Some studies reported altered DPP4 levels in a number of hepatic diseases, such as chronic C hepatitis [28], hepatocarcinoma and cirrhosis [7]; however, data in literature on circulating DPP4 activity and its concentration in NAFLD/NASH are contrasting [13, 16, 17, 29]. The gene discussed is DPP4; the disease is metabolic dysfunction-associated steatohepatitis.
