Mechanistically, it is known that the upstream regulatory pathways of CPT1A in gastric cancer include the ERK/PPAR/CPT1A and YAP/CPT1A signaling pathways, as well as the RNA regulatory network, which is directly regulated by microRNAs and circRNAs, and the circ_0024107/miR-5572/miR-6855-5p/CPT1A pathway and other signaling axes composed of microRNAs and circRNAs, by regulating FAO metabolic reprogramming, which in turn promotes lymphatic metastasis of gastric cancer cells [78,79,80,81,82]. Here, PPARA is linked to gastric cancer.
