Single-cell ID-seq identifies BMP signaling as a driver of a late stage epidermal differentiation program

ABSTRACT: We developed a single cell application of the sequencing-based immunodetection method ID-seq which makes it possible to multiplex measurements of many different epitopes from proteins and phosphoproteins in a high throughput setting. A FACS sort step was implemented to allow sorting of single cells in 96 well plates. With these DNA-tagged antibodies and dedicated sample preparation protocol adapted for single cells, we studied the studied the changes of 70 (phospho-)proteins in primary human skin cells compared to a subpopulation with low ITGB1 protein expression. Given that ITGB1 is a skin stem cell marker, we indeed found that the ITGB1 low cells are differentiated and we found a role for BMP signaling in this process.

Project description:We developed a sequencing-based immunodetection method which makes it possible to multiplex measurements of many different epitopes from proteins and phosphoproteins in a high throughput setting. With these DNA-tagged antibodies and dedicated sample preparation protocol, we studied the effect of hundreds of kinase inhibitors on 70 (phospho-)proteins in primary human skin cells.

Oncogenic herpesvirus KSHV Hijacks BMP-Smad1-Id signaling to promote tumorigenesis.

Project description:Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiological agent of Kaposi's sarcoma (KS), a malignancy commonly found in AIDS patients. Whether KS is a true neoplasm or hyperplasia has been a subject of intensive debate until recently when KSHV is unequivocally shown to efficiently infect, immortalize and transform rat primary mesenchymal precursor cells (MM). Moreover, KSHV-transformed MM cells (KMM) efficiently induce tumors with hallmark features of KS when inoculated into nude mice. Here, we showed Smad1 as a novel binding protein of KSHV latency-associated nuclear antigen (LANA). LANA interacted with and sustained BMP-activated p-Smad1 in the nucleus and enhanced its loading on the Id promoters. As a result, Ids were significantly up-regulated in KMM cells and abundantly expressed in human KS lesions. Strikingly, genetic and chemical inhibition of the BMP-Smad1-Id pathway blocked the oncogenic phenotype of KSHV-transformed cells in vitro and in vivo. These findings illustrate a novel mechanism by which a tumor virus hijacks and converts a developmental pathway into an indispensable oncogenic pathway for tumorigenesis. Importantly, our results demonstrate the efficacy of targeting the BMP-Smad1-Id pathway for inhibiting the growth of KSHV-induced tumors, and therefore identify the BMP pathway as a promising therapeutic target for KS.

BMP-SMAD-ID promotes reprogramming to pluripotency by inhibiting p16/INK4A-dependent senescence.

Project description:Fibrodysplasia ossificans progressiva (FOP) patients carry a missense mutation in ACVR1 [617G > A (R206H)] that leads to hyperactivation of BMP-SMAD signaling. Contrary to a previous study, here we show that FOP fibroblasts showed an increased efficiency of induced pluripotent stem cell (iPSC) generation. This positive effect was attenuated by inhibitors of BMP-SMAD signaling (Dorsomorphin or LDN1931890) or transducing inhibitory SMADs (SMAD6 or SMAD7). In normal fibroblasts, the efficiency of iPSC generation was enhanced by transducing mutant ACVR1 (617G > A) or SMAD1 or adding BMP4 protein at early times during the reprogramming. In contrast, adding BMP4 at later times decreased iPSC generation. ID genes, transcriptional targets of BMP-SMAD signaling, were critical for iPSC generation. The BMP-SMAD-ID signaling axis suppressed p16/INK4A-mediated cell senescence, a major barrier to reprogramming. These results using patient cells carrying the ACVR1 R206H mutation reveal how cellular signaling and gene expression change during the reprogramming processes.

Gene expression profiling of mouse embryonic stem cells with single-cell RNA sequencing

Project description:Differences in gene-expression profiles between individual cells can give rise to distinct cell fate decisions. Yet how localisation on a micropattern impacts initial changes in mRNA, protein, and phosphoprotein abundance remains unclear. To identify the effect of cellular position on gene expression, we developed a scalable antibody and mRNA targeting sequential fluorescence in situ hybridization (ARTseq-FISH) method capable of simultaneously profiling mRNAs, proteins, and phosphoproteins in single cells. We studied 67 (phospho-)protein and mRNA targets in individual mouse embryonic stem cells (mESCs) cultured on circular micropatterns. To validate the detection of the mRNA targets quantified with ARTseq-FISH, we utilized single-cell RNA sequencing to profile a comparable population of mouse embryonic stem cells.

scRNASeq data of CD45+CD3-CD19- and keratinocytes in normal and HS skin

Project description:Hidradenitis suppurativa (HS) is a highly prevalent, morbid inflammatory skin disease with limited treatment options. The major cell types and inflammatory pathways in skin of HS patients are poorly understood. We profiled via scRNASeq myeloid cells and keratinocytes sort-purified from two healthy skin samples and two samples with HS pathology to determine major cell types and transcriptional pathways altered in HS.

Single-Cell ID-seq Reveals Dynamic BMP Pathway Activation Upstream of the MAF/MAFB-Program in Epidermal Differentiation.

Project description:Epidermal homeostasis requires balanced and coordinated adult stem cell renewal and differentiation. These processes are controlled by both extracellular signaling and by cell intrinsic transcription regulatory networks, yet how these control mechanisms are integrated to achieve this is unclear. Here, we developed single-cell Immuno-Detection by sequencing (scID-seq) and simultaneously measured 69 proteins (including 34 phosphorylated epitopes) at single-cell resolution to study the activation state of signaling pathways during human epidermal differentiation. Computational pseudo-timing inference revealed dynamic activation of the JAK-STAT, WNT, and BMP pathways along the epidermal differentiation trajectory. We found that during differentiation, cells start producing BMP2-ligands and activate the canonical intracellular effectors SMAD1/5/9. Mechanistically, the BMP pathway is responsible for activating the MAF/MAFB/ZNF750 transcription factor network to drive late-stage epidermal differentiation. Our work indicates that incorporating signaling pathway activation into this transcription regulatory network enables coordination of transcription programs during epidermal differentiation.

A global transcriptome analysis of human dermal fibroblasts upon knockdown or overexpression of the circular RNAs circGLIS3 (circBase ID: hsa_circ_0002874)

Project description:In an RNAseq analysis, we have identified circGLIS3 with high levels acute wound dermis compared to skin. The biological function of circGLIS3 in human dermal fibroblasts during wound repair has not been studied. To study the genes regulated by circGLIS3, we transfected siRNA or plasmid into human dermal fibroblasts to knockdown or overexpress circGLIS3. We performed a global transcriptome analysis of fibroblasts upon circRNA knockdown or overexpression using Affymetrix arrays.
