Fasting and highfat diet alter histone deacetylase expression in the<br />

medial hypothalamus<br />

<br />

<br />

Increasing attention is now being given to the epigenetic regulation of animal<br />

and human behaviors including the stress response and drug addiction. Histone<br />

deacetylases HDACs are involved in the epigenetic control of gene expression<br />

and alter behavior in response to a variety of environmental factors. In response<br />

to fasting and highfat diets, the expression of both orexigenic and anorexigenic<br />

neuropeptides change in the medial hypothalamus, a crucial region for feeding<br />

behavior and body weight homeostasis. However, the mechanism by which gene<br />

expression is modulated in the medial hypothalamus remains to be clarified.<br />

Here, we examined the expression of HDAC family members in the medial<br />

hypothalamus of mice in response to either fasting or a highfat diet. In response<br />

to fasting, HDAC3 and 4 expression levels increased while HDAC10 and<br />

11 levels decreased. Four weeks on a highfat diet resulted in the increased<br />

expression of HDAC5 and 8. Therefore, HDACs may be implicated in altered<br />

gene expression profiles in the medial hypothalamus under different metabolic<br />

states.<br />
