PCAT1 and colorectal carcinoma: For this, they analyzed the expression levels of PCAT-1 by Real Time qPCR in 108 CRC tumors and 81 matched controls (selected from 2003 to 2007), and observed that PCAT-1 was frequently up-regulated in CRC tissues compared with normal adjacent tissue, and that PCAT-1 was able to stratify overall survival and correlated with distant metastasis in CRC patients.
