MTOR and breast carcinoma: To confirm the association of Aur-A and mTOR in the TNBC subtype, we first detected the expression of the two proteins and other related proteins in five TNBC cell lines (BT-549, BT-20, MDA-MB-435, MDA-MB-231, and MDA-MB-468), along with four non-TNBC breast cancer cell lines (MCF-7, MDA-MB-453, T47D, and BT-474) and a noncancerous breast epithelial cell line (MCF-10A) as controls.
