Remarkably, energy metabolism-related genes such as BCAT1, CTH, PFKM, PRODH, PYCR1, and SLC7A11 stood out among the overlapping genes as the most highly upregulated in both FLC tumors and in FLC cells with increased LINC00473 expression. Here, PYCR1 is linked to fibrolamellar hepatocellular carcinoma.
