-34a-5p-overexpressing Jurkat cells.a, b Representative western blot images. Jurkat cells were transfected for 48 h either with non-targeting control (ANC) or synthetic miR-34a-5p mimic. NFATC4, STIM1, and PPP3R1 protein was detected by specific monoclonal antibodies in western blot analysis. ß-Actin served as loading control. c–e Quantification of NFATC4, STIM1, and PPP3R1 expression by densitometric analysis of three independent western blot experiments. Respective protein expression was standardized according to ß-Actin loading control and expression level of the control transfected cells was set to 100%. Results are shown as means of five independent experiments with corresponding standard errors (SEM). Statistical evaluation was performed using Student’s t-test. A normal distribution of the data was assumed.
