Project description:Bumblebees (Hymenoptera: Apidae) are important pollinating insects that play pivotal roles in crop production and natural ecosystem services. To achieve a comprehensive profile of accessible chromatin regions and provide clues for all possible regulatory elements in the bumblebee genome, we did ATAC-seq for Bombus terrestris samples derived from its four developmental stages: egg, larva, pupa, and adult, respectively. The sequencing reads of ATAC-seq were mapped to B. terrestris reference genome, and its accessible chromatin regions were identified and characterized using bioinformatic methods. Our study will provide important resources not only for uncovering regulatory elements in the bumblebee genome, but also for expanding our understanding of bumblebee biology.
Project description:Non-coding regulatory elements (NCRE) represent a major fraction of the human genome, play important roles in different biological pathways, and have the potential as genomic medicine targets. We developed a straightforward dual-CRISPR screening system capable of deleting thousands of NCREs genome-wide to study their functions in distinct biological contexts in K562 cells. Here we reported 4 top hits from the genome-wide screen of ultra-conserved elements (UCE), i.e. PAX6_Tarzan(chr11:31810437-31810870, hg19) and PBX3_Claudia(chr9:128457564-128457785, hg19) play essential roles in cell growth and drug response.
