The baboon oviduct: characteristics of an oestradiol-dependent oviduct-specific glycoprotein.
The baboon oviductal epithelium differentiates into a tall columnar epithelium consisting of ciliated and secretory cells during the follicular phase of the menstrual cycle in response to rising oestradiol levels. The apical tips of these secretory cells are filled with membrane-bound secretory granules. During the luteal phase when progesterone levels are elevated, the epithelium regresses and...

this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
15 صفحه اولCloning and characterization of the human oviduct-specific glycoprotein (HuOGP) gene promoter.
Oviduct-specific glycoprotein (OGP) is a high molecular weight glycoprotein belonging to the chitinase protein family. OGPs are found to associate with the zona pellucida and plasma membrane of the oocyte and developing embryo. Recent studies have shown that OGP plays an important role in pre-fertilization reproductive events (i.e. sperm capacitation, sperm-zona binding and zona penetration). T...
متن کاملPurification, sequence characterization and effect of goat oviduct-specific glycoprotein on in vitro embryo development.
Oviduct-specific glycoprotein (oviductin) plays an important role during fertilization and early embryonic development. The oviductin cDNA was successfully cloned and sequenced in goat, which possessed an open reading frame of 1620 nucleotides representing 539 amino acids. Predicted amino acid sequence showed very high identity with sheep (97%) followed by cow (94%), porcine (77%), hamster (69%...
متن کاملInteraction of oestrogen and progesterone receptors with specific subfractions of laying-hen oviduct chromatin.
Salt (NaCl)-extracted nuclear oestrogen receptor from hen oviduct was incubated with salt-depleted oviduct chromatin and dialysed to low salt. The oestrogen receptor (re)associated with chromatin to form a 13-14S-sedimenting fraction, as found in 'native' chromatin, and saturation of this interaction was obtained for very low receptor concentrations (approx. 0.04 nM). Similarly, purified proges...
