To investigate whether MAN2A1-FER gene fusion is widespread among human cancer cell lines, 3 prostate cancer (PC3, DU145, and LNCaP), 4 glioblastoma multiforme (98G, U118, U138, and LN 229), 3 breast cancer (MCF7, MDA-MB231, and MDA-MB330), 4 non-small–cell lung cancer (H358, H1299, H1298, and H522), 2 colon cancer (HCT8 and HCT15), and 1 renal cell carcinoma (293) cell lines were analyzed for MAN2A1-FER mRNA expression. This evidence concerns the gene MAN2A1 and renal cell carcinoma.
