Differential Control of Immunoreactive α-Inhibin and Progesterone Production by Marmoset Luteal Cells in Vitro: Evidence for a Paracrine Action of α-Inhibin on Basal and Gonadotropin-Stimulated Progesterone Production1

Autor: G. E. Webley, P. G. Knight, P. L. Marsden

Publikováno v: Biology of Reproduction. 50:1394-1402

There is an increase in plasma concentrations of immunoreactive (ir) inhibin unaccompanied by a rise in plasma progesterone during early pregnancy in the marmoset monkey. We investigated the potential involvement of hCG and prostaglandin E 2 (PGE2 )

Changes in plasma concentrations of immunoreactive inhibin, progesterone, and bioactive gonadotrophin during pregnancy in the marmoset monkey

Autor: P. G. Knight, P. L. Marsden, G. E. Webley

Publikováno v: American Journal of Primatology. 32:187-195

This study describes the peripheral concentrations of immunoreactive (ir) inhibin, progesterone, and bioactive gonadotrophin during pregnancy in the marmoset monkey, a New World primate. Blood samples were taken every two weeks from six animals from

Roles of cyclic AMP and inositol phosphates in the luteolytic action of cloprostenol, a prostaglandin F2 analogue, in marmoset monkeys (Callithrix jacchus)

Autor: A. E. Michael, G. E. Webley

Publikováno v: Reproduction. 97:425-431

The luteolytic response to a prostaglandin F2 alpha analogue, cloprostenol, was investigated in vivo and in vitro at defined stages of the luteal phase. In vivo administration of cloprostenol to female marmoset monkeys on day 3 after ovulation had no

Evidence that Most of the Radioimmunoassayable Inhibin Secreted by the Corpus Luteum of the Common Marmoset Monkey is of a Non-Dimeric Form1

Autor: Shanthi Muttukrishna, N Groome, G E Webley, Philip G. Knight

Publikováno v: Biology of Reproduction. 47:554-560

Although recent data for several species of prinsate, including human and marmoset, indicate that the corpus luteum secretes high levels of radioimmunoassayable inhibin, the nature of the immunoreactive (if) inhibin detected has not been established.

Preincubation of human granulosa cells with gonadotrophin prevents the cloprostenol-induced inhibition of progesterone production

Autor: M. C. Richardson, A. Given, G. E. Webley, J. Harper

Publikováno v: Human Reproduction. 6:779-782

Human granulosa cells, from women undergoing ovum collection for in-vitro fertilization (IVF), will luteinize in vitro and provide a model for investigating the antigonadotrophic action of a prostaglandin F2 alpha (PGF2 alpha) analogue, cloprostenol,

Effect of constant-release melatonin implants on the onset of oestrous activity and on reproductive performance in the ewe

Autor: C. M. Argo, L. A. Durotoye, G. E. Webley, M. E. McNeil, R.R. Rajkumar, N. B. Graham, R. Nowak, R. G. Rodway

Publikováno v: Animal Science. 52:489-497

Various types of constant-release melatonin implants were designed and administered to adult ewes during seasonal anoestrus. Implants were given between May and July in a series of four experiments. Treatment of ewes with melatonin implants resulted

Increased concentrations of immunoreactive inhibin during conception cycles in the marmoset monkey: suppression with an LHRH antagonist and cloprostenol

Autor: A. Given, G. E. Webley, J. K. Hodges, P. G. Knight

Publikováno v: Journal of Endocrinology. 128:465-473

Peripheral concentrations of immunoreactive (ir) inhibin have been measured during the ovarian cycle and early pregnancy in the marmoset monkey. Blood samples were taken (three per week) during conception (n = 6) and non-conception (n = 5) cycles. Ir

Size distribution of luteal cells from pregnant and non-pregnant marmoset monkeys and a comparison of the morphology of marmoset luteal cells with those from the human corpus luteum

Publikováno v: Reproduction. 90:427-437

The size distribution of marmoset luteal cells was determined on Days 6, 14 and 20 after ovulation in non-pregnant cycles and in early pregnancy. Image analysis was used to estimate the cell diameter of dispersed cells prepared from the marmoset corp
