Limb‐bud and heart development (LBH) contributes to glioma progression in vitro and in vivo

Glioma is the predominant brain malignancy and is correlated with high mortality and severe morbidity. The transcription factor limb‐bud and heart (LBH) has been reported to be involved in the development of several cancers, although its role in glioma development remains elusive. Here, we examined the effect of LBH on glioma progression. The expression of LBH was increased in glioma samples from The Cancer Genome Atlas database, and upregulation of LBH was observed to be correlated with the poor survival of glioma patients. We also report that expression of LBH was elevated in clinical glioma tissues compared to adjacent normal tissues, and was also enhanced in glioma cell lines. LBH promotes proliferation and inhibits cell cycle arrest and apoptosis in glioma cells. In addition, LBH increased the migration and invasion of glioma cells in vitro. Moreover, tumorigenicity analysis revealed that LBH could promote the tumor growth of glioma cells in vivo. In conclusion, our findings suggest that LBH contributes to glioma progression in vitro and in vivo. Our findings provide new insights into the mechanism by which LBH promotes the development of glioma, improving our understanding of the correlation between LBH with cancer. LBH may have potential as a target for glioma therapy.
