We measured the expression of LOX and LOXL1-4 in a total of 10 human breast cancer cell (hBCC) lines that are classified as either luminal (MCF-7, BT-474), HER2 (MDA-MB-453, SK-BR3, HCC1954), or TN (BT-549, MDA-MB-157, MDA-MB-231, MDA-MB-468, HCC1937) subtype, as well as in normal breast epithelial cells (MCF-10A). Here, LOX is linked to breast carcinoma.
