Abstract:
Objective To investigate the inhibitory effect of synthetic interferon‐induced transmembrane protein 1(IFITM1) siRNA on the proliferation and migration of human ovarian cancer cell line CP 70 .Methods The siRNA targeted IFITM1 was transfected into CP70 cells by LipofectamineTM 2000 . Expressions of IFITM1 mRNA and protein were examined by qRT‐PCR and Western blot .Plate clone assay and Transwell chamber were used to observe the proliferation and migration of CP 70 cells .Results IFITM1 siRNA significantly inhibited the expression of IFITM1 in human ovarian cancer cell line CP70 at both mRNA and protein levels . The colony formation assay indicated that the clone number was 84 in IFITM1siRNA , which was much fewer than 181 in negative control group and 178 in mock transfection group .The colony‐forming efficiency (CFE) was 42% ,90 .5%and 89% ,respectively .Transwell chamber results showed that the number of migrated cells was 59 ,121 and 126 , respectively ;the siRNA transfection group differed significantly from the other two groups , indicating that downregulated IFITM1 expression greatly inhibited the proliferation and migration of CP 70 cells .Conclusion Knockdown of IFITM1 inhibited the proliferation and migration of CP70 cells .IFITM1 is a potential therapeutic target for human ovarian cancer .
