Expression and localization of growth hormone receptor in the oviduct of the laying hen (Gallus domesticus).
The purpose of the present study was to examine growth hormone receptor (GHR) gene expression by real-time PCR and demonstrate immunocytochemically the localization of GHR in four chicken oviductal parts, i.e. infundibulum, magnum, isthmus and shell gland. Experiments were carried out on Hy-Line laying hens decapitated 2 h after oviposition. GHR mRNA was expressed in all examined oviductal segm...
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...
متن کاملThe polyA regions of hen oviduct RNA.
Total RNA from hen oviduct has been hydrolysed with a mixture of T(1) and pancreatic ribonucleases. Poly(A) tracts in the digestion product have been isolated by binding to oligo(dT) cellulose. Of the four major ribonucleotides, the product has been shown to contain only adenylic acid. When separated on polyacrylamide gels, the poly(A) gave two peaks corresponding to average apparent lengths of...

diameter)in the gland and small(200 to 700 nm) in the epithelium. Epithelial cells containing secretory granules had a strong resemblance to those of the protodifferentiated gland cells appearing in the magnum of chicks pretreated with hormones. No avidin was observed in any epithelial goblet cells or ciliated cells. The findings paralleled those obtained by biotinylatedenzymes affinity cytoche...
متن کاملGlucocorticoid binding in the hen oviduct.
[(3)H]Triamcinolone acetonide (15nm) was incubated with cytosol (150000g fraction) prepared from oviducts of egg-laying hens. The extent of steroid binding, as determined by charcoal assays, was greatest between 2-4h at 4 degrees C. A similar time curve was obtained when cytosol preparations were first fractionated with (NH(4))(2)SO(4) before labelling. The addition of 10mm-Na(2)MoO(4) or 10mm-...
