Experimental Protocol

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 μg/ml), 2 mM glutamine pH 7.4, and 10% fetal bovine serum and plated on collagen-coated 94 x 16 mm cell culture dishes and maintained for 24 hours in a 95% air–5% CO2, 37°C incubator. The medium was then changed to free serum Williams E Medium and maintained in culture for an additional 24 hours. Hepatocytes isolated from male and rats were treated with vehicle (0.01% ethanol) or dexamethasone (100 nm) for 6 hours. Total RNA from cells were extracted by using the RNeasy Midi Kit (Qiagen) according to the manufacturer’s instructions. All samples were treated with the RNase-free DNase set (Qiagen) and were kept at -80°C until labeling and hybridization.
