Examining Copper-dependent Cell Death-associated Genes in Relation to Immune Cell Presence and Disease Outcomes in Stomach Adenocarcinoma

Cuproptosis represents a novel class of cell death modality different from other regulated cell death pathways. However, the role of genes involved in copper-mediated cell death within the tumor microenvironment of gastric adenocarcinoma remains to be elucidated. This study utilized R programming to classify unprocessed information from TCGA and GEO repositories of individuals with stomach adenocarcinoma. Associations among various patient clusters, clinical factors, immune cell infiltration attributes, and the tumor microenvironment were assessed. Graphical displays were generated to improve the practical utility of copper-dependent cell death gene scores and evaluate patient outcome probabilities. This work sought to examine the links between copper-mediated cell death and molecular traits, immune cell presence in the tumor, patient outcomes, and therapeutic approaches. A copper-dependent cell death gene score was developed to predict patient survival and assess its prognostic value in stomach adenocarcinoma. Results revealed that reduced copper-mediated cell death scores correlated with increased tumor mutations, immune responsiveness, and greater survival rates, while elevated scores were linked to suppressed immunity and enhanced tumor microenvironment signaling. This study additionally determined prognostic factors related to copper-dependent cell death genes in stomach adenocarcinoma, which could elucidate qualities of the tumor surroundings and aid in the development of enhanced immunotherapeutic approaches.
