Article Synopsis
- MeCP2 is linked to neurodevelopmental disorders like Rett Syndrome and contributes to obesity and overeating when knocked out in the central nervous system.
- Mice lacking MeCP2 specifically in POMC neurons show a heightened preference for high-fat diets but do not exhibit increased motivation for food compared to normal mice.
- These findings reveal that losing MeCP2 in POMC neurons affects food reward perception and leads to changes in hormones related to body weight and stress.

Article Synopsis
- Obesity is influenced by multiple factors, including genetic, environmental, and endocrine elements, with rare monogenic forms necessitating the study of other contributing mechanisms.
- Methyl-Cp-G binding protein 2 (MeCP2) plays a role in obesity by binding to DNA and affecting gene transcription, with past studies indicating its disruption leads to obesity in mice.
- In a mouse model of diet-induced obesity, perinatal exposure to a high-fat diet significantly reduced MeCP2 expression in the hypothalamus, showing sex-specific patterns in expression changes, while suggesting that high-fat diet exposure in adulthood may affect different mechanisms unrelated to MeCP2.
