The analysis of the Orai1:Orai2 expression ratio at the protein and transcript level indicates that T47D cells exhibit a greater Orai1/Orai2 expression ratio both at the protein and transcript level (Figure 1g,h; p < 0.001), while SKBR3 and BT20 show an Orai1:Orai2 expression ratio that is significantly smaller than that in non-tumor MCF10A cell (Figure 1g,h; p < 0.05). The gene discussed is ORAI2; the disease is neoplasm.
