Project description:We hypothesized that gestational exposure to chlordecone can lead to alteration of murine ovary's epigenetic landscape. To test our hypothesis, we exposed mice to chlordecone during embryonic development and we analyzed F1 female progeny epigenetic mark H3K4me3 in ovaries. We performed ChIP using anti-H3K4me3 commercial antibody (Merck Millipore, 07-473). DNA-protein complexes were immunoprecipitated, eluted and then DNA were purified.

Project description:RNA seq project designed to understand the role of pesticide on transription of mRNA in the testis. We treated adult female mice with chlordecone with doses 0 (control), 100 Xg/kg/day and 1 mg/kg/day during gestation period E6- E15. Male born from Chlordecone- treated mice were crossed for a three generations. The testes from F3 generations were taken for mRNA extraction. For mRNA extraction we used columb. Three biological replicates used for each condition . We hypothesize that chlordecone cause changes in mRNA due to transgenerational effect of pesticides (Skinner et al, Science 2005). The changes in expression of certain genes can help us understand the effect of pesticides on many tissues. Number of sample :9 samples. We require Paired End sequencing and number of reads equal or more than 25M tags, strand specific sequencing

Project description:Post-transcriptional chemical modification of RNA bases is a widespread and physiologically relevant regulator of RNA maturation, stability, and function. While modifications are best characterized in short, noncoding RNAs such as transfer RNAs (tRNAs), growing evidence indicates that messenger RNAs (mRNAs) and long noncoding RNAs (lncRNAs) are likewise modified. Here, we apply our High-throughput Annotation of Modified Ribonucleotides (HAMR) pipeline to identify and classify modifications that affect Watson-Crick base-pairing at three different levels of the human and Arabidopsis thaliana transcriptomes (polyadenylated, small, and degrading RNAs). We find modifications primarily within actively degrading mRNAs and lncRNAs, suggesting they can act as a potent signal for RNA turnover. Additionally, modifications within stable mRNAs mark alternatively spliced introns, suggesting they regulate splicing. Furthermore, these modifications target mRNAs with coherent functions, including stress responses. Thus, our comprehensive analysis of RNA modification across multiple RNA classes yields new functional insights into these covalent RNA additions. polyA-selected RNA-seq, smRNA-seq, and polyA-selected global mapping of uncapped transcripts (GMUCT) in Arabidopsis thaliana; smRNA-seq in HEK293T and HeLa human cell lines.

Project description:The environmental factors such as pesticides could affect the developmental processes and cause the phenotypic changes. Moreover, the changes could be transferred to a subsequent generation via gametes. In this project we studied whether the pesticide chlordecone could cause the developmental effects and cause the transgenerational inheritance in outbred mouse strain. Mice were treated during development at dose 100 µg/kg/day and the progeny of exposed mice were crossed for three generations. The testes of the third generations males were used for anti-H3K4me3 ChiP-seq analysis. We used two biological replicates for each condition.

Moreover, the changes could be transferred to a subsequent generation via gametes. In this project we studied whether the pesticide chlordecone could cause the developmental effects and cause the transgenerational inheritance in outbred mouse strain (Swiss). Mice were treated during development (E6.5-E15.5) at dose 100 µg/kg/day and the progeny of exposed mice (F1) were crossed for three generations. The prostate of the first (F1) and third generation males (F3) were used for RNA-seq-analysis. We used three biological replicates for each condition.

Project description:Polycystic ovary syndrome (PCOS) is the most common endocrinological disorder of fertile-aged women. PCOS has been associated with adverse pregnancy outcomes and abnormalities of the placenta. By taking a quantitative label-free quantitative proteomics approach we set out to investigate if changes in the plasma proteome of pregnant women with PCOS could elucidate the mechanisms behind the pathologies observed in PCOS pregnancies. We have performed label-free quantitative proteomics on plasma samples from pregnant women with PCOS at term (n=14) and plasma samples from pregnant control women (n = 23) matched for age, gestational length and BMI. The samples are derived from BASIC pregnancy cohort from Uppsala, Sweden. A total of 169 proteins with two or more unique peptides were identified.
