Gonadotrophins modulate hormone secretion and steady-state mRNA levels for activin receptors (type I, IIA, IIB) and inhibin co-receptor (betaglycan) in granulosa and theca cells from chicken prehierarchical and preovulatory follicles

Autor: R. T. Gladwell, Sara L Al-Musawi, Philip G. Knight, TM Lovell

Publikováno v: Reproduction. 133:1159-1168

Ovarian follicle development is regulated through endocrine and local mechanisms. Increasing evidence indicates roles for transforming growth factor β superfamily members, including inhibins and activins. We recently identified divergent expression

Differential expression of mRNAs encoding the putative inhibin co-receptor (betaglycan) and activin type-I and type-II receptors in preovulatory and prehierarchical follicles of the laying hen ovary

Autor: TM Lovell, R. T. Gladwell, Philip G. Knight

Publikováno v: Journal of Endocrinology. 188:241-249

Ovarian follicle development is primarily regulated by an interplay between the pituitary gonadotrophins, LH and FSH, and ovary-derived steroids. Increasing evidence implicates regulatory roles of transforming growth factor-β (TGFβ) superfamily mem

Variation in pituitary expression of mRNAs encoding the putative inhibin co-receptor (betaglycan) and type-I and type-II activin receptors during the chicken ovulatory cycle

Autor: Philip G. Knight, TM Lovell, R. T. Gladwell

Publikováno v: Journal of Endocrinology. 186:447-455

Secretion of LH and FSH from the anterior pituitary is regulated primarily by hypothalamic GnRH and ovarian steroid hormones. More recent evidence indicates regulatory roles for certain members of the transforming growth factor β (TGFβ) superfamily

Ovarian follicle development in the laying hen is accompanied by divergent changes in inhibin A, inhibin B, activin A and follistatin production in granulosa and theca layers

Autor: N. P. Groome, TM Lovell, Philip G. Knight, R. T. Gladwell

Publikováno v: Journal of Endocrinology. 177:45-55

To study the potential involvement of inhibin A (inhA), inhibin B (inhB), activin A (actA) and follistatin (FS) in the recruitment of follicles into the preovulatory hierarchy, growing follicles (ranging from 1 mm to the largest designated F1) and th

Differential effects of activin A on basal and gonadotrophin-induced secretion of inhibin A and progesterone by granulosa cells from preovulatory (F1-F3) chicken follicles

Autor: TM Lovell, Philip G. Knight, N. P. Groome, R. T. Gladwell

Publikováno v: Reproduction. :649-657

Previous work has shown that activin A is expressed selectively within the theca rather than the granulosa layer of preovulatory chicken follicles. In the present study, this finding was verified and the potential paracrine actions of activin A on ba

Modulatory effects of gonadotrophins and insulin-like growth factor on the secretion of inhibin A and progesterone by granulosa cells from chicken preovulatory (F1-F3) follicles

Autor: Philip G. Knight, N. P. Groome, R. T. Gladwell, TM Lovell

Publikováno v: Reproduction. :291-300

The aim of this study was to compare the actions and interactions of gonadotrophins (LH and FSH) and an analogue of insulin-like growth factor I (LR3-IGF-I) on the secretion of inhibin A, inhibin B and progesterone by cultured chicken granulosa cells

Agouti related protein (AgRP) is a recently discovered melanocortin receptors (MCR) antagonist implicated in the control of feeding behaviour. Expression of AgRP has been shown to be localized by in situ hybridization to the arcuate nucleus and media

Changes in Plasma Inhibin A Levels During Sexual Maturation in the Female Chicken and the Effects of Active Immunization Against Inhibin α-Subunit on Reproductive Hormone Profiles and Ovarian Function1

Autor: TM Lovell, R. T. Gladwell, Philip G. Knight, Nigel P. Groome

Publikováno v: Biology of Reproduction. 64:188-196

Inhibins and activins are firmly implicated in the control of pituitary FSH secretion and ovarian follicular development in mammals. As in mammals, inhibin A and activin A are expressed in the preovulatory follicles of birds, and a defined ovulation

Publikováno v: Endocrinology. 139:1164-1171

Accumulating evidence implicates inhibins and activins as endocrine and local regulators of follicular development in mammals, and it was recently confirmed that inhibin/activin alpha and betaA genes are also expressed in the avian ovary. To investig
