Cre/lox generation of a novel whole-body Kiss1r KO mouse line recapitulates a hypogonadal, obese, and metabolically-impaired phenotype. [PDF]

open access: yes, 2019
Kisspeptin and its receptor, Kiss1r, act centrally to stimulate reproduction. Recent evidence indicates that kisspeptin is also important for body weight and metabolism, as whole-body Kiss1r KO mice, developed with gene trap technology, display obesity ...

The evolution and variety of RFamide-type neuropeptides: insights from deuterostomian invertebrates [PDF]

open access: yes, 2014
Five families of neuropeptides that have a C-terminal RFamide motif have been identified in vertebrates: (1) gonadotropin-inhibitory hormone (GnIH), (2) neuropeptide FF (NPFF), (3) pyroglutamylated RFamide peptide (QRFP), (4) prolactin-releasing peptide (

Evaluation of Potential Hormonal Activities of Ashwagandha (Withania somnifera)

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Ashwagandha is a widely used herb in traditional medicine systems, particularly Ayurveda. Despite its extensive tradition, growing concerns regarding its potential endocrinological effects have prompted scientific scrutiny. This review systematically evaluates the current preclinical, clinical, and case study evidence concerning AS's effects ...

Regulation and Possible Functions of Kisspeptin in the Medial Amygdala

open access: yesFrontiers in Endocrinology, 2017
Kisspeptin, encoded by the Kiss1 gene, is required for reproduction. Humans and mice lacking kisspeptin or its receptor, Kiss1r, have impairments in reproductive physiology and fertility.

Hypothalamic Kisspeptin Neurons and the Control of Homeostasis.

open access: yesEndocrinology, 2021
Hypothalamic kisspeptin (Kiss1) neurons provide indispensable excitatory transmission to GnRH neurons for the coordinated release of gonadotropins, estrous cyclicity and ovulation.

Potential roles for the kisspeptin/kisspeptin receptor system in implantation and placentation [PDF]

open access: yesHuman Reproduction Update, 2018
Initially identified as suppressors of metastasis in various types of cancer, kisspeptins are a family of neuropeptides that are key regulators of the mammalian reproductive axis. Accumulating evidence has shown that kisspeptin is able to control both the pulsatile and surge GnRH release, playing fundamental roles in female reproduction, which include ...

Advent of NK3R Antagonists for the Treatment of Menopausal Hot Flushes: A Narrative Review

open access: yesBJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT The menopause transition is marked by symptoms predominantly attributed to declining oestrogen levels. Approximately 80% of women experience associated symptoms, and 25% experience severe symptoms. The commonest are vasomotor symptoms (VMS), collectively referring to hot flushes and/or night sweats.

Optogenetic Activation of Arcuate Kisspeptin Neurons Generates a Luteinizing Hormone Surge-Like Secretion in an Estradiol-Dependent Manner

open access: yesFrontiers in Endocrinology, 2021
Traditionally, the anteroventral periventricular (AVPV) nucleus has been the brain area associated with luteinizing hormone (LH) surge secretion in rodents.
