Effects of silencing UHMK1 on proliferation,migration and invasion in breast cancer cells

Purpose To study the effect of silencing UHMK1 expression of breast cancer cells on the proliferation,migration and invasion in vitro.Methods Short hairpin(shRNA)was used to interfere with the expression of UHMK1 in breast cancer cell line MDA-MB-231.qRT-PCR and Western blot were used to detect the interference efficiency of shRNA.MTT assay was used to detect the effect on cell viability.The change of cell proliferation ability was detected by clone formation assay.Transwell assay detected effect on cell migration and invasion.Results UHMK1-shRNA significantly interfered with UHMK1 expression in breast cancer cells MDA-MB-231(P<0.01).Compared with the control group Plko.1,the interference of UHMK1 expression significantly downregulated the capacity of proliferation,migration and invasion in breast cancer cell line MDA-MB-231(P<0.01).Conclusion UHMK1 expression may be involved in the regulation of biological behavior of breast cancer.
