Pseudogene INTS6P1 regulates its cognate gene INTS6 through competitive binding of miR-17-5p in hepatocellular carcinoma [mRNA, lncRNA]. Homo sapiens

To identify the novel tumor suppressors in hepatocellular carcinoma (HCC), we have employed whole genome microarray expression profiling as a discovery platform in HCC and paired normal liver tissues to identify genes which down-regulated in HCC. Among which, INTS6 and its pseudogene, namely INTS6P1, were found to be dramatically down-regulated in HCC. The down-regulated expression of INTS6 and INTS6P1 in HCC was further confirmed by real-time PCR. Overall design: RNA was extracted from 3 pairs of HCC and normal liver tissue harvested from patients to undergo microarray study.
