HIF-1α facilitates glioma proliferation and invasion by activating pyroptosis signaling axis

中华神经外科杂志(英文) 2024年第2期10卷 1-9页

作者： wang Xin-Wei Fu Hao Zhang ya-Min The First Central Clinical School Tianjin Medical University Tianjin China Department of General Medicine Characteristic Medical Center of PAP Tianjin China

Background HIF-1α is thought to be a novel regulator which contributes to carcinogenesis. However, the mechanism underlying the effect of HIF-1α in gliomas remains largely *** In the research, we demonstrate that HIF-lα mRNA and protein levels are elevated in glioma cells. The colony formation assays, transwell assays, and wound-healing assays showed that overexpression of HIF-1α promoted proliferation and invasion of glioma *** Overexpression of HIF-lα also increased the expression of inflammatory factors related to pyrolysis (TNF-α, IL-10, and IL-1β) and protein related to pyrolysis signal pathway (NLRP3, ASC, caspase-1, GSDMD, and GSDME).Conclusions Therefore, we speculate that HIF-1α promotes the proliferation and invasion of glial cells by regulating pyrolysis pathway. These results might provide a novel strategy and target for treatment of glioma.
