Identification of key markers for the stages of nonalcoholic fatty liver disease: An integrated bioinformatics analysis and experimental validation

The identification of biomarkers for the early diagnosis of nonalcoholic fatty liver disease (NAFLD) is urgently needed. Here, we aimed to identify NAFLD biomarkers in the early stages of steatosis (SS) and nonalcoholic steatohepatitis (NASH) based on differential gene expression from bioinformatics data.
