Key Points

The aim is to create a prognostic model using mitochondrial-related genes to predict outcomes in ovarian cancer patients.
Constructed the MITO-OC model using ten machine-learning algorithms.
Analyzed data from TCGA, ICGC, and GEO databases.
Identified 241 differentially expressed genes.
Utilized StepCox[forward] and RSF algorithms to optimize the model.
Achieved a C-index of 0.73 for the MITO-OC model.
The model predicts overall survival accurately in patients.
Found a strong correlation between the model and tumor immune infiltration.
Identified CHCHD2 as a significant factor in ovarian cancer and other tumors.

Abstract

Mitochondrial dysfunction drives ovarian cancer (OC) progression. This study constructed a robust prognostic model (MITO-OC) based on mitochondria-related genes using ten machine-learning algorithms on TCGA, ICGC, and GEO data. We identified 241 differentially expressed genes and built the optimal MITO-OC model using StepCoxforward and RSF algorithms (C-index=0.73). The model accurately predicts patient overall survival and strongly correlates with tumor immune infiltration. Furthermore, single-cell and pan-cancer analyses highlighted CHCHD2 as a critical component in OC and other tumors. MITO-OC provides a highly effective, personalized prognostic tool and reveals underlying metabolic mechanisms for OC clinical management.
