To investigate the role of STMN1 in FoxM1-mediated cell proliferation in cancer cells, we tested cell proliferation using five cancer cell lines derived from LIHC, GC and CRC, which were infected with control or shFoxM1 lentivirus along with empty vector (EV) or STMN1-overexpressed (STMN1) lentivirus. The gene discussed is STMN1; the disease is cancer.
