Moreover, the most of the PNX-expressing neurons in the hypothalamus also co-express nesfatin-1. These outcomes may suggest that there is an interaction between PNX and nesfatin-1, at least in terms of neuroendocrine-mediated regulations. Hence, the study was planned to find out the effects of centrally delivered PNX and nesfatin-1 on male sex hormones or to show the interactive association of intracerebroventricularly (ICV) injected PNX+nesfatin-1 combination on the release of male hormones. PNX and nesfatin-1, single or together, were delivered ICV to different male Wistar Albino rat groups. Both PNX and nesfatin-1 induced a significant enhancement in plasma FSH, LH and testosterone without inducing any alteration in plasma GnRH in the rats. The central combinatorial treatment of both the neuropeptides produced a more potent rise in male plasma hormone levels than treating with single neuropeptide. In summary, our preliminary data show that centrally delivered PNX and nesfatin-1 can affect plasma male hormone levels. Moreover, that the combinatorial treatment with both the neuropeptides in male rats leading to a more potent effect on the plasma male hormone levels might suggest that both these neuropeptides act synergistically in terms of regulation of male HPGA.eninfo:eu-repo/semantics/openAccessHypothalamic-pituitary-gonadal axisIntracerebroventricularMale sex hormonesNesfatin-1PhoenixinLuteinizing-hormoneGonadotropin-secretionFood-intakePeptideBrainNucb2/nesfatin-1TestosteroneNeuropeptıdeExpressıonPubertyAnimalsGonadotropin-Releasing HormoneGonadotropinsPituitaryHypothalamic HormonesMaleNucleobindinsPeptide hormonesRatsWistarTestosteroneArticle0004919294000012-s2.0-85074360824511131637758https://doi.org/10.1111/and.13410AndrologyNesfatin-1; Calcium-Binding Protein; Hypothalamus
