Mouse study ties GABA transporter SLC32A1 to kisspeptin and GnRH at puberty

The wire

1. 01In Theriogenology, researchers report hypothalamic Slc32a1 mRNA falls at puberty; knockdown in mice advanced vaginal opening, raised Gnrh, Kiss-1, Gpr54, Igf-1 and Tac2, and lowered serum GABA.
2. 02Readers tracking kisspeptin and gonadorelin signaling get a mechanistic link between GABA-GABA(B) receptor tone and the kisspeptin-GnRH axis controlling puberty onset.
3. 03This is an animal and GT1-7 cell study of an endogenous pathway, not a peptide therapy test, and no human relevance is established.
