Rab27A expression was upregulated in MDA-MB-231 mammospheres. (A) Representative images of mammospheres and adherent cells of the breast cancer cell line MDA-MB-231. (B) Reverse transcription-quantitative polymerase chain reaction analysis revealed upregulation of Rab27A expression in MDA-MB-231 mammospheres. (C) Western blot analysis demonstrated that Rab27A expression was higher in MDA-MB-231 sphere cells than in adherent cells. Data here presented as the mean ± standard deviation and experiments were performed in triplicates. *P<0.05 vs. control.
