Impaired Transcriptional Response of the Murine Heart To Cigarette Smoke in the Setting of High Fat Diet and Obesity
Ontology highlight
ABSTRACT: To identify biosignatures that describe these lifestyle susceptibility factors, we performed parallel exposures of regular weight (RW) C57BL/6 and diet-induced obese (DIO) C57BL/6 mice to cigarette smoke, either mainstream (MS) or sidestream (SS), mimicking both the smoker and environmental exposure through second-hand smoke, respectively. Transcriptional responses were measured by global microarray analysis of heart tissue. Groups (N=6-8 biological replicates) of RW and DIO C57BL/6 mice (15-weeks old at start of exposures) were exposed to either filtered air (sham controls, SC), mainstream (MS) or sidestream (SS) cigarette smoke by nose-only inhalation exposure for 5 hr/day for a total of eight exposures over two weeks as follows: 5 consecutive days of exposure, followed by 2 days with no exposure, then three days of exposure, with necropsies occurring the day following the last exposure.
