We next verified the expression of ITM2A in a panel of human breast cancer cell lines, including MCF-7, MDA-MB-231, MDA-MB-468, BT474 and SKBR-3, and the normal breast epithelial cell line Hs578Bst, as well as the human embryonic kidney cell line HEK293T. This evidence concerns the gene ITM2A and breast carcinoma.
