G6PD and neoplasm: We also compared mRNA levels of previously known tumor-associated genes such as Afp (α-fetoprotein [AFP]), G6pd (glucose-6-phosphate dehydrogenase [G6PD]), Prom1 (CD133), and Cxcl1 (chemokine [C-X-C motif] ligand 1 [CXCL1] or keratinocyte-derived chemokine) in tumorous and non-tumorous lesions in the liver of MC4R-KO mice.
