Expression data from mouse lungs exposed in-utero and/or as an adult to second-hand smoke (SHS)

ABSTRACT: Second-hand smoke (SHS) exposure during pregnancy has adverse effects on offspring. We used microarrays to characterize the gene expression changes caused by in-utero exposure and adult exposure to SHS in adult mouse lungs. Left lungs from Balb/c male mice were collected at 15 weeks of age for RNA extraction and hybridization on Affymetrix mouse 430 2.0 microarrays. Based on their smoke exposure status, there are 4 groups of mice, each exposed in-utero to filtered-air or SHS and as an adult to filtered-air or SHS. We extracted RNA from 4 animals from each group for microarray analysis (N = 16 samples).

In utero exposure to second-hand smoke aggravates adult responses to irritants: adult second-hand smoke.

In utero exposure to second-hand smoke (SHS) is associated with exacerbated asthmatic responses in children. We tested the hypothesis that in utero SHS will aggravate the lung responses of young adult mice re-exposed to SHS. We exposed Balb/c mice in utero to SHS (S) or filtered air (AIR; A), and re-exposed the male offspring daily from 11-15 weeks of age to either SHS (AS and SS) or AIR (AA and SA). After the adult exposures, we analyzed samples of bronchoalveolar lavage fluid (BALF), examined ...[more]

Expression data from mouse lungs, exposed in-utero to second-hand smoke (SHS) and challenged with ovalbumin (OVA) as adults.

Project description:SHS exposure during pregnancy has adverse effects on offspring. We used microarrays to characterize the gene expression changes caused by in-utero SHS exposure and adult (19-23 weeks) OVA challenge in 23-week mouse lungs. Left lungs from Balb/c male and female mice were collected at 23 weeks of age for RNA extraction and hybridization on Affymetrix mouse 430 2.0 microarrays. Based on the gender differences and in-utero exposure status, there are 4 groups of mice, females and males, exposed in-utero to filtered-air or SHS. All were exposure to OVA (19-23 weeks). We extracted RNA from 4 animals from each group for microarray analysis (total N = 16 samples).

Expression data from adult mouse testis exposed to cigarette smoke in utero

Project description:In the context of male reproductive health, epidemiological studies have observed reduced testis size and abnormal sperm counts and morphology in adult men exposed in utero, although these findings are not always repeated. The ambiguity of these reports is confounded by a lack of controlled animal studies investigating the effects of maternal cigarette smoke exposure on male offspring reproductive health. In this study we examined the effects of cigarette induced reproductive toxicity on male offspring exposed during the gestational and weaning period using our novel direct nasal exposure mouse model of cigarette smoke-induced chronic obstructive pulmonary disease and female subfertility. This was done too gain a better understanding of the adverse effects of gestational maternal smoking on male offspring fertility. C57BL/6 5 week-old female mice were exposed via the nose-only to cigarette smoke [twelve 3R4F reference cigarettes (University of Kentucky, USA) twice/day, five times per week, for 12-18 weeks]. Each exposure lasted 60 minutes. Control mice received room air. In total, 27 mice underwent cigarette smoke exposure. Eleven week-old female mice exposed to cigarette smoke for 6 weeks were separated into groups of three and housed with a single control stud male aged 7-8 weeks with proven fertility for a maximum of 12 weeks. Females were monitored every second day for post-coital plugs and pregnancy. Pregnant females were separated into single cages and litter sizes/pup weights recorded. Smoke exposure via dams continued throughout mating/pregnancy/lactation until weaning of pups at 21days post birth. The testis of exposed offspring were then collected for RNA extraction and hybridization on an Illumina Sentrix Mouse ref-8 v2 Beadchip

Diet-Induced Obesity Exacerbates Inflammatory and Oxidative Stress Responses in Mice Exposed to Cigarette Smoke

Project description: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 lung tissue. Groups (N=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.

In Utero Cigarette Smoke Affects Allergic Airway Disease But Does Not Alter the Lung Methylome

Project description:Introduction: Prenatal and postnatal cigarette smoke exposure enhances the risk of developing asthma. Despite this as well as other smoking related risks, 11% of women still smoke during pregnancy. We hypothesized that cigarette smoke exposure during prenatal development generates long lasting differential methylation altering transcriptional activity that correlates with disease. Methods: In a house dust mite (HDM) model of allergic airway disease, we measured airway hyperresponsiveness (AHR) and airway inflammation between mice exposed prenatally to cigarette smoke (CS) or filtered air (FA). DNA methylation and gene expression were then measured in lung tissue. Results: We demonstrate that HDM-treated CS mice develop a more severe allergic airway disease compared to HDM-treated FA mice including increased AHR and airway inflammation. While DNA methylation changes between the two HDM-treated groups failed to reach genome-wide significance, 99 DMRs had an uncorrected p-value < 0.001. 6 of these 99 DMRs were selected for validation, based on the immune function of adjacent genes, and only 2 of the 6 DMRs confirmed the bisulfite sequencing data. Additionally, genes near these 6 DMRs (Lif, Il27ra, Tle4, Ptk7, Nfatc2, and Runx3) are differentially expressed between HDM-treated CS mice and HDM-treated FA mice. Conclusions: Our findings confirm that prenatal exposure to cigarette smoke is sufficient to modify allergic airway disease, however, it is unlikely that specific methylation changes account for the exposure-response relationship. These findings highlight the important role in utero cigarette smoke exposure plays in the development of allergic airway disease. Lung DNA methylation profiles of mice exposed in utero to cigarette smoke (CS) then treated with house dust mite (HDM, n = 8) or saline (n = 6), or exposed in utero to filtered air (FA) then treated with HDM (n = 9) or saline (n = 6)

Impaired Transcriptional Response of the Murine Heart To Cigarette Smoke in the Setting of High Fat Diet and Obesity

Project description: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.
