During the non-breeding period, kisspeptin expression in the arcuate nucleus is markedly reduced.

Prominent vascular permeability of low- and high-molecular-mass tracers was also observed in the arcuate nucleus.

Seven-day running wheel access also results in elevated arcuate nucleus and DMH neuropeptide Y gene expression.

Bilateral leptin injections into the rat arcuate nucleus produced long-lasting suppression of meal size and total chow intake.

These results provide new insights into the mechanism by which ghrelin regulates voluntary activity independent of arcuate nucleus neurons.

A significant increase in phosphorylated STAT5 was detected in the arcuate nucleus of female rats compared with same-sex controls.

However, no differences in NPY projections to kisspeptin neurons in the arcuate nucleus were detected between HG and LG heifers.

Hypothalamic arcuate nucleus peptide mRNA expression in OLETF rats is appropriate to their obesity and is normalized by pair feeding.

In retrograde tracing experiments, a small percentage of arcuate nucleus POMC neurons was found to project to the dorsal vagal complex.

Hypocretin cells innervate the mediobasal hypothalamus where they can potentially influence the activity of specific cell populations within the arcuate nucleus.

Within the hypothalamus, the level of receptor mRNA was low in most nuclei with a somewhat higher level in the arcuate nucleus.

Heifers that gained BW at a higher rate exhibited greater circulating concentrations of leptin and reduced overall NPY expression in the arcuate nucleus.

Neuron-specific tracing from the arcuate nucleus with a Cre-inducible tract-tracing adenovirus in POMC-Cre mice showed the presence of labeled axons in the NTS.

SORCS1 and SORCS3 are two related sorting receptors expressed in neurons of the arcuate nucleus of the hypothalamus.

Sensitization to cocaine or amphetamine was spared in monosodium glutamate-pre-treated animals, although the lesion of arcuate nucleus reduced the sensitivity of mice to cocaine.

Different groups of mice were used to assay blood ethanol levels and to evaluate the effect of arcuate nucleus lesions on psychostimulant-induced locomotor sensitization.
