Abstract
miR-152 and lncRNA H19 have been frequently implicated in various cellular processes including cell proliferation, invasion, angiogenesis, and apoptosis. However, the interaction between miR-152 and H19 in glioma
has never been reported. RT-qPCR was used to examine the expression of miR-152 and H19 in human glioma
cell lines and normal human astrocytes (NHAs). The interaction between miR-152 and lncRNA H19 was
assessed by dual-luciferase reporter assay. MTT assay and Transwell invasion assay were used to determine
the proliferation and invasion of U251 and U87 cells. A xenograft tumor experiment was performed to confirm
the role of H19 in vivo. The results showed that H19 expression was upregulated and miR-152 expression was
downregulated in human glioma cell lines. H19 downregulation or miR-152 upregulation suppressed glioma
cell proliferation and invasion in vitro. Moreover, H19 and miR-152 directly regulated each other. Furthermore,
decreased miR-152 expression alleviated si-H19-induced inhibitory effects on proliferation and invasion in
glioma cells. As expected, H19 silencing hindered glioma growth in vivo. Taken together, H19 promoted
glioma cell proliferation and invasion by negatively regulating miR-152 expression, providing evidence for the
potential application of H19 as a biomarker and therapy target for glioma.
