Fig. 3. piR-57125 regulates CCL3 expression.

Fig. 3

a Volcano map represents the differentially expressed genes upon piR-57125 overexpression in OSRC-2 cells from RNA-seq. The experiments were carried out three times with the p < 0.05, |log2FC| > 0. b, c Decreased or increased mRNA (b) or protein (c) expression of CCL3 in 786-O cells via transfection with piR-57125 inhibitors or mimics respectively. Data represent mean ± S.D. from three independent experiments. d ELISA experiment showed that the secretion of CCL3 proteins from ccRCC cells was respectively increased or decreased upon knockdown or overexpression of piR-57125. Data represent mean ± S.D. from three independent experiments. e RIP and RT-qPCR assays revealed that piR-57125 and CCL3 mRNA had more affinity with PIWIL4 compared with the IgG control. Data represent mean ± S.D. from three independent experiments. f Luciferase reported plasmids which contained WT or Mut 3’UTR region of CCL3 were combined with piR-57125 or control mimics, and transfected into HEK-293T cells. The relative luciferase activity was normalized with renilla luciferase. Data represent mean ± S.D. from three independent experiments. *p < 0.05; **p < 0.01; ***p < 0.001.
