Evidence that the LH surge in ewes involves both neurokinin B–dependent and –independent actions of kisspeptin.

Goodman RL, He W, Lopez JA, Bedenbaugh MN, McCosh RB, Bowdridge EC, Coolen LM, Lehman MN, Hileman SM (2019) Evidence that the LH surge in ewes involves both neurokinin B–dependent and –independent actions of kisspeptin. Endocrinology 160(12):2990-3000. doi: 10.1210/en.2019-00597

Objective: To determine if NKB is involved in the RCh of the ewe in the LH surge.

Summary: NKB signaling in the RCh increases kisspeptin levels critical for the full amplitude of the LH surge in the ewe, but kisspeptin release occurs independently of retrochiamatic area (RCh) input at the onset of the surge to initiate GnRH secretion.

Usage: Bilaterial injections in the RCh of either NK3-SAP or Blank-SAP.

Related Products: NKB-SAP (Cat. #IT-63), Blank-SAP (Cat. #IT-21)
