Expression of Orai and TRPC members in breast stem cells and breast cancer stem cells derived from the MCF10A, MCF7, SKBR3 and MDA-MB-231 cell lines. (A) RT-qPCR expression analysis of Orai1, Orai2, Orai3, TRPC1, TRPC3 and TRPC6 mRNA transcripts in BSC derived from the MCF10A cell line and BCSC derived from the MCF7, SKBR3 and MDA-MB-231 cell lines. Values were normalized to GAPDH expression and represented as mean expression relative to MCF10A-derived BCSC ± S.E.M.; n = 6. (B) Whole cell lysates from non-stem cells and stem cells derived from MCF10A, MCF7, SKBR3 and MDA-MB-231 cell lines were subjected to 10% SDS-PAGE and Western blotting with specific anti-Orai1 antibody, as indicated. Blots were reprobed with anti-β-actin antibody for protein loading control. Bar graph represents Orai1 expression presented as mean ± SEM. Data were statistically analyzed using Kruskal–Wallis test with multiple comparisons (Dunn´s test). **p < 0.01 and ****p < 0.0001.
