Expression of lnc-GNAT1-1 in CRC tissues and its association with OS. a Expression of lnc-GNAT1-1 was decreased in liver metastatic tissues than the primary tumor tissues, with an average fold change of 2.22 (P = 0.004). b lnc-GNAT1-1 expression was significantly deregulated in tumor tissues compared with the paired adjacent normal tissues, with an average fold change of 2.04 (P < 0.001). c All the 68 CRC patients were divided into high lnc-GNAT1-1 group (n = 34) and low lnc-GNAT1-1 group (n = 34) according to the median expression level. d Kaplan-Meier analysis showed that low expression of lnc-GNAT1-1 was associated with a poor overall survival of CRC patients (P = 0.001)
