Growth hormone secretagogue actions on the pituitary gland: Multiple receptors for multiple ligands?

, 2000
1.Growth hormone (Gli) secretion is thought to occur under the reciprocal regulation of two hypothalamic hormones, namely GH-releasing hormone (GHRH) and somatostatin (SRIF), through their engagement with specific cell-surface receptors on the anterior ...

Toxic Effects of Bisphenol A and Its Analogs on Ovarian Structure and Function: A Narrative Review of Ovary‐Focused Studies

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) is a widely used industrial chemical found in polycarbonate plastics and epoxy resins and is recognized for its endocrine‐disrupting properties. Human exposure is common due to its presence in food packaging and everyday products. As BPA use has been restricted, structurally similar compounds such as BPS, BPB, BPAF, and BADGE

Cloning and charaterisation of the Thyrotrophin-releasing hormone receptor and Gonadotrophin-relasing hormone receptor from chicken pituitary gland [PDF]

, 1998
The hypothalamic hormones, thyrotrophin-releasing hormone (TRH) and gonadotrophin-releasing hormone (GnRH), play pivotal roles in the growth and sexual maturation of chickens. In chickens, TRH regulates the release and synthesis of thyrotrophin (TSH) and

Potential Neuroendocrine Disruption by Benzodiazepines and Its Impact on Male Fertility

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neuroactive substances have emerged as potent endocrine disruptors affecting male reproductive health through central and peripheral mechanisms. Among these, benzodiazepines, which are widely used for the management of anxiety, insomnia, epilepsy, and neuromuscular disorders, are known as GABA A (gamma‐aminobutyric acid type A) receptor ...

Distinct sex differences in the production of steroids and neuropeptides in the adult zebrafish brain–pituitary–gonadal axis

FACETS
Zebrafish are valuable models for studies of human disease, environmental toxicology, and reproductive biology. However, sex differences in hormone production are rarely examined, despite gene mutation studies showing differential effects in females and ...

Offspring Global DNA Methylation is not Affected by Parental Developmental Stress Experience in a Passerine Species

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Rapid phenotypic change may be mediated by intergenerational transmission of early developmental experiences. In birds, exposure to glucocorticoids during early development can alter global DNA methylation and gene expression. However, DNA methylation is labile, and it is currently unclear whether the impacts of stress suffered during juvenile

The Enteric Nervous System: An Integrative Hub From Development to Systemic Physiology

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Unlike a static hardwired circuit, the ENS continuously remodels its transcriptional programs and synaptic connectivity in response to three ecological forces: microbial metabolites, immune cell signals and enteroendocrine cues. ABSTRACT The enteric nervous system (ENS) constitutes the largest and most functionally autonomous subdivision of the ...
