Project description:miRNAs have been implicated in the regulation of a broad range of biological processes including development, immunity and inflammation We used miRNA microarray to explore the detailed biological processes and mechanisms underlying matter-induced pulmonary toxicity
Project description:To determine the epigenetic mechanism by which PM2.5 deteriorated synaptic transmission and spatial learning and memory, we determined miRNA expression in hippocampi of mice in absent or present of PM2.5 exposure using GenoExplorer microRNA microarray analysis.
Project description:To elucidate Al2O3 NPs role in recovery of soybean under flooding stress, gel-free proteomic technique was used. The proteomic analysis of root including hypocotyl at 2, and 4 days of flooding with 50 ppm Al2O3 NPs leading to subsequent removal as compared to flooding was performed.
Project description:We evaluated the profile of lncRNA and mRNA expression in control and 50μg/ml DEP treated HBE cells using the Arraystar Human LncRNA Array v3.0 array,7th generation. Our findings implicates that dysregulation of mitochondria invovled mRNAs may play important role in cytotoxicity of DEP. Examination of lncRNA and mRNA expression in control or DEP-treated HBE cells
Project description:In order to assess the alteration of lncRNA expression in 16HBE cell treated with PM2.5 samples, we determined the lncRNA expression profiles in 16HBE cell treated with PBS (control group) and PM2.5 samples (low dose 125 μg/mL and high dose 500 μg/mL) using lncRNA Microarray. 16HBE Cells were treated with PM2.5 suspension at concentration of 125 μg/mL and 500 μg/mL, and PBS was used in the control group for 48 h. Then, total RNAs were extracted for lncRNA chip preparation and analysis.
Project description:Objectives: To explore the molecular mechanisms of PM2.5-induced dysfunction in human corneal epithelial cells (HCECs). Methods: RNA-Seq was performed to identify the differentially expressed genes (DEGs) in PM2.5-exposed HCECs compared to unexposed condition, which was followed by validation via real-time PCR (qRT-PCR). Results: A total of 434 DEGs—240 up-regulated and 194 down-regulated—were identified in PM2.5-exposed HCECs rather than unexposed HCECs. The expression of a few genes related to proliferation, inflammation, and aryl hydrocarbon stimulation were significantly altered by PM2.5 exposure, which may contribute to PM2.5-related corneal diseases. Conclusion: The present study identified the altered expression of hundreds of genes in HCECs exposed to PM2.5, which suggests the importance of PM2.5 for cornea health.
Project description:Purpose: The goal of this study is to investigate the effects of fine particulate matter (PM2.5) exposure on mouse olfactory bulb using next generation sequencing (NGS). Methods: After 28 days of 3 mg/kg/3 day and 10 mg/kg/3 day PM2.5 exposure, olfactory bulb mRNA profiles of 8-week-old wild-type (WT) male C57BL/6 mice were generated by deep sequencing, in 3-4 repeats, using Illumina NovaSeq 6000. For each sample, clean reads were obtained that mapped to mm10 using HISAT2 (hierarchical indexing for spliced alignment of transcripts) v2.0.477. Results: Our study revealed that PM2.5 treatment caused significant effects on the gene expression profilling of mouse olfactory bulb. Overall, the sequencing identified 34,745 transcripts, and two kinds of treatments obtained 60 and 138 differently expressed genes (DEGs) respectively, with a criteria of fold change >2 and q-value <0.5. Most biological events that DEGs involved were inflammation relevant. Conclusions: Our study revealed that PM2.5 treatment caused significant effects on the gene expression profiling of mouse olfactory bulb.
