Purification and immunochemistry of a soluble matrix protein of the chicken eggshell (ovocleidin 17)
Publikováno v:
Calcified Tissue International. 56:578-583
The protein components of biomineralized structures (matrix proteins) are believed to modulate crystal nucleation and growth, and thereby influence the shape and strength of the final structure. The chicken eggshell contains a complex array of distin

1. Withdrawal of cholecalciferol (D3) supplement from a layers diet drastically reduced blood 25-hydroxycholecalciferol (25-OH-D3), 1 alpha,25-dihydroxycholecalciferol (calcitriol) and egg specific gravity (SG) within two weeks, followed by a decreas

1. The protein components of the domestic fowl's eggshell are believed to influence appreciably the mechanical properties of the shell and/or its biomineralisation. The purpose of this study was to compare the protein species composing the eggshell m

1. The effect of replacing dietary cholecalciferol (D3) by 1 alpha,25-dihydroxycholecalciferol (1,25-(OH)2D3) on egg shell quality and egg production was tested on 32-week-old White Leghorn laying hens over 9 weeks. 2. Hens fed on a diet supplemented

Estrone sulfate, estrone, and estradiol-17β have been assayed in blood plasma taken from the mammary vein of five pregnant cows before and after parturition. While there were considerable individual variations, the mean plasma levels of estrone sulf

When equimoles of 4-14C-11β-hydroxyprogesterone and 1,2-3H-11-deoxycorticosterone are incubated with rat adrenal quarters for 3 h, they are incorporated to the same extent into corticosterone or aldosterone. The addition of an NADPH-generating syste

Levels of plasma estrogens and total calcium were studied during the second laying year in two high performance strains (1 and 4) of White Leghorns approximately 6 to 8 hr after oviposition. Each strain had been divided into two groups, those that ha

Plasma samples from nine White Leghorn hens collected over six different intervals during the laying cycle contained high concentrations of estradiol-17β-3-sulfate with an overall mean of 1.24 pmol/ml (464 pg/ml) versus .36 pmol/ml (98 pg/ml) for es

Supplemental vitamin D3 (D3) was removed from the diet given to an experimental group of White Leghorn hens, at 227 days of age, while a control group continued to receive a supplemental diet. By 14 days after D3 withdrawal, egg weight, egg specific

Vitamin D-deficient chicken embryos were obtained by feeding laying hens diets in which 3-7 micrograms calcitriol replaced the vitamin D3 supplement. A large proportion of the D-deficient embryos failed to complete the prehatching positional changes
