Chromatin status and transcription factor binding to gonadotropin promoters in gonadotrope cell lines. [PDF]

, 2017
BackgroundProper expression of key reproductive hormones from gonadotrope cells of the pituitary is required for pubertal onset and reproduction. To further our understanding of the molecular events taking place during embryonic development, leading to ...

Hypothalamic-Pituitary-Gonadal Endocrine System in the Hagfish

Frontiers in Endocrinology, 2013
The hypothalamic-pituitary system is considered to be a seminal event that emerged prior to or during the differentiation of the ancestral agnathans (jawless vertebrates).

Changes in the content of hormones of hypothalamic-pituitary-thyroid axis in growth of single and multiple primary tumors in the presence of comorbidity

Сибирский онкологический журнал, 2022
Introduction. Thyroid dysfunction is known to be associated with higher risks of cancer development. The purpose of this study was to analyze levels of thyroid axis hormones in the hypothalamus, pituitary gland, thyroid, and blood serum of male and ...

Pesticide Exposure Alters Follicle-Stimulating Hormone Levels in Mexican Agricultural Workers [PDF]

, 2005
Organophosphorous pesticides (OPs) are suspected of altering reproductive function by reducing brain acetylcholinesterase activity and monoamine levels, thus impairing hypothalamic and/or pituitary endocrine functions and gonadal processes. Our objective

Growth hormone-releasing hormone and extra-pituitary tumorigenesis: therapeutic and diagnostic applications of growth hormone-releasing hormone antagonists

Expert Opinion on Investigational Drugs, 2003
Growth hormone-releasing hormone (GHRH) regulates growth hormone release from the pituitary. However, in addition to this neuroendocrine action, much evidence implies an additional role for GHRH in carcinogenesis in non-pituitary tissues. This role of GHRH in cancer development appears to be due to the operation of several mechanisms, which involve the

Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...

PACAP induces FSHβ gene expression via EPAC. [PDF]

, 2019
Gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), are heterodimers of a common α subunit and unique β subunits. Regulation of their levels, primarily by GnRH, is critical for reproductive function.

Cloning of the Chicken Pituitary Receptor for Growth Hormone-Releasing Hormone [PDF]

Endocrinology, 2006
Details of the regulation of GH in birds are unclear. In this report, a receptor was cloned from chicken pituitary cDNA with 61% amino acid sequence identity to the human pituitary GHRH receptor. Phylogenies inferred from sequence alignments support that this is the chicken counterpart of the GHRH receptor known in mammals. Northern blotting shows that
