The effect of RPLP1 expression on cell behavior. a MDA-MB-231 cells were transfected with the control vector, RPLP1 shRNA vector, or RPLP1 expression vector. The expression of RPLP1 was detected by Western blot. b Brdu assays showing cell proliferation in respect to RPLP1 expression. c The clone formation assay shows that changes in RPLP1 expression did not affect cell clone formation abilities. d Matrigel transwell assay shows cell invasion when RPLP1 is overexpressed or RPLP1 expression is suppressed in MDA-MB-231 and MDA-MB-468 cells. Representative images are shown.*^,#P < 0.05 compared to control vector
