  • Title: Influence of H-2-linked genes on glucocorticoid receptors in the fetal mouse palate.
    Author: Katsumata M, Baker MK, Goldman AS, Gasser DL.
    Journal: Immunogenetics; 1981; 13(4):319-25. PubMed ID: 7275225.
    Abstract:
    The binding of 3H-dexamethasone to cytosolic receptors in fetal jaws and in cytosols and nuclei of primary cell cultures of fetal palates was studied in various congenic strains of mice. The amount of specific binding was greater in palatal tissues from B10.A and B10.A(2R) mice than in B10 or B10.A(5R) preparations. These differences were not observed in the liver. Since the strains with higher levels of glucocorticoid receptor are known to be more susceptible to cortisone-induced cleft palate than the strains with low receptor levels, it is suggested that quantitative variation in receptor levels may be involved in determining H-2-linked differences in cleft-palate susceptibility. Whether or not this is the case, it appears that an H-2-linked gene affects the quantity of a cytosolic glucocorticoid-binding protein which translocates to the nucleus.
