Compendium of Disease-Linked Regulatory DNA Variants and Homeostatic Transcription Factors in Epidermis [crispr_flow]

ABSTRACT: Identifying the regulatory noncoding single nucleotide variants (SNVs) linked to polygenic disease risk, the transcription factors (TFs) they bind, and the target genes they dysregulate is a current focus in many tissues. Massively parallel reporter gene analysis (MPRA) of 3,451 SNVs linked to risk for prevalent human skin diseases identified 355 differentially active SNVs (daSNVs). daSNV target gene analysis, including genomic editing at three loci, highlighted dysregulated epidermal differentiation as a common pathomechanism. CRISPR knockout screens of 1,782 human TFs identified 108 TFs essential for epidermal homeostasis, validating new roles for ZNF217, CXXC1, FOXJ2, IRX2 and NRF1. Population sampling CUT&RUN from 310 samples of 27 homeostatic TFs across differentiation identified allele-specific binding differences enriched near epidermal homeostasis and monogenic skin disease genes, with prominent representation of SP/KLF and AP-1/2 family TFs. This resource indicates that dysregulated differentiation underlies pathogenic risk for diverse polygenic skin diseases.

Inherited functional regulatory risk variants for common human cancers

Project description:Single nucleotide variants (SNVs) in regulatory DNA are linked to inherited cancer risk. Massively parallel reporter assays (MPRA) of 5,031 SNVs linked to 14 neoplasms comprising >90% of human malignancies were performed in pertinent diploid cell types then integrated with matching chromatin accessibility, looping, and eQTL data to identify 411 regulatory SNVs and their putative target eGenes. The latter highlighted specific protein networks in lifetime cancer risk, including mitochondrial translation, proliferation, signaling, adhesion, and immunity. This cancer SNV compendium underscores the importance of studying pathogenic variants in disease-relevant cells and implicates specific dysregulated gene networks in cancer predisposition. It also indicates that inherited cancer risk can impact the same gene via orthogonal genetic mechanisms of dysregulated expression as well as protein coding sequence alteration and demonstrates that a subset of germline-encoded risk genes also enable tumor growth of established cancers.

Atopic dermatitis complicated by recurrent eczema herpeticum is characterized by multiple, concurrent epidermal inflammatory endotypes

Project description:A subgroup of atopic dermatitis (AD) patients suffers from recurrent, disseminated herpes simplex virus (HSV) skin infections, eczema herpeticum (EH). To determine transcriptional mechanisms of the skin and immune system pathobiology that underlies ADEH disease development, we performed RNA-sequencing analysis of non-lesional skin (epidermis, dermis) from AD patients with (ADEH+, n=15) and without (ADEH-, n=13) history of EH, and healthy controls (HC, n=15). We also performed RNA-sequencing on participants’ plasmacytoid dendritic cells (pDCs) infected in vitro with HSV-1. ADEH+ patients exhibited dysregulated gene expression, limited in dermis (differentially expressed genes [DEGs]=14) and more widespread in epidermis (DEGs=129). ADEH+-upregulated epidermal DEGs were enriched in type 2 cytokine (T2) (IL4R, CCL22, CRLF2, IL7R), interferon (CXCL10, ICAM1, IFI44, IRF7), and IL-36γ (IL36G) inflammatory gene pathways. All ADEH+ participants exhibited T2 and interferon endotypes and 87% were IL36G-high. In contrast, these endotypes were more variably expressed among ADEH- participants. ADEH+ skin also dysregulated epidermal differentiation complex (EDC) gene expression within LCE, S100, and SPRR families, which are involved in skin barrier function and antimicrobial activities. pDC transcriptional responses to HSV-1 infection were unaltered by ADEH status. Pathobiology underlying ADEH+ risk is associated with a unique, multi-faceted epidermal inflammation that accompanies dysregulation of EDC genes. These findings will help direct future studies that define how these inflammatory patterns may drive risk of eczema herpeticum in AD.

Conditional keratinocyte-specific ADAM17 knockout in mice alters skin homeostasis

Project description:This study investigates the role of ADAM17 (a disintegrin and metalloproteinase 17) in skin homeostasis. Here, we show that mice lacking ADAM17 in keratinocytes have a normal epidermal barrier and skin architecture at birth, but develop pronounced defects in epidermal barrier integrity soon after birth and chronic dermatitis as adults. The dysregulated expression of epidermal differentiation proteins becomes evident 2 days after birth, followed by transepidermal water loss and inflammatory immune cell infiltration. Our results identify a previously unappreciated critical role of the ADAM17/EGFR signaling axis in maintaining the homeostasis of the postnatal epidermal barrier. The genome-wide effects of ADAM17 deficiency were analyzed using Agilent Whole Mouse Genome microarrays. Conditional keratinocyte-specific ADAM17 knockout mice were generated by crossing Adam17flox/flox mice with keratin-14-Cre (Krt14-Cre) transgenic mice. Adam17flox/+Krt14-Cre mice were mated with Adam17flox/flox mice to generate pups of Adam17flox/flox Krt14-Cre positive (cKO) and Krt14-Cre negative (wild-type) control littermates. The genetic background was a mix of 129Sv and C57BL/6. As material, back skin tissue biopsies (postnatal day 10) from n = 2 wild-type skin and n = 2 ADAM17 epidermal KO skin (matched WT-cKO pairs from two different litters) were used in this study.

Alteration of keratinocyte gene expression as a result of Flg deficiency

Project description:Defects of filaggrin (FLG) compromise epidermal barrier function and represent an important known genetic risk factor for atopic dermatitis (AD), but also for systemic atopy, including allergic sensitization and asthma. A loss of epidermal barrier integrity can provide a significant stress for the keratinocytes in the skin, either due to the increased moisture evaporation from the skin or increased penetration of the antigens and microflora into the lower epidermal layers. To understand the effect of this loss of barrier integrity on keratinocyte function our aim is to analyze the alterations in the transcriptional profile of keratinocytes from Flg-deficient mice.
