Other studies have reported a significantly high expression of PRR11 in a number of types of cancer, such as lung cancer (5,6), ovarian cancer (13), carcinoma of the tongue (18), gastric cancer (9), breast cancer (10,11), hilar cholangiocarcinoma (4), colorectal cancer (12), pancreatic cancer (7) and osteosarcoma (8). This evidence concerns the gene PRR11 and colorectal cancer.
