Project description:To address the roles of PML bodies in transcription under stress condition, we performed ALaP-seq and RNA-seq with paraquat treated mESCs.
Project description:Transcriptional profiling of A. oleivorans DR1 cells in the presence of paraquat and phenazine methosulfate To identify genes involved in oxidative stress response in A. oleivorans DR1, cells were grown to exponential phase (OD600 ~0.4) and treated with paraquat (1 mM) and phenazine methosulfate (200 μM) over a period of 15 min. Total RNA was extracted using an RNeasy Mini kit (Qiagen, USA) following the manufacturer's instructions.
Project description:PURPOSE: Pulmonary fibrosis (PF) is a pathological state presenting at the progressive stage of heterogeneous interstitial lung disease (ILD). The molecular mechanisms are incompletely understood. We built a mouse model of lung fibrosis induced by paraquat. Using transcriptome analysis, we identified differentially expressed proteins (DEGs) and provided further functional analysis. METHODS: We built a mouse model of lung fibrosis through intratracheal instillation of paraquat. After instillation, mice were kept for 7 and 28 days, respectively. we performed time-series RNA sequencing (RNA-Seq) on the lung samples from paraquat treated mice and saline control. The DEGs were verified by qPCR. RESULTS: The transcriptome data found a total of 1345 of differentially expressed genes (DEGs) up-regulated and 844 DEGs down-regulated significantly in paraquat group on day 7. There were 511 DEGs up-regulated and 179 DEGs down-regulated remarkably on day 28 after PQ instillation (Fold Change ≥2 and Q value ≤0.001). We verified 6 significantly changed genes by qPCR, proving the accuracy of RNA-seq. CONCLUTION: Our transcriptomic study assigns genes for fibrogenesis and reveals their dynamic changes from lung injury to repair, providing new insights for the and development of biomarkers and treatment in fibrotic diseases.
Project description:We use RNAseq to compare the transcriptomes of wild type and cells treated with 2.5 mM paraquat (PQ) for 8 hr. We find that PQ treatment results in changes in the transcripts for hundreds of genes. A notable subset of PQ-induced transcripts encodes proteins activated by the retrograde response pathway. This pathway is activated by ETC dysfunction and regulates carbohydrate metabolism to increase synthesis of biosynthetic intermediates through pathways including the TCA cycle, glutamine biosynthetic pathway, and isocitrate metabolism. Transcripts encoding oxidative stress response proteins (e.g. amino acid and iron transporters and siderophores) are also more abundant in PQ-treated cells.
Project description:We report RNA-sequencing from ventral mid brain and striatum from paraquat, pyridaben and paraquat+maneb mice models of Parkinson's disease. We observed several differentially expressed genes upon pesticide exposure which we analyzed by pathway analysis. We examined 3 replicates each for ventral mid brain and striatum per pesticide for RNA-Seq
