Our bodies convert food into energy for all life activities. These metabolic processes allow cells to produce energy (anabolism) and consume energy from nutrients (catabolism). In a recent update out of Kumamoto University in Japan to a continuing research project from the Institute of Molecular Embryology and Genetics (IMEG), researchers found that the LSD1 enzyme suppresses the expression of genes involved in mitochondrial metabolism and the slow-muscle genes that cooperate with them.
