Figure 2. The knockdown of OGFRP1 inhibited the proliferation in human gastric cancer cells. (A) The expression of OGFRP1 in cells transfected with OGFRP1 specific-siRNA (KD) or control siRNA (NC) was determined by qPCR. CCK8 assay was performed to detect the proliferation of the NC and KD groups in MKN45 (B) and AGS cells (C). OD values were analyzed by a microplate reader at 450nm. (D) The proliferations of MKN45 and AGS cells were further evaluated by clone formation assay. (E) Statistical analysis of colony numbers was performed using the t-test. *P<0.05.
