Developing a new cell line model for studying ketogenesis
Fatty liver disease is a global burden for public health, and is commonly associated with obesity and type-2 diabetes. Fatty liver mainly results from an impaired lipid metabolism in livers, showing reduced fatty acid oxidation and ketogenesis. However, the exact mechanism behind this phenomenon is not well understood. Our body begins producing ketone bodies by breaking down fatty acids during extended fasting, which are used as a substitute for glucose. However, one problem with studying ketogenesis is that ketogenesis is not well observed in hepatocytes isolated from an organism. A hepatocyte cell line that could mimic a ketogenic environment is crucial since it is difficult to observe a detailed mechanism of ketogenesis in fatty livers that are not isolated from an organism. Developing a ketogenic hepatocyte cellular model will be a cornerstone for a better mechanistic understanding of the ketogenic pathway, its regulators, and how it gets dysfunctional in fatty livers.
