We examined GABRP protein levels in five breast cancer cell lines and similar to the mRNA expression data, we found that both TNBC (HCC1143, MDA-MB-468, MDA-MB-231) and non-TNBC (SKBR3 and BT-474) cells express comparable GABRP protein levels (Fig. 2A). This evidence concerns the gene GABRP and breast carcinoma.
