Genes that prevent fat breakdown were more prevalent in the fat tissues of overweight mice than in their leaner counterparts, a study in PLoS One revealed. The researchers found that overweight offspring of an overweight mouse and a lean mouse also had these genes, suggesting a hereditary pattern in weight gain. "If we can identify the genes and proteins that are controlling how fat we get, we may be able to target them with medicines to try and target the obese or the consequences of obesity," one researcher said.
