Wide-genome analysis of hepatocytes isolated from male and female rats treated with glucocorticoid.


ABSTRACT: Glucocorticoids are widely used therapeutically to suppress inflammatory/immune responses and most of their effects are produced either by altering transcription of specific genes directly, or by altering the expression of transcription factors that subsequently alter the expression of downstream genes. Relevant data from previous studies indicate that the number of genes regulated by glucocorticoid receptor exceeds 4000 in cells and that 358 different genes are regulated in the liver of adrenalectomized males rats treated with a chronic infusion of methylprednisolone for up to 1 week . However, differences in gene expression between males and females in response to glucocorticoid treatment in isolated hepatocytes are not known. Livers were isolated from adult male and female Sprague-Dawley rats and digested with the collagenase perfusion method developed by Berry and Friend (J Cell Biol 43, 506-520;1969). After collagenase treatment, the liver was excised, minced in balanced salt solution, and centrifuged at 50 g for 3 min. Immediately after isolation, hepatocytes were resuspended in Williams E Medium containing penicillin (100 units/ml), streptomycin (100 M-NM-
