RNA-seq study on time of day specific Glucocorticoid action in mouse liver and lung tissues


ABSTRACT: Glucocorticoids are critical regulators of energy metabolism and immunity and major drug targets in inflammatory disease. It is also known that the circadian clock regulates both metabolism and immunity. This experiment is part of wider study to understand the coupling between circadian clock components and Glucocorticoid receptor in multiple mouse tissues. Here, RNA-seq analysis was performed in vehicle and dexamethasone (a synthetic Glucocorticoid) treated WT mouse liver and lung tissues at two circadian times, to understand time of the day variation in Glucocorticoid regulated genes. Mice were treated at ZT6 (6 hours after lights on, 1:30pm) or at ZT18 (6 hours after lights off, 1:30am) with dexamethasone (1 mg/kg intraperitoneal) or vehicle (methylcyclodextrin 1mg/kg intraperitoneal) for 2 hours before sacrifice by cervical dislocation. Lung and liver tissue were lysed and total RNA prepared using SV Total RNA Isolation System (Promega). Quality and integrity of total RNA samples were assessed by 2100 Bioanalyzer or a 2200 TapeStation (Agilent Technologies) according to the manufacturer’s instructions. RNA sequencing (RNA-seq) libraries were generated using the TruSeq® Stranded mRNA assay (Illumina, Inc.) according to the manufacturer’s protocol. Then paired-end sequenced (101 + 101 cycles, plus indices) on an Illumina HiSeq2500 instrument.
