Research Abstract	Medaka with HFD showed high NASH activity score (NAS), suggesting that circadian rhythm change is related to NASH progression. The light system is closely related with chronic inflammation by light stimulation. Collaboration with Oklahoma university, we found that NASH medaka developed diabetic nephropathy. These data showedmedaka fish model is useful to analyze the mechanism of NASH and nephropathyand to develop a new chronotherapy.
