The results for gpr54-1 mRNA signals (A, D, G) and gpr54-2 mRNA signals (C, F, I) show that the gpr54-1- and gpr54-2-expressing neurons are localized in the POA surrounding the GnRH1 neurons (A–C), but not in the midbrain tegmentum surrounding the GnRH2 ...

Expressions of Kisspeptin System and Ki‐67 in the Reproductive Tissues of Cyclic Bitches
ABSTRACT Kisspeptin is a peptide that plays a pivotal role in the central regulation of gonadotropins. It is regarded as a key regulator of reproductive processes, including follicular and luteal development and endometrial remodelling. The objective of this study was to investigate the expression of KISS1, its receptor KISS1R and the proliferation ...

We identified 45% HFD as the optimal formulation to establish a juvenile rat model of obesity‐related precocious puberty. It elicits robust phenotypic (early vaginal opening, obesity), histological (advanced ovarian development), and endocrine (elevated HPG axis hormones) alterations, with leptin‐mediated GnRH secretion as a core mechanistic driver ...

Kisspeptin regulation of genes involved in cell invasion and angiogenesis in first trimester human trophoblast cells. [PDF]
The precise regulation of extravillous trophoblast invasion of the uterine wall is a key process in successful pregnancies. Kisspeptin (KP) has been shown to inhibit cancer cell metastasis and placental trophoblast cell migration.

KISS1 and Its G Protein-Coupled Receptor (GPR54) in Cancer Progression and Metastasis [PDF]
Activation of G-protein coupled receptor 54 (GPR54) signaling generated by kisspeptins (endogenous GPR54 ligands encoded by KISS1 gene) has been known to regulate puberty and to suppress cancer metastasis. However, an endogenous GPR54 signaling in cancer

GPR54 (Kiss1R) immunostaining in the Placenta.
Fig. 2 (a–c) demonstrate GPR54 immunohistochemistry with individual villous cytotrophoblast cell staining for GPR 54 (red) in the placental villus (pv) (Fig. 2a). Fig. 2b shows GPR54 (red) immunostaining of villous cytotrophoblasts (vCT), cytotrophoblast

The study identified a novel SEMA3A exons 6–9 deletion variant in Kallmann syndrome that impairs GnRH neuronal migration and alters cell migration, gonad development, and synaptic pathways. The study expands mutation spectrum and offers mechanistic insights for clinical diagnosis of Kallmann syndrome.
