We found high levels of FAM171A1 in the basal-type TNBC cell lines such as MDA-MB-231, SUM149, SUM159, BT549, HCC1937, and Hs-578T as compared to non-TNBC breast cancer cell lines such as MCF-7, T47D, ZR-75, and SKBR3 as well as normal mammary epithelial cell line, HMEC (Fig. 1a–c, Supplementary 4A, B). The gene discussed is FAM171A1; the disease is breast carcinoma.
