Abstract
This study was conducted to determine the
correlation between vitamin A restriction and serum metabolites as well as
global proteins expression. Forty-eight animals were randomly divided into three groups and given different vitamin A
supplementation: High
(4.8 IU/g feed), Medium
(2.43 IU/g feed) and Low
(1.14 IU/g feed). Blood was
collected individually via the external jugular veins. Results showed that the
concentrations of Ca, total cholesterol,cortisol and cortisone, and the activity of 11beta-hydroxysteroid dehydrogenase (11-HSD)
type 2 varied among the groups. An up-regulated (hibernation
protein 25) and four down-regulated proteins (gelsolin a,alpha-1-microglobulin/bikunin
precursor, transthyretin, and complement factor B) were identified in a proteomics study.Thesedata demonstrated thatvitamin A deficiency had considerable effects on the serum levels of
several metabolites and global proteins expression and these
metabolites and proteins may be used as physiological markers in thestudy of
adipogenic differentiation preventionby vitamin A.
