The results showed that PROZ was unrelated to the type of the underlying disease of HCC; there was no difference in the expression of PROZ in alcoholic liver disease, Hepatitis B Virus (HBV), Hepatitis B Virus (HCV) and Nonalcoholic fatty liver disease (NAFLD)-related liver cancer (Figure 2A). Here, PROZ is linked to metabolic dysfunction-associated steatotic liver disease.
