ESR1 and triple-negative breast carcinoma: Consistent with the previous study by Aydar and coworkers [31], Western blot analysis of whole cell lysates from the non-tumoral breast MCF10A cell line, the ER+ and triple negative breast cancer cell lines MCF7 and MDA-MB-231, respectively, with a specific anti-human TRPC6 antibody revealed that the expression of this protein is relatively low in the non-tumoral cell line (Figure 1).
