Recent studies have focused on the association between primary osteoarthritis and dyslipidemia. STR/Ort mice have unique characteristics including osteoarthritis and hyperlipidemia, and may be a useful model for investigating the effect of dyslipidemia on the underlying mechanism of primary osteoarthritis. However, little is known about the hyperlipidemic properties of STR/Ort mice. In this study we investigated hyperlipidemia and lipotoxicity in STR/Ort mice. STR/Ort mice have human hyperlipidemic patient-like symptoms such as hypercholesteremia, hypertriglyceridemia, hyperinsulinemia, insulin resistance, dysregulation of NEFA, and low serum adiponectin. Excess triglyceride accumulation in the liver of STR/Ort mice was not observed even when they exhibited hyperinsulinemia. This information may be useful for researchers investigating lipid metabolism and primary osteoarthritis using STR/Ort mice.
