The expression of CTHRC1 in M21 cells. A. The mRNA expression of CTHRC1 in M21 cells transfected with negative control (NC) and miR155 vectors or treated with miR155 inhibitor were determined by RT-PCR. B. The protein expression of CTHRC1 in M21 cells transfected with NC and miR155 vectors by WB. *indicates P<0.05.
