Two novel sites of expression of NADPH cytochrome P450 reductase during murine embryogenesis: limb mesenchyme and developing olfactory neuroepithelia

Autor: D S, Keeney, M R, Waterman

Publikováno v: Developmental dynamics : an official publication of the American Association of Anatomists. 216(4-5)

While all cells in eukaryotic organisms probably express the gene encoding NADPH cytochrome P450 reductase, we identified two novel sites which have the highest local concentrations of P450 reductase transcripts during murine embryogenesis. One site

Preimplantation mouse blastocysts fail to express CYP genes required for estrogen biosynthesis

Autor: M, Strömstedt, D S, Keeney, M R, Waterman, B C, Paria, A J, Conley, S K, Dey

Publikováno v: Molecular reproduction and development. 43(4)

Implantation is initiated on day 4 in the mouse and on day 13 in the pig. The preimplantation pig blastocyst synthesizes steroid hormones, but whether preimplantation rodent embryos also have this ability has remained unresolved for the last two deca

In vivo model for chronic direct intratesticular drug administration

Autor: J P, Jarow, D S, Keeney, B, Robaire, L L, Ewing, B R, Zirkin

Publikováno v: Journal of andrology. 15(5)

The efficacy and toxicity of a new method for chronic direct intratesticular drug infusion were assessed in a rat model. To this end, luteinizing hormone (LH) or buffer was infused via miniosmotic pumps for 14 days directly into the parenchyma of Cop

Expression of testicular 3 beta-hydroxysteroid dehydrogenase/delta 5----4-isomerase: regulation by luteinizing hormone and forskolin in Leydig cells of adult rats

Autor: J I Mason, D S Keeney

Publikováno v: Endocrinology. 130(4)

LH is required to maintain the activity of 3 beta-hydroxysteriod dehydrogenase/delta 5----4-isomerase (3 beta HSD) in testicular Leydig cells. The objective of the present study was to determine whether LH and effectors such as forskolin, which act v

Effects of hypophysectomy and alterations in spermatogenic function on Leydig cell volume, number, and proliferation in adult rats

Autor: D S, Keeney, L L, Ewing

Publikováno v: Journal of andrology. 11(4)

The two major objectives of this study were to determine (i) whether the pituitary is required to maintain Leydig cell number per testis, and (ii) whether alterations in spermatogenic function in the absence of LH can affect Leydig cell volume, numbe
