KRAS and metabolic dysfunction-associated steatotic liver disease: HDL-bound miR-17-5p, HDL-bound miR-532-5p, HDL-bound miR-143-3p and HDL-bound miR-185-5p were involved in the Ras signalling pathway, and KRAS could alleviate high-fat diet-induced non-alcoholic fatty liver disease by inhibiting the synthesis and promoting beta-oxidation of fatty acids [43].
