Figure 6. (A) Protein expression profiles of ARPC1A in the knockout cell lines when compared to the control group. (B) CCK-8 assays: cell proliferation is lesser in the ARPC1A cells in the knockout cell lines than normal cells. (C, D) Flow cytometry: the apoptosis rate is lower in the knockout cell lines than in the normal cell lines. (E) MAPK signaling pathway accompanied by the downregulation of p-ERK1/2 in the knockout group was more evident than in the control group.
