Lu et al. [33] found that CPT1A, KAT2A, SIRT5, and SIRT7 play critical roles in the prognosis of ccRCC, and specifically promote its malignant progression by regulating the infiltration of immune cells and the methylation of RNA N6-methyladenosine (m6A). Here, CPT1A is linked to nonpapillary renal cell carcinoma.
