Abstract
Objective: To explore the regulatory mechanism of NUDT5 in glioblastoma multiforme (GBM). Methods: GEPIA database was used to predict the expressions of NUDT5 and tripartite motif family proteins 47 (TRIM47) in GBM patients. RT-qPCR and Western blot analyses were performed to examine NUDT5 expression in GBM cells. LN-229 cell proliferation, migration as well as invasion were estimated by CCK-8, colony formation, wound healing, and Transwell assays following interference with NUDT5. ECAR assay, L-lactic acid kit, glucose detection kit, and ATP detection kit were applied for the detection of glycolysis-related indexes. Co-immunoprecipitation experiment was carried out to verify the relationship between NUDT5 and TRIM47. Results: GEPIA database showed that NUDT5 expression was significantly increased in GBM patients. Inhibiting the expression of NUDT5 in GBM cells significantly suppressed the viability, proliferation, invasion, migration, and glycolysis of GBM cells. Moreover, TRIM47 was highly expressed in GBM cells and interacted with NUDT5. Overexpression of TRIM47 partially reversed the inhibitory effect of NUDT5 downregulation on the proliferation, metastasis, and glycolysis of GBM cells. Conclusions: NUDT5 promotes the growth, metastasis, and Warburg effect of GBM cells by upregulating TRIM47. Both NUDT5 and TRIM47 can be used as targets for GMB treatment.
