ABSTRACT
Purpose To investigate the effect of silencing of CD98hc on proliferation,migration and invasion of MDA-MB-231 breast cancer cells.Methods RNA interfere technology was used to silence CD98hc in MDA-MB-231 cells.MDA-MB-231 cells (CD98hc-shRNA) with stable low expression of CD98hc and Vector control was obtained.Western blot and qRT-PCR were used to verify the down-regulation of CD98hc.MTT assay was used to test the cell proliferation.Transwell migration and invasion experiment were used to assay cell migration and invasion.Results The expression levels of CD98hc was down-regulated by CD98hc-shRNA in the MDA-MB-231 breast cancer cells.Compared to that of blank cells (0.706 ± 0.013),vector control (0.724 ± 0.018),the cell proliferation potency of CD98hc-shRNA cells (0.580-0.035) was significantly inhibited (P ＜ 0.05),and the cell migration and invasion potency also were inhibited (P ＜ 0.05),there is on significant different between blank cells and vector control (P ＜ 0.05).Conclusion CD98hc might be involved in the regulation of breast cancer cell biological behaviors.
