Figure 1. Expression of PSMC3IP and EPSTI1 in normal and breast cancer cell lines.

Figure 1

We inspected the endogenous expression of PSMC3IP (A) and EPSTI1 (B) in two types of breast cancer cell lines, MDA-MB-231 and MCF-7, as compared to a normal breast epithelial cell line, MCF-10A. Estimated protein levels based on densitometry (right) of the immunoblots (left) show a PSMC3IP 19- and 15-fold expression in MDA-MB-231 and MCF-7 cells, while EPSTI1 only shows 1.9- and 1.3-fold in each cell line, respectively. Protein levels were normalized based on the loading control protein β-actin. (*P <0.05, **P<0.01, ***P <0.001 vs MCF-10A cells).
