Analysis of MCF10A and human breast cancer cells (MDAMB231, BT474, MCF7, T47D, and MDAMB436) by qRT-PCR and Western blotting showed that T47D and MCF7 cells had the highest VPS28 expression levels compared with the other cell lines tested (Figures 3A,B, *p < 0.05 and **p < 0.01). Here, VPS28 is linked to breast cancer.
