SLC2A1 and hypothyroidism: Although kisspeptin-10 treatment did not improve maternal glucose homeostasis or prevent feto-placental growth restriction, it attenuated maternal hypothyroidism-induced placental Glut1 dysregulation, upregulated the IGF1/IGF1R axis, and restored placental AKT/mTOR expression.<h4>Conclusion</h4>These findings suggest that kisspeptin-10 treatment in hypothyroid pregnant rats improves placental mTOR signaling and glucose metabolism mediators, highlighting novel pathways through which kisspeptin may modulate placental physiology.
