Project description:We wished to examine the effect that coculture with Desemzia incerta would have on the S. aureus transcriptional profile. We have previously shown D. incerta to have antimicrobial activity against S. aureus. We used a transwell coculture system to separate the two bacterial cultures. Transcriptional profiling revealed downregulated of genes in the arc operon, the pur operon, the mnh family proteins, and cap family proteins and upregulations in the arg operon and the ahp opeorn. Subsequent biological follow-up revealed decrease in S. aureus biofiom formation after D. incerta co-culture.

Project description:This study examined NAc gene expression in a pair short-term selected lines bred for high or low response to methamphetamine (MA). We sought to identify candidate genes preferentially expressed among individuals showing either large or small acute responses to MA. Additionally, we sought to identify genes and networks differentially expressed by MA exposure within these divergent lines. Keywords: Short-term selected lines (STSLs), saline (SAL), methamphetamine (MA), nucleus acumbens (NAc)

Project description:Liver tissues of Guangxi Ma chicken from 32-week old with m performance, 50-week old with high and low laying performance, and 72-week old with high and low laying performance were collected and sequenced in quadruplicate using RNA-seq. The sequences were double-ended sequenced on the DNBSEQ sequencing platform. The sequence reads were quality controlled and then aligned with genomic sequences using HISAT2 program, quantified by featureCounts program, and gene expression levels were verified by qRT-PCR with SYBR Green detection. The results will be helpful to explore the factors that affecting laying performance from the perspective of yolk synthesis and provide a theoretical basis for improving the egg production of Guangxi Ma chicken.

Project description:This study examined NAc gene expression in a pair short-term selected lines bred for high or low response to methamphetamine (MA). We sought to identify candidate genes preferentially expressed among individuals showing either large or small acute responses to MA. Additionally, we sought to identify genes and networks differentially expressed by MA exposure within these divergent lines. Experiment Overall Design: STSLs generated from C57BL/6J x DBA/2J stock were bred for high (HMACT) or low (LMACT) acute MA response. Mice were given a challenge injection of MA or SAL, and decapitated 1 hr later. NAc gene expression was assessed.

Project description:We conducted whole-genome bisulfite sequencing (WGBS) of Arabidopsis thaliana mutation accumulation (MA) lines under different temperature treatments over sucessive generations, and then we identified the global methylation in each MA line. Our result showed taht DNA methylation was observed more frequently at DNA mutation sites, indicating its contribution to the mutation process at elevated temperatures.

Project description:The Atlantic killifish (Fundulus heteroclitus) is an ideal model species to study physiological and toxicological adaptations to stressors. Killifish inhabiting the PCB-contaminated Superfund site in New Bedford Harbor, MA (NBH) have evolved resistance to toxicity and activation of the aryl hydrocarbon receptor (AHR) signaling pathway after exposure to PCBs and other AHR agonists. Until recently, a lack of genomic information has limited efforts to understand the molecular mechanisms underlying environmental adaptation to stressors. The advent of high throughput sequencing has facilitated an unbiased assessment of coding as well as non-coding RNAs in any species of interest. Among non-coding RNAs, microRNAs (miRNAs) are important regulators of gene expression and play crucial roles in development and physiology. The objective of this study is to catalog the miRNAs in killifish and determine their expression patterns in the embryos from contaminated (NBH) and pristine (Scorton Creek, MA (SC)) sites. Embryos from NBH and SC were collected daily from 1 to 15 days post-fertilization and RNA from pooled samples from each site was sequenced using SOLiD sequencing. We obtained 7.5 and 11 million raw reads from pooled SC and NBH samples, respectively. Analysis of the sequencing data identified 216 conserved mature miRNA sequences that are expressed during development. Using the draft killifish genome, we retrieved the miRNA precursor sequences. Based on the capacity of these putative precursor sequences to form the characteristic hairpin loop (assessed using RNAfold), we identified 197 conserved miRNA sequences in the genome.
