Figure 4. CASC21 affects proliferation related proteins expression and promotes CRC growth in vivo. (A) EdU assays were used to determine the cell proliferate ability of CASC21 siRNAs transfected cells. (B) Cell proliferation related proteins cyclin D1, and cyclin D2, were detected by western blot after CASC21 silencing. (C) Representative images of tumors formed in nude mice from negative control vector, sh-CASC21 vector and CASC21 overexpression groups, and the tumor volume growth curves after injections in different groups. Representative images for HE-staining and Ki67 immunostaining of tumor samples from different groups. All data represent mean ± SEM (n = 3-6). ^*P < 0.05 and ^**P < 0.01.
