Arcuate nucleus‐specific progesterone receptor knockdown in female mice is sufficient to induce PCOS‐like hyperactivity in the reproductive axis

Journal of Neuroendocrinology, Volume 38, Issue 4, April 2026.
Abstract Mammalian reproductive function is dependent upon gonadal steroid hormone feedback within the hypothalamic–pituitary–gonadal (HPG) axis. In polycystic ovary syndrome (PCOS), impaired progesterone (P4) negative feedback leads to hyperactive pulsatile secretion of luteinising hormone (LH) and impaired reproductive function.

Effect of gonadectomy and hormone replacement on habenula‐induced dopamine inhibition in female and male rats

Journal of Neuroendocrinology, Volume 38, Issue 4, April 2026.
Abstract Sex differences have been noted in the prevalence and severity of several neurological and mental health disorders. Midbrain dopaminergic activity is implicated in the etiology of many of these disorders and therefore may also contribute to some commonly seen sex differences in presentation and treatment. The ability of the lateral habenula to

Atractylenolide III Alleviates the Lipid Metabolic Disorders in Ovariectomy‐Induced Estrogen‐Deficient Mice Through Repairing Intestinal Inflammation and Microenvironment

Journal of Obstetrics and Gynaecology Research, Volume 52, Issue 4, April 2026.
ABSTRACT Objective To investigate the mechanism by which Atractylenolide III (ATIII) alleviates ovariectomy‐induced, estrogen‐deficient lipid metabolism disorders through the repair of intestinal inflammation and the barrier microenvironment. Methods Female C57BL/six mice (8 weeks old) were randomly assigned to three groups: a blank control group (Con,

Expressions of Kisspeptin System and Ki‐67 in the Reproductive Tissues of Cyclic Bitches

Reproduction in Domestic Animals, Volume 61, Issue 4, April 2026.
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 ...

GABAB receptor‐mediated modulation of sensory neuron excitability: Roles of CaV2.2, G‐protein‐coupled inwardly rectifying potassium (GIRK) channels, and hyperpolarisation‐activated cyclic nucleotide‐gated (HCN) channels in human and mouse nociception

Experimental Physiology, Volume 111, Issue 4, Page 2026-2043, 1 April 2026.
Abstract Chronic visceral pain is a key symptom of irritable bowel syndrome. Modulation of voltage‐gated calcium and potassium channels by G protein‐coupled receptors plays a key role in dampening nociceptive transmission. Both baclofen and the analgesic peptide α‐conotoxin Vc1.1 activate GABAB receptors (GABABR), resulting in inhibition of CaV2.2 and ...
