Investigating the dysregulation of genes associated with glucose and lipid metabolism in gastric cancer and their influence on immunity and prognosis

Gastric cancer (GC) is one of the most prevalent malignant tumors globally, characterized by a high mortality rate. The disruption of glucose and lipid metabolism plays a critical role in the occurrence and progression of GC. By integrating single-cell and bulk RNA sequencing data, we identified 135 marker genes associated with glucose and lipid metabolism in GC. Building on this, we conducted prognosis and immune-related analyses, followed by cluster analysis that depicted various molecular subtypes, elucidating their distinct molecular mechanisms and treatment strategies. This includes examining how genes related to glucose and lipid metabolism influence GC prognosis through immune pathways. Additionally, we established a clinical prognostic model characterized by THRAP3, KLF5, and ABCA1. Notably, the core target gene ABCA1 may serve as a prognostic and immunotherapy biomarker for GC.
