The accumulation of lipids caused by increased lipid synthesis is key in the development of obesity, but the molecular mechanisms of increased lipid synthesis remain to be thoroughly studied, especially in the context of aging. In this work, we used in vivo and in vitro models to demonstrate that the long noncoding RNA Lncbate1 contributes to obesity by promoting lipid accumulation. Specifically, Lncbate1 increases lipid synthesis by downregulating the expression of miR-455-5p to increase the expression of the lipid synthesis gene\n                    <jats:italic>ACSS1<\/jats:italic>\n                    .
