However, these bacteria enriched in NC and LG, such as S24_7, Bifidobacteriaceae, and Lactobacillaceae, were negatively correlated with metabolic biomarkers related to NAFLD, including body weight, insulin, hepatic TC, TG, and FFA, and serum levels of ALT and AST. The gene discussed is GPT; the disease is metabolic dysfunction-associated steatotic liver disease.
