Purpose: We previously developed medaka non-alcoholic steatohepatitis (NASH) model. The model showed similar histology with human NASH so we analyzed the effect of drug using medaka NASH activity score (MNAS). In this study we analyzed the effect of ezetimibe, a small intestine cholesterol transporter inhibitor, on NASH.

We used the NASH activity score (NAS) developed in humans to assess the histology of the medaka NASH model and found that NAS increased with time. Further, TUNEL-positive apoptosis hepatocytes were found in the medaka NASH model.

We have developed a NASH model in the ricefish medaka (Oryzias latipes), which is based on feeding the fish a high-fat diet (HFD). Medaka that are fed a HFD (HFD-medaka) exhibited hyperlipidemia and hyperglycemia, and histological examination of the liver revealed ballooning degeneration.
