Project description:SPO11-promoted DNA double-strand breaks (DSBs) formation is a crucial step for meiotic recombination, and it is indispensable to detect the broken DNA ends accurately for dissecting the molecular mechanisms behind. Here, we report a novel technique, named DEtail-seq (DNA End tailing followed by sequencing), that can directly and quantitatively capture the meiotic DSB 3’ overhang hotspots at single-nucleotide resolution.
Project description:T cell responses within pediatric brain tumors (PBT) remain poorly understood. We performed single-cell RNA-seq (scRNA-seq) and paired T cell receptor sequencing (TCR-Seq) of patient-derived brain tumor-infiltrating T cells to map T cell molecular profile with TCR repertoire and clonality. We demonstrate marked clonal expansion of intra-tumoral T cells and reveal their differential phenotype, transcriptional state and functional properties within brain tumors. To understand T cell responses within highly immunogenic tumors that respond to checkpoint blockers, we undertook analysis of human non-small cell lung cancer (NSCLC). We performed single-cell RNA-seq (scRNA-seq) and paired T cell receptor sequencing (TCR-Seq) of patient-derived lung tumor-infiltrating T cells to map T cell molecular profile with clonality.
Project description:Asthma is a chronic inflammatory airway disease characterized by airway inflammation and remodeling. The role of 15-oxo-5Z,8Z,11Z,13E-eicosatetraenoic acid (15-oxoETE), a 15-HETE metabolite catalyzed by 15-prostaglandin dehydrogenase (15-PGDH), has been relatively unexplored in asthma. In this study, we used RNA-seq to explore the effect of 15-KETE on the transcriptome of airway epithelial cells, aiming to identify its potential downstream targets and mechanisms of action.
