Project description:we mapped the locations of DNA segments occupied by GATA1 using chromatin immunoprecipitation (ChIP). We have produced genome-wide GATA1 ChIP datasets after restoration and activation in G1E-ER4 cells. we employed the sequence census methodology of ChIP-seq , using Illumina GA2 technology to produce 23 million reads (36 nucleotides long) uniquely mapped to the mouse genome (mm8 assembly) for the GATA1 ChIP DNA and 15 million mapped reads for the input DNA Examination of transcription factor GATA1 occupancy
Project description:Census of apparent proteome unfolding curves following urea denaturation in cell lysate derived from control of VER155008-treated N2a cells using thiol reactivity probe tetraphenylethene maleimide (TPE-MI).
Project description:We performed single-cell RNA-sequencing to create a cell census of the human endometrium, which is the mucosal lining of the uterus that undergoes dynamic changes throughout the menstrual cycle. We integrated cells that were obtained from 3 superficial biopsies to selected samples that originated from 2 organ donors; this allowed a better representation of cell type diversity found within the full depth of the endometrium.
Project description:In healthy skin, a cutaneous immune system maintains balance between tolerance towards innocuous environmental antigens and immune responses against pathological agents, but in atopic dermatitis (AD), barrier and immune dysfunction result in chronic tissue inflammation. Our understanding of the skin tissue ecosystem in AD remains incomplete, including pathological barrier formation, and cellular state and clonal composition of disease-promoting cells. Here, we generated a multi-modal cell census of 310,691 cells from 86 cell subsets from whole skin tissue of 19 adult individuals, including non-lesional and lesional skin from 11 AD patients, and integrated it with 396,321 cells from 4 studies into a comprehensive atlas. Lesional skin comprised a unique immune and stromal multicellular community that included populations of MMP12+ DCs, mature migratory DCs, cycling ILCs, NK cells, inflammatory CCL19+ IL4I1+ fibroblasts, and clonally expanded IL13+IL22+IL26+ T cells with overlapping type 2 and type 17 characteristics, connected by multiple inter-cellular positive feedback loops. Reconstruction of human keratinocyte differentiation from basal to cornified layers revealed a disrupted cornification trajectory in AD associated with signals from the disease-associated immune compartment. AD GWAS gene expression was enriched in cornified keratinocytes, IL13+IL22+IL26+ T cells, and ILCs, suggesting that epithelial or immune dysfunction can initiate and then converge towards AD. Our work highlights specific, disease-associated cell subsets and interactions as potential targets in progression and resolution of chronic inflammation.
