YAP1 and gastric cancer: A recent interesting study uncovered that a microprotein (pep-AKR1C2) encoded by exosomal lncAKR1C2 derived from GC cells can upregulate the expression of CPT1A in lymphatic endothelial cells via regulating YAP phosphorylation, thus promoting gastric cancer lymph node metastasis by enhancing FAO and ATP production [165].
