Abstract/OtherAbstract:
Growing evidence indicates that some tumor suppressive miRNAs are subject to epigenetic modifications during carcinogenesis. Here, we found that a large miRNA cluster of C19MC was upregulated in HCC cells after combined treatment with DNA methylation inhibitor and histone deacetylase inhibitor. MiR-517a and miR-517c were strikingly different from the remaining 41 miRNAs in C19MC. Ectopic expression of MiR-517a and miR-517c inhibited cell proliferation by blocking G2/M transition, whereas down-regulation of miR-517a and miR-517c facilitated cell growth. We further showed Pyk2 is a target of miR-517a and miR-517c and both the miRNAs are downregulated in HCC samples. These data collectively suggest that down-regulation of both miR-517a and miR-517c contribute to HCC development through regulating Pyk2.
