Project description:To elucidate the molecular mechanism underlying lifespan reduction induced by PM2.5 exposure in Caenorhabditis elegans, we performed global gene expression profiling by RNA-sequencing technology, and compared the gene expression pattern change induced by PM2.5 exposure.
Project description:The C. elegans lifespan in the presence of Bacillus licheniformis caused induction of a large number of genes associated with anti-aging activiy including beta-oxidation Inaddition, these results indicate the B. licheniformis enhances the lifespan of Caenorhabditis elegans through serotonin signaling
Project description:The C. elegans lifespan in the presence of Bacillus licheniformis caused induction of a large number of genes associated with anti-aging activiy including beta-oxidation Inaddition, these results indicate the B. licheniformis enhances the lifespan of Caenorhabditis elegans through serotonin signaling Two-condition experiment, C. elegans with B. lichemiformis 141 or E. coli OP50 (conrol) for 24 h. For preparing the total RNA, C. elegans were exposed to 20 mg of bacterial lawn in NGN agar for 24 h.
Project description:Genome-wide analysis of lncRNA expression profiles in COPD rat model exposed by cigarette smoking (CS) and fine particulate matter (PM2.5). Goal was to explore the differences and similarities lncRNAs expression in rats model of COPD exposed by CS and PM2.5.
Project description:The animals were divided into two groups according to exposure of PM2.5 (particulate matter less than 2.5 µm): control group (Non-PM group) or PM exposure group (PM group).PM2.5 at 150 μg/m3were administered by intratracheal instillation during the gestation period of female rats from Day 1 of conception onwards.After the female rat gave birth,the offspring's heart DNA was extracted and anlyzed. DNA promotor methylation profile were determined.The goal was to determine the effects of PM2.5 exposure on the DNA promotor methylation patterns in heart tissue.
Project description:Exposure to PM2.5 affects gene expression of BEAS-2B cells Gene expression microarrays were used to detail changes in the transcriptome upon exposure to PM2.5
Project description:we used Caenorhabditis elegans as a model organism, to investigate the effect of mannose on the lifespan. Using nematode RNAi methods, RT-PCR, RNA-seq and other experimental method, we explored the possible mechanism for how mannose change the lifespan of Caenorhabditis elegans.
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.
