Abstract:
This study aimed to check the biological functions and uncover the mechanism of armadillo repeat protein C10 (ARMC10) in glioblastoma (GBM). The expression and potential mechanisms of ARMC10 in GBM were analyzed by bioinformatics analysis. In GBM cells, function-loss experiments were used to evaluate the influences of ARMC10 on cell proliferation, cell invasion, lipid levels, and cell migration by colony formation assay, 5-ethynyl-2'-deoxyuridine staining, cell counting kit-8 assay, transwell assay, BODIPY staining, and wound healing assay. Mouse xenograft models were constructed to validate the influences of ARMC10 in vivo. ARMC10 levels in GBM were upregulated, and patients with low ARMC10 levels displayed a better prognosis. ARMC10 knockdown resulted in a decrease of GBM cell invasion, migration, and proliferation. GSEA showed that ARMC10 was positively associated with the Notch pathway and fatty acid metabolism. ARMC10 knockdown reduced the levels of triglyceride, cholesterol, and lipid, and inhibited the expression of proteins related to fatty acid metabolism and Notch pathway. Moreover, notch receptor 1 (Notch1) overexpression reversed the inhibition of cell proliferation, fatty acid metabolism, and invasion induced by ARMC10 knockdown. In vivo, ARMC10 knockdown suppressed tumor growth. RMC10 knockdown suppressed GBM malignant progression, which had a bearing on Notch pathway.
