Ltd.10.26689/ijgpn.v2i3.8003ArticleClinical and Biological Impact of KRAS Overexpression in Stomach Adenocarcinomahttps://artdesignp.com/journal/IJGPN/2/3/10.26689/ijgpn.v2i3.8003RazaSyed Hussain,AliAkbar2024232024-09-06This study analyzes Kirsten rat sarcoma viral oncogene (KRAS) expression heterogeneity, and biological and clinical relevance in stomach adenocarcinoma (STAD). The study utilized various tools including UALCAN, GEPIA2, Kaplan-Meier (KM) plotter, cBioPortal, STRING, DAVID, and TIMER 2.0 to conduct this analysis.  The results illustrated overexpression of KRAS in STAD and the analysis based on various clinicopathological parameters also verified overexpression of KRAS in STAD. Eventually, this overexpression was linked to poor overall survival (OS) of STAD patients. These results suggested the role of KRAS is involved in the development and progression of STAD. The study also assessed several significant correlations of KRAS expression with promoter methylation tumor purity and immune cell infiltration. Genetic alteration of KRAS revealed to have a strong role in STAD initiation. Gene enrichment analysis highlighted the enrichment of KRAS with various pathways.  In conclusion, the findings illustrated the potential of KRAS as a diagnostic, prognostic, and therapeutic biomarker in STAD.
