PPARA and gastric cancer: Interestingly, integrative analysis of complex cancer genomics and clinical profiles using the cBioPortal 24, we found in two separate databases (TCGA Provisional and TCGA PanCancer Atlas) that the expression of CPT1A was positively correlated with PPARα (Figure 5E), further suggesting that PPARα may be a transcription factor of CPT1A in gastric cancer.
