英文摘要 | Ciliary neurotrophic factor receptor a subunit (CNTFR alpha) and CNTF play important roles in neuron survival, glial differentiation and brain tumor growth. However, the molecular mechanisms of CNTFR alpha regulation and its clinical significance in glioma remain largely unknown. Here, we found CNTFR alpha was overexpressed in lower grade gliomas (LGG) compared with glioblastoma (GBM) and normal brain specimens in TCGA datasets and in an independent cohort. Bioinformatics analysis revealed a CpG shore of the CNTFR alpha gene regulated its mRNA expression in TCGA datasets. This observation was further validated with clinical specimens and functionally verified using demethylating agents. Additionally, we observed that independent of IDH mutation status, methylation of CNTFR alpha was significantly correlated with down-regulated CNTFR alpha gene expression and longer LGG patient survival. Interestingly, combination of CNTFR alpha methylation and IDH mutation significantly (p < 0.05) improved the prognostic prediction in LGG patients. Furthermore, the role of CNTFR alpha in glioma proliferation and apoptosis through the PI3K/AKT pathways was demonstrated by supplementation with exogenous CNTF in vitro and siRNA knockdown in vivo. Our study demonstrated that hypomethylation leading to CNTFR alpha up-regulation, together with autocrine expression of CNTF, was involved in glioma growth regulation. Importantly, DNA methylation of CNTFR alpha might serve as a potential epigenetic theranostic target for LGG patients. |
