Transcriptomic analysis of the hypothalamic paraventricular and the arcuate nucleus of NNAT null mice. Transcriptomic analysis of the hypothalamic paraventricular and the arcuate nucleus of NNAT null mice

Neuronatin (Nnat) has previously been reported to be part of a network of imprinted genes. Disruption of neuronatin results in an unusual phenotype of a bimodal body weight.In order to understand at the molecular level how the Nnat deficiency could contribute to the hypervariable phenotypes seen, we performed RNA sequencing from laser-capture micro dissected paraventricular nucleus (PVN) and arcuate nucleus (ARC) and compared the transcriptome between Nnat+/-p mice and their Nnat+/+ littermates in different feeding conditions. We performed an analysis of three subgroups: Nnat+/+ (all non-obese), Nnat+/-p non-obese, and Nnat+/-p obese mice and combined two approaches to identify differences in hypothalamic gene expression between subgroups Overall design: Gene expression analysis between wild-type and NNAT null mice
