Environmental factors such as nutritional state may act on the epigenome that consequently contributes to the metabolic adaptation of cells and the organisms. The lysine-specific demethylase-1 (LSD1) is a unique nuclear protein that utilizes flavin adenosine dinucleotide (FAD) as a cofactor. Here we show that LSD1 epigenetically regulates energy-expenditure(More)
The way in which energy is used in cells is determined under the influence of environmental factors such as nutritional availability. Metabolic adaptation is mainly achieved through the modulation of metabolic gene expression, and may also involve epigenetic mechanisms that enable long-term regulation. Recent studies have identified that nutrients and their(More)
The hallmark of most cancer cells is the metabolic shift from mitochondrial to glycolytic metabolism for adapting to the surrounding environment. Although epigenetic modification is intimately linked to cancer, the molecular mechanism, by which epigenetic factors regulate cancer metabolism, is poorly understood. Here, we show that lysine-specific(More)
Cells link environmental fluctuations, such as nutrition, to metabolic remodeling. Epigenetic factors are thought to be involved in such cellular processes, but the molecular basis remains unclear. Here we report that the lysine-specific demethylase 2 (LSD2) suppresses the flux and metabolism of lipids to maintain the energy balance in hepatic cells. Using(More)
The patient was a woman, aged 69, diagnosed with acute pancreatitis by a local physician; simultaneously, with US, a low-echo tumor was indicated in the pancreas' uncinate process. Diagnosis was made of acute pancreatitis resulting from a pancreatic IPMN, and the patient was referred. Ultrasound showed hypoechoic tumor images accompanied by posterior echo(More)
