The LEP gene codes for an anorexigenic hormone. Interestingly, breastfeeding has been shown to alter methylation of the promoter of this gene, leading to increased LEP expression. What is likely happening in response to breastfeeding? - Breastfeeding decreases the methylation of the promoter of the LEP gene, increasing the spacing between nucleosomes.
