Biol Reprod 110(2):275-287. doi: 10.1093/biolre/ioad147 PMID: 37930247
Objective: To investigate the role of NKB-SAP (NK3-SAP) in the arcuate nucleus on the timing of puberty, the LH surge, and the response to the NK3R agonist senktide in female sheep.
Summary: This study explores how the ablation of NK3R-containing neurons in the arcuate nucleus affects puberty onset and reproductive hormone dynamics in female sheep. The findings demonstrate that NK3-SAP injections significantly delay puberty, reduce the amplitude of the LH surge, and alter the response to senktide, underscoring the critical role of NK3R-containing neurons in reproductive function.
Usage: Prepubertal ewes received 1 μL (0.7 μg) of NKB-SAP (NK3-SAP) [IT-63] or Blank-SAP (IT-21) injections aimed at the arcuate (ARC) nucleus to ablate neurons expressing NK3R.
