And further Kaplan-Meier plotter prognostic analysis displayed that overexpression of the major FA anabolic enzymes (FASN, ACC, and SCD) were correlated to poor OS, while overexpression of the FA catabolic enzymes (CPT1A, HADHA, HADHB, and ACAT1) were correlated to favorable OS in ccRCC patients (P<0.05). Here, HADHA is linked to nonpapillary renal cell carcinoma.
