TFAM and ovarian cancer: Using the Kaplan‒Meier plotter database (gene expression data and relapse-free and OS information downloaded from GEO, EGA, and TCGA) and GEPIA 2 database (gene expression data and relapse-free and OS information were downloaded from the TCGA), we examined the OS of patients based on high and low expression of TFAM, HSPE1, and CYC1 in ovarian cancer.
