Project description:This study investigates transcriptomic responses of Atlantic salmon lice, Lepeophtheirus salmonis exposed to cypermethrin, a commonly used antiparasitic agent used in aquaculture. Copepodid L. salmonis were exposed to cypermethrin (Betamax®) at a concentration of 1.0ppb An in vitro bioassay experiment was conducted using cypermethrin exposures on copepodid (larvae) sea lice (F1 generation) collected from BMA-2a New Brunswick, Canada in 2014. The bioassay exposed copepodids to 1.0 μg/L cypermethrin or a sea water control for 24 hours in glass beakers (VWR) at 12 ± 1oC. Each condition had a total volume of 500mL with six replicates and approximately 500 lice per beaker. After 24 hours, pools of ~500 copepodids were flash frozen for RNA extractions. Post 24-hours, lice were assessed for survival similarly to the technique used for staging and enumeratio first
Project description:Single-cell RNA-seq of first-, second-, and third-generation patient-derived organoids. Obtained using the 10X Genomics single-cell 3' expression solution (v3 chemistry). First- and second-generation PDOs from one patient and first-, second-, and third-generation PDOs from three additional patients.
Project description:Temporal regulation of gene expression is essential for early embryonic development. With the development of next-generation sequencing technologies, transcriptional profiling of early developmental processes in various vertebrates are already revealed. However, overall transcriptome analysis of early embryonic development in avian have never been investigated. In this study, to our knowledge, we provide comprehensive profiling of pre-oviposited embryos in chicken by whole-transcriptome RNA-seq for the first time. We demonstrated the presence of avian-specific mechanism of first- and second-wave of zygotic genome activation (ZGA). Chicken early embryo have distinct developmental programs between cleavage and area pellucida formation period. Additional speculation of epigenetic dynamics indicate that maternal-to-zygotic transition (MZT) in chicken is promoted after second-wave of ZGA, through EGK.VI to EGK.X stages. These extensive results contribute to understanding avian early embryogenesis and comparative studies with other species with many developmental aspects.
Project description:We sequenced the transcriptome of gentamicin induced renal regeneration in adult zebrafish. Specifically, zebrafish kidney tissues in the first, third, fifth and seventh days of kidney injury and the control group were selected. Each sample contains three kidneys. Three samples were taken in each period, and then the total RNA of the kidney was extracted for second-generation sequencing.
