Li AJ, Dinh TT, Ritter S (2008) Hyperphagia and obesity produced by arcuate injection of NPY-saporin do not require upregulation of lateral hypothalamic orexigenic peptide genes. Peptides 29(10):1732-1739. doi: 10.1016/j.peptides.2008.05.026
Summary: It has already been shown that lesioning NPY receptor-expressing cells in the arcuate nucleus (Arc) and basomedial hypothalamus produces obesity in rats. The authors examined the contribution of orexigenic peptides, orexins, and melanocortin-concentrating hormone to the lesion effects. Rats received bilateral 24 ng injections of NPY-SAP (Cat. #IT-28) into the dorsal border of the Arc. Blank-SAP (Cat. #IT-21) was used as a control. The data suggest that obesity produced by NPY-SAP lesion is different than dietary obesity or obesity associated with leptin or leptin receptor deficiency.
