Dataset: Diet-Induced Obesity Reprograms the Inflammatory Response of the Murine Lung to Inhaled Endotoxin

To identify key biological pathways that define susceptibility factors for pulmonary infection during obesity, diet-induced obese (DIO) and regular weight (RW) C57BL/6 mice were exposed to 0.5 µg/L inhaled lipopolysaccharide (LPS) for 1 hr/d for 4 days over a period of 2 weeks. Transcriptional responses were measured by global microarray analysis of lung tissue. Groups (N=8 biological replicates) of regular weight (RW) and diet-induced obese (DIO) C57BL/6 mice (15-weeks old at start of exposures) were exposed to either filtered air (sham controls, SC) or 0.5 µg/L LPS by nose-only inhalation exposure for 1 hr/day for 4 days over a 10-day period with necropsies occurring on the day following the last exposure (Day 11).
