A saturated fatty acid-rich diet enhances hepatic lipogenesis and tumorigenesis in HCV core gene transgenic mice.

ABSTRACT: Previous studies suggested that high consumption of saturated fatty acid (SFA) is a risk factor for liver cancer. However, it remains unclear how dietary SFA affects liver tumorigenesis. This study aimed to investigate the impact of a SFA-rich diet on hepatic tumorigenesis using hepatitis C virus core gene transgenic (HCVcpTg) mice that spontaneously developed hepatic steatosis and tumors with aging. Male HCVcpTg mice were treated for 15 months with a purified control diet or SFA-rich diet prepared by replacing soybean oil in the control diet with hydrogenated coconut oil, and phenotypic changes were assessed. In this special diet, almost all dietary fatty acids were SFA. Long-term feeding of SFA-rich diet to HCVcpTg mice increased hepatic steatosis, liver dysfunction, and the prevalence o
