Further, the miRNA-target gene network analysis displayed that the deleted in liver cancer (DLC-1) gene, an important negative regulator for cell motility, was potentially targeted by several differentially expressed miRNAs in HBc-introduced cells.
The deleted in liver cancer (DLC-1) gene at chromosome 8p21-22 is altered mainly by genomic deletion or aberrant promoter methylation in a large number of human cancers such as breast, liver, colon and prostate and is known to have an inhibitory effect on breast and liver tumor cell growth.
The DLC-1 gene encoding a regulator of the Rho family of small GTPases is altered in breast, prostate, colon, and liver cancer and has several characteristics of a tumor suppressor gene.
We investigated the expression and deletion of DLC-1 (frequently deleted in liver cancer gene), first reported in 1998 and having a high homology with rat p122RhoGAP in hepatocellular carcinoma (HCC).
