Overexpresssion of miR-32 suppresses tumor necrosis factor receptor-associated factor 3(TRAF3) protein expression. (a) Western blot analysis for TRAF3 in CHME3 cells after miR-32 overexpression. Plasmid pCMV-miR-32 was transfected into CHME3 cells. The empty vector was used as the negative control. Cell lysates were prepared after 24 hours of transfection, and western blot analysis was performed using anti-TRAF3 antibody. miR-32 overexpression significantly reduced both mRNA and protein levels of TRAF3 (P ≤ 0.05) (indicated by * in the transfected group) compared with empty vector. (b) Quantitative (q)PCR analysis of miR-32 overexpression in CHME3 cells, using TaqMan miR-32 assay. miR-32 expression was found to be 7.5-fold higher in miR-32-overexpressed cells. (c) Densitometry quantification of TRAF3 normalized to β-tubulin. (d) qPCR analysis for detection of changes in transcript level of TRAF3 after miR-32 overexpression in CHME3 cells. All experiments were performed at least three times and data are presented as mean ± SE.
