Estrogen promotes gonadotropin-releasing hormone expression by regulating tachykinin 3 and prodynorphin systems in chicken

Poultry Science
: The “KNDy neurons” located in the hypothalamic arcuate nucleus (ARC) of mammals are known to co-express kisspeptin, neurokinin B (NKB), and dynorphin (DYN), and have been identified as key mediators of the feedback regulation of steroid hormones on ...

Neuroendocrine mechanisms leading to novel control techniques of reproduction in livestock: Regulation of the GnRH pulse generator activity

The Journal of Reproduction and Development
Pulsatile secretion of gonadotropin-releasing hormone (GnRH) is essential for normal reproductive function in mammals. GnRH pulses from the hypothalamus drive pulsatile gonadotropin release from the anterior pituitary, thereby

Potential role of kisspeptin in the estradiol-induced modulation of inhibin subunit gene expression: Insights from in vivo rat models and hypothalamic cell models

Endocrine Journal
The hypothalamic-pituitary-gonadal (HPG) axis is primarily regulated by kisspeptin neurons. In addition, activin and inhibin within the central nervous system might contribute to the regulation of the HPG axis because they are expressed near kisspeptin ...

Environmental heat exposure and female pubertal timing: biological plausibility, emerging evidence and research priorities

Global Pediatrics
Over the past century, female pubertal timing has progressively advanced and this trend cannot be fully explained by genetic factors, childhood obesity, endocrine-disrupting chemicals, air pollution or other established risk factors alone, thereby ...

Molecular Mechanisms of Dysregulated LH and FSH Secretion in Human Reproductive Failure

Biomedicines
Several reproductive issues in both men and women are caused by changes in the pulsatile secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

Arcuate ER alpha-mediated estrogen signaling pathways and regulation of KNDy-associated gene expression in female mice

, 2016
Central signaling of 17β-estradiol (E2) in the arcuate nucleus (ARC) is important in many homeostatic functions including reproduction, energy balance, and thermoregulation, among others.

Regulation of NKB pathways and their roles in the control of Kiss1 neurons in the arcuate nucleus of the male mouse.

, 2011
Kisspeptin (Kiss1) and neurokinin B (NKB) (encoded by the Kiss1 and Tac2 genes, respectively) are indispensable for reproduction. In the female of many species, Kiss1 neurons in the arcuate nucleus (ARC) coexpress dynorphin A and NKB.
