Crossover of the hypothalamic pituitary-adrenal/interrenal (HPA), -thyroid (HPT), and -gonadal (HPG) axes in testicular development

open access: yesFrontiers in Endocrinology, 2014
Besides the well-known function of thyroid hormones (THs) for regulating metabolism, it has recently been discovered that THs are also involved in testicular development in mammalian and non-mammalian species.

Involvement of the hypothalamic-pituitary-thyroid axis and its interaction with the hypothalamic-pituitary-adrenal axis in the ontogeny of avian thermoregulation: a review [PDF]

open access: yes, 2008
The emergence of thermoregulation in avian species is a complex matter in which neural as well as hormonal processes are involved. In a previous paper, the neural aspects of primary avian thermoregulation were discussed.

Hypothalamic-Pituitary-Gonadal Endocrine System in the Hagfish

open access: yesFrontiers 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).

Developmental and functional effects of steroid hormones on the neuroendocrine axis and spinal cord [PDF]

open access: yes, 2016
This review highlights the principal effects of steroid hormones at central and peripheral levels in the neuroendocrine axis. The data discussed highlight the principal role of oestrogens and testosterone in hormonal programming in relation to sexual ...

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

open access: yesСибирский 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 ...

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

open access: yesExpert 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

Effect of Soyabean Isoflavones Exposure on Onset of Puberty, Serum Hormone Concentration and Gene Expression in Hypothalamus, Pituitary Gland and Ovary of Female Bama Miniature Pigs [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2015
This study was to investigate the effect of soyabean isoflavones (SIF) on onset of puberty, serum hormone concentration, and gene expression in hypothalamus, pituitary and ovary of female Bama miniature pigs.

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

open access: yesEndocrinology, 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

PACAP induces FSHβ gene expression via EPAC. [PDF]

open access: yes, 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.

Glycosylation in the thyroid gland : vital aspects of glycoprotein function in thyrocyte physiology and thyroid disorders [PDF]

open access: yes, 2018
The key proteins responsible for hormone synthesis in the thyroid are glycosylated. Oligosaccharides strongly affect the function of glycosylated proteins.
