Project description:In order to understand the genomic and transcriptomic variability of the axolotl pallium, as well as reconstruct their intrinsic gene regulatory networks, we performed single-nucleus multiome sequencing (RNA and open chromatin) of whole axolotl pallium.
Project description:Despite significant progresses, the genetic roles of regulatory elements in gene expression still remain largely unknown in prostate cells. Recent development in single cell sequencing has made it possible to combine ATAC-seq and RNA-seq to determine genome-wide linkages between chromatin accessibilities and gene expression. To test the feasibility of using single cell multiome sequencing in dissecting regulatory linkages between chromatin accessibilities and gene expressions, we applied 10X Multiome ATAC + Gene Expression platform to simultaneously encapsulate Tn5 transposase tagged nuclei from multiple prostate cell lines. Based on these multiomic data, we developed subsampling linkage analysis to identify linkage associations between open chromatin and gene expressions. Moreover, we implemented an innovative analytical method to investigate RNA expression alterations related to germline variant locus accessibilities at single cell levels, i.e., expression quantitate accessible loci (eQAL) analysis. Our data and methodology will complement traditional eQTL analysis and foresee more genetic applications aiming to clarify regulatory elements by single cell sequencing.
Project description:To study the effect of GLI3 knockout on early brain organoid development, we collected single-cell multiome data from 18 day old brain organoids
Project description:We report the single nucleus multiome (RNAseq+ATACseq) of a male mouse pituitary sample. This dataset was generated for supporting the development of a novel computational framework for analyzing gene regulatorty circuitry from single cell multiome datasets. This computational framework extract regulatory circuits consisting of TFs, cis-regulatory sites and target genes by modelling the co-incidence of the RNA levels of the TFs, the chomatin accessibility of the TFs' binding sites and the RNA levels of target genes across single cell. Specifically we identified gonadotrope-specific regulatory circuits under the transcription factor Gata2. These regulatory circuits were validated by male mouse pituitary samples with gonadotrope-conditional knockout of Gata2 previously reported in GSE190066.
