RRSM is a potential prognostic predictor for STS and lays a foundation for early intervention of high-risk STS patients. The expression of genes FZD7, ITPKA, and PRKAG1 may guide STS treatment decisions.

COL6A3 (Collagen Type VI Alpha 3 Chain) • PRKAG1 (Protein Kinase AMP-Activated Non-Catalytic Subunit Gamma 1) • FZD7 (Frizzled Class Receptor 7) • ITPKA (Inositol-Trisphosphate 3-Kinase A)
This study elucidates the oncogenic role of the MALAT1/miR-383-5p/PRKAG1 axis in HCC, demonstrating that PRKAG1 promotes tumor progression by regulating cell proliferation, the immune microenvironment, and key signaling pathways. These findings provide potential novel targets for HCC prognosis assessment and targeted therapy.
In vitro experiments indicated that PRKAG1 and B3GAT3 were upregulated, enhancing glycolysis and promoting HCC cell proliferation and migration. The IGRPS, based on immune- and glycolysis-related genes, effectively predicted prognosis and immunotherapy responses in HCC patients.
This led to a metabolic shift towards “Warburg” effect with an elevated extracellular acidification rate (ECAR) to oxygen consumption rate (OCR) ratio, thereby promoting a gastric tumorigenic phenotype. Conclusion : ALKBH1-driven DNA 6mA demethylation in GC plays an oncogenic role in GC by repressing NRF1-mediated transcription of AMPK targets, which promotes a “Warburg” phenotype and tumorigenesis.
