Project description:Proteasome dysfunction is emerging as a novel pathomechanism for the development of chronic obstructive pulmonary disease (COPD), a major leading cause of death in the world. Cigarette smoke is one of the main risk factors for COPD and has been shown to impair proteasome function in vitro and in vivo. Importantly, proteasome activity is inhibited in COPD lungs while expression levels of proteasome subunits are not altered. In the present study, we dissected the molecular changes induced by cigarette smoke on proteasome function in lung epithelial cells and mouse lungs. We analyzed the integrity, composition, and the interactome of isolated 26S proteasome complexes from smoke-exposed cells and mouse lungs. Moreover, we applied native MS analysis to investigate whether reactive compounds of cigarette smoke directly modify and inhibit the 20S proteasome complex. Our data reveal that the 20S proteasome is slightly destabilized in the absence of any dominant modification of proteasomal proteins. 26S pulldown and stoichiometry analysis indicated that 26S proteasome complexes become instable in response to cigarette smoke exposure. Of note, the interactome of the 26S was clearly altered in smoke-exposed mouse lungs possibly reflecting an altered cellular composition in the lungs of the smoke-exposed mice. Taken together, our results suggest that cigarette smoke induces minor but detectable changes in the stability and interactome of 20S and 26S proteasome complexes which might contribute in a chronic setting to imbalanced proteostasis as observed in chronic lung diseases associated with cigarette smoking.

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 M-bM-^@M-^\restingM-bM-^@M-^] 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

Project description:To investigate the effect of cigarette smoke exposure on gene expression in airway epithelial cells of Canton S Drosophila melanogaster larvae, we isolated the airways of cigarette smoke exposed larvae and air controls. We then performed gene expression profiling analysis using data obtained from RNA-seq of smoke-exposed males, smoke-exposed females, air-control males and air-control females. For each group 4 biological replicates were prepared, representing 40-50 larval airways.

Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.

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.
