Glutamine metabolism promotes migration, invasion, and cytoskeleton morphology by up-regulating ARPC1A expression in PCa cells. A GSEA analysis revealed a significant positive association between high ARPC1A expression and glutamine metabolism. B Proposed model describing the roles of glutamine metabolism and ARPC1A in PCa. C–E ARPC1A expression, cytoskeletal morphology, and the migration and invasion potential of PC-3 cells cultured in different types of media. *: P < 0.05; ns no statistical significance, Gln glutamine, Glc Glucose, DKG dimethyl α-ketoglutarate. F–H ARPC1A expression, cytoskeletal morphology, and the migration and invasion potential of PC-3 cells under the indicated treatment conditions. *: P < 0.05; ns no statistical significance
