SF1 and breast carcinoma: In breast cancer cell lines, when the optimal RG combinations SF1 + TRA2B + THRAP3 + RHOA + QRICH1, SF1 + TRA2B + THRAP3, or THRAP3 + RHOA + QRICH1 were used for normalization, the expression of FAAH was highest in MCF-7 cells, followed by MCF-10A cells, and was least in MDA-MB-231 cells (Fig. 3C).
