Gestational food-restriction but not nicotine exposure regulates gene expression in the striatum of adolescent rats

ABSTRACT: We used microarrays to determine the effect of prenatal nicotine exposure on gene expression profiles in the striatum of adolescent rats. We found a number of immediate early genes to be differentially expressed due to food-restriction. We compared control (n=8), nicotine exposed (n=7) and a group of animals matched to the food intake of nicotine exposed animals (n=10) to identify gene expression changes associated with prenatal nicotine exposure

The prenatal nicotine exposure leads to epigenetic alterations in nervous system signaling genes in the rat [RNA-seq]

Project description:Background. Prenatal exposure to nicotine has been documented to impose numerous deleterious effects on fetal development. However, the epigenetic changes promoted by nicotine exposure on germ cell are still not well understood. Objectives. In this study, we focused on elucidating the impact of prenatal nicotine exposure on regulatory epigenetic mechanisms important for the germ cells development. Objectives.

Effect of prenatal exposure to nicotine on kidney structure and gene expression in rats

Project description:Here, we investigated whether prenatal exposure to nicotine alters kidney glomerular mass and genome-wide gene expression profiles in two genetically distant strains of rats, namely spontaneously hypertensive rats (SHR) and Brown Norway (BN) rats. Nicotine or saline were administered to BN and SHR dams via osmotic pumps throughout gestation. Kidneys from 9-week-old male offspring were studied. Equal amounts of RNA from individual animals were pooled within each of the four experimental groups SHR (nicotine: n=13; saline: n=12) and BN (nicotine: n=12; saline: n=12) and hybridized with the Rat RAE-230a GeneChip (Affymetrix).

Effect of Nicotine on neural tube development

Project description:Neural tube defects (NTD) occur in 3000 births per year in the US. Several risk factors have been proposed for NTDs including both first hand and passive smoking during the periconceptual period. Previously we reported an increased frequency of cervical region NTD in a chicken model of prenatal nicotine exposure (Bohn, Humphrey et al. 2014; Humprey, Bohn et al. 2014). Here, we will reveal the mechanisms of the insult. The specific aims include: 1) Evaluation of the gene expression changes in the chicken model of nicotine exposure that we developed previosly. Such genome-wide analysis of the expression allows to collect very detailed data regarding the drug impact. To our knowlidge, comparable analysis of nicotine induced changes in gene expression during development of any species has never been conducted. 2) Evaluation of nicotine induced alterations in tadpoles (Xenopus tropica). The frogs will be treated in a manner similar to chicken (the same drug doses and a matched time of sacrifice) and analyzed both histologically and for gene expression. Incorporation of a different group of vertebrates in this study is essential for dissecting the evolutionary conserved role this pathway of interest in development which is another strong aspect of this proposal. We believe, that our comparative approach will allow more effective extrapolation of data from animal models to humans and better understanding of the evolutionary process. Nicotine is one of the most common developmental insults in humans. The consequences of this exposure are well-documented. However, the affected pathways are unknown. The identification of the mechanisms of nicotine induced alterations proposed here is vital for development of better treatment strategies.

Effect of paraquat and nicotine on gene expression in a Drosophila melanogaster Parkinson's disease model

Project description:Cigarette smoking is associated with reduced risk of developing Parkinson’s disease (PD). To identify genes that interact with nicotine/smoking, we performed hypothesis-free genome-wide experiments in a paraquat-induced Drosophila model and in a case-control study of PD. We demonstrated that nicotine extends life-span in paraquat-treated Drosophila (P=4E-30). Brain tissue from flies treated with combinations of paraquat and nicotine revealed elevated expression of CG14691 with paraquat which was restored with nicotine co-treatment (P(interaction)=2E-11, P(FDR-adjusted)=4E-7). Independently, variants in the 5’ region of SV2C, a human ortholog of CG14691, gave the strongest signal for interaction with smoking (P(interaction)=9E-8). The effect of smoking on PD risk varied six-fold by SV2C genotype (P(heterogeneity)=4E-10). Moreover, SV2C variants identified here were associated with SVC2 gene-expression in the HapMap data. Present results suggest synaptic vesicle protein SV2C plays a role in PD pathogenesis, and that the SV2C genotype may be useful for clinical trials of nicotine for treating PD. Drosophila female heads were dissected after exposure to plain food, food with paraquat, food with nicotine, or food with both paraquat and nicotine, and genome-wide expression was quantified using Affymetrix microarrays. 20 heads were pooled per replicate, with each treatment in triplicate, and all flies were dissected at the same timepoint, after 10 days of pretreatment (with 0.1 mg/ml nicotine or no nicotine, depending on treatment group), and then a further 6 days of treatment with either 5 mM paraquat or no paraquat, continuing on the pretreatment dose of nicotine. One biological replicate in the paraquat-only group showed RNA degradation and was not included in the normalization or subsequent analyses.

Paternal nicotine exposure promotes hepatic fibrosis in offspring

Project description:Paternal nicotine exposure can alter phenotypes in future generations. To explore whether paternal nicotine exposure affects the hepatic repair to chronic injury which would lead to hepatic fibrosis in offspring, we establish a paternal effect model based on nicotine exposure in mice.

Transcription profiling by array of brain from zebrafish treated with ethanol or nicotine suggests conservation of neuro-adaptation pathways

Project description:Effect of ethanol or nicotine exposure on gene expression compared to control. Duplicate arrays from ethanol or nicotine treated animals compared with triplicate arrays from paired control animals. In total 4 treatment arrays (2 ethanol, 2 nicotine) and 3 control arrays (from control animals treated in parallel with ethanol-treated fish and nicotine-treated fish.)
