Here, we studied the Lynx1 expression in human cells of epithelial origin (normal oral keratinocytes Het-1A, embryonic kidney cells HEK-293T, epidermoid carcinoma A431, breast adenocarcinoma MCF-7, lung adenocarcinoma A549 and colon carcinoma HT-29). The gene discussed is LYNX1; the disease is colon carcinoma.
