Project description:We obtained HBV-infected liver tissues from liver surgery(AST<40) and liver transplantation(AST>40) to perform next-generation sequencing (NGS). Illumina mRNA-seq sample preparation kit was used to perform paired-end library sequencing with Illumina HiSeq 2000 and sequence analysis was determined using the Illumina data analysis pipeline. Based on the comparison results, we performed the GO and KEGG pathway enrichment analysis. That might suggest the different status of HBV-infected liver from liver surgery(AST<40) and liver transplantation(AST>40).
Project description:The goals of this study are to compare NGS-derived transcriptome profiling (RNA-seq) of Seminavis robusta in presence and absence of associated bacterial spent medium (Maribacter sp. and Roseovarius sp.) in order to highlight the effect of bacterial exudates on diatom gene expression and metabolic processes.
Project description:We performed comparative transcriptomic analysis of the outer membrane vesicles (OMVs) released from B. burgdorferi. We identified a total of ~1200 unique transcripts with at least one mapped read from the bacterial cell and its OMVs.
Project description:In this study, we performed a comparative analysis of gut microbiota composition and gut microbiome-derived bacterial extracellular vesicles (bEVs) isolated from patients with solid tumours and healthy controls. After isolating bEVs from the faeces of solid tumour patients and healthy controls, we performed spectrometry analysis of their proteomes and next-generation sequencing (NGS) of the 16S gene. We also investigated the gut microbiomes of faeces from patientsand controls using 16S rRNA sequencing. Machine learning was used to classify the samples into patients and controls based on their bEVs and faecal microbiomes.
Project description:The amygdalostriatal transition zone (ASt) is anatomically poised to provide a shortcut between corticolimbic and basal ganglia circuitry, and mediate behavioral responses to stimuli in parallel with the amygdala. Like the amygdala, the ASt receives converging sensory input from thalamic and cortical pathways. However, the projections of the ASt are distinct from canonical outputs of the amygdala complex, and are integrated with striatal circuits involved in action selection. Despite this intriguing circuit connectivity, the function of the ASt is almost completely unknown. In the present study, we collected cellular resolution recordings of genetically-defined neurons during a valence discrimination task to interrogate the functional role of ASt circuitry, and characterized the transcriptomic profile of the ASt in comparison to neighboring regions. We find that ASt neurons, and specifically, ASt neurons expressing dopamine receptor 2 (D2+), robustly encode sustained conditioned responses to cues of negative valence. Selective inhibition of D2+ ASt neurons was found to cause a striking reduction in conditioned fear responses. We also used single-nucleus RNA sequencing to generate a comprehensive profile of gene expression in ASt neurons, and found that the ASt is genetically distinct from adjacent GABAergic brain regions. RNAscope labelling also confirmed there is a greater proportion of D2+ neurons than D1+ neurons in the ASt, a unique feature compared to other regions of the striatum. Together, our findings provide the first evidence the ASt is a critical structure for encoding learned associations to direct motivated behavior.
Project description:Origanum oil (ORO), garlic oil (GAO), and peppermint oil (PEO) were shown to effectively lower methane production, decrease abundance of methanogens, and change abundances of several bacterial populations important to feed digestion in vitro. In this study, the impact of these essential oils (EOs, at 0.50 g/L), on the rumen bacterial community composition was further examined using the recently developed RumenBactArray.
Project description:we identified novel age-related microRNAs through comparative analysis of miRNA expression profiles in young and old myoblasts using next generation sequencing (NGS)
