Expression data from adult mouse ovaries exposed to cigarette smoke in vivo

ABSTRACT: Mammalian females are born with a finite number of non-renewing primordial follicles, the majority of which remain in a quiescent state for many years. Due to their non-renewing nature, these “resting” oocytes are particularly vulnerable to xenobiotic insult, resulting in premature ovarian senescence and the formation of dysfunctional oocytes. In this study we characterised the mechanisms behind cigarette smoke induced ovotoxicity, which is characterised by primordial follicle depletion. C57BL/6 5 week old female mice were exposed to cigarette smoke five times per week, for 12-18 weeks using a custom-designed and purpose-built nose-only, directed flow inhalation and smoke-exposure system. This was done in the hopes of gaining a better understanding of the mechanisms underpinning cigarette smoke induced ovotoxicity.

C57BL/6 5 week old female mice were exposed to cigarette smoke (twelve 3R4F reference cigarettes (University of Kentucky, USA) twice/day, 2.7 mg particulate matter) five times per week, for 12-18 weeks using a custom-designed and purpose-built nose-only, directed flow inhalation and smoke-exposure system. Their ovaries were then collected for RNA extraction and hybridization on an Illumina Sentrix Mouse ref-8 v2 Beadchip

Expression data from mouse neonatal ovarian DMBA and BaP culture experiments

Project description:Mammalian females are born with a finite number of non-renewing primordial follicles, the majority of which remain in a quiescent state for many years. Due to their non-renewing nature, these “resting” oocytes are particularly vulnerable to xenobiotic insult, resulting in premature ovarian senescence and the formation of dysfunctional oocytes. In this study we characterised the mechanisms of ovotoxicity for the ovotoxic agent 7,12-dimethylbenz-[a]anthracene (DMBA), which targets immature follicles. Neonatal mouse ovaries (PND3-4) were cultured in the presence of DMBA (50nM) or BaP (1uM) for 96 hours to observe their effects on the ovarian transcriptome. This was done in the hopes of gaining a better understanding of the mechanisms underpinning xenobiotic induced pre-antral ovotoxicity. Ovaries from day 3-4 Swiss neonatal mice were cultured in DMBA or BaP containing media for 96 hours. The ovaries were then collected for RNA extraction and hybridization on an Illumina Sentrix Mouse ref-8 v2 Beadchip

Expression data from mouse neonatal ovarian 3MC culture experiments

Due to their non-renewing nature, these resting oocytes are particularly vulnerable to xenobiotic insult, resulting in premature ovarian senescence and the formation of dysfunctional oocytes. In this study we characterised the mechanisms of ovotoxicity for the ovotoxic agent 3-methylcholanthrene (3MC), which targets immature follicles. Neonatal mouse ovaries (PND3-4) were cultured in the presence of 3MC (5 µM) for 96 hours to observe their effects on the ovarian transcriptome. This was done in the hopes of gaining a better understanding of the mechanisms underpinning xenobiotic induced pre-antral ovotoxicity. Ovaries from day 3-4 Swiss neonatal mice were cultured in 3MC containing media for 96 hours.

Expression data from mouse neonatal ovarian xenobiotic culture experiments

Project description:Mammalian females are born with a finite number of non-renewing primordial follicles, the majority of which remain in a quiescent state for many years. Due to their non-renewing nature, these “resting” oocytes are particularly vulnerable to xenobiotic insult, resulting in premature ovarian senescence and the formation of dysfunctional oocytes. In this study we characterised the mechanisms of ovotoxicity for three ovotoxic agents, 4-Vinylcyclohexene Diepoxide (VCD), Methoxychlor (MXC), and Menadione (MEN), all of which target immature follicles. Neonatal mouse ovaries (PND3-4) were cultured in the presence of 4-Vinylcyclohexene Diepoxide (50uM), Methoxychlor (50uM), and Menadione (5uM) for 96 hours to observe their effects on the ovarian transcriptome. This was done in the hopes of gaining a better understanding of the mechanisms underpinning xenobiotic induced pre-antral ovotoxicity.

Synergism of Iraqi Sand/Cigarette Smoke Co-Exposure in Rats

Project description:Synergism of Iraqi Sand/Cigarette Smoke Co-Exposure in Rats. 24 samples are used. A total of 102 rats will be separated into six exposure groups: each group consisting of 17 male CD Sprague-Dawley rats, 10 to 15 weeks old. The six exposure groups were each exposed via two routes: 1. nose-only inhalation exposures --- air or cigarette smoke; 2. whole-body inhalation exposures -- air or manufactured silica sand or Iraqi sand. The nose only exposures were conducted 3 hours per day, 5 days per week for 6 weeks. During the last two weeks of the nose - only exposures, whole-body exposure were also conducted 18-19 hours per day, 7 days per week.

Transcriptomics-based characterization of smoking and cessation effects in mouse muscle

Project description:COPD is a disorder characterized by the progressive development of airflow limitation that is not fully reversible. Cigarette smoke has been generally accepted as the most important of many risk factors for the development of COPD. We used microarray technology to perform comprehensive gene expression profiling of smoke exposure and cessation effects in mouse muscle tissue. Mice received nose-only exposure of 4% mainstream cigarette smoke or air (sham exposure) for 2 hours/day, 5 days/week for 2, 12 or 24 weeks. Mice undergoing smoke cessation received cigarette smoke exposure for 12 weeks, and then sham exposure for 12 weeks.

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
