Research Abstract

In BMM of Elovl6 KO, it is promotion of proliferation and differentiation. In addition, activation of the bone resorption function in mature osteoclasts was observed. At this time, there was no change with a typical differentiation marker, but expression of the gene relevant to a cell cycle was increasing. Furthermore, proliferation and differentiation were accelerating also in osteoblasts. Therefore, the composition change of fatty acid affects energy metabolism and a cell cycle, and is considered to adjust proliferation and differentiation.
