Fig. 3From: Down-regulation of USP13 mediates phenotype transformation of fibroblasts in idiopathic pulmonary fibrosisKnockdown of USP13 through RNA interference. MRC-5 cells were transfected with negative control siRNA (NCsi) or two different USP13 siRNAs (USP13si #1 and #2) for 24 h or 48 h. a Graph of USP13 mRNA levels at both 24 h and 48 h in USP13 siRNA-treated cells. b Graph of USP13 protein levels at 24 h or 48 h after USP13 siRNA transfection. c Protein expression levels of representative samples are shown. Error bars indicate the mean ± SEM. *p <0.05, **p <0.01Back to article page
