The role of NAFLD in extrahepatic malignancies: The importance of ruling out the effect of obesity

Progress and challenges in the prevention and control of nonalcoholic fatty liver disease

Nonalcoholic fatty liver disease (NAFLD) is rapidly becoming the most common liver disease worldwide. Individuals with NAFLD have a high frequency of developing progressive liver disease and metabolism-related comorbidities, which result from of a lack of awareness and poor surveillance of the disease and a paucity of approved and effective therapies. Managing the complications of NAFLD has already begun to place a tremendous burden on health-care systems. Although efforts to identify effective therapies are underway, the lack of validated preclinical NAFLD models that represent the biology and outcomes of human disease remains a major barrier. This review summarizes the characteristics and prevalence of the disease and the status of our understanding of its mechanisms and potential therapeutic targets.
