HSD17B14 and metabolic dysfunction-associated steatotic liver disease: Four intersection genes were accordingly identified as key genes involved in the regulation of the differential intestinal flora in NAFLD: colony-stimulating factor 2 receptor β (CSF2RB), fucosyltransferase 2 (FUT2), 17-beta-hydroxysteroid dehydrogenase 14 (HSD17B14), and microtubule affinity-regulated kinase 3 (MARK3) (Figure 6E).
