Single Cell Transcriptomic Analysis in a Mouse Model of Barth Syndrome Reveals Cell-Specific Alterations in Gene Expression and Intercellular Communication

Developmental gene regulation by an ancient intercellular communication system in social amoebae

Project description:In the social amoebae (Dictyostelia) quorum sensing system mediates aggregation of single cells into multicellular aggregates by chemotactic movement towards gradients of diffusible molecules known as acrasins. The acrasin of P. violaceum is the unusual dipeptide N-propionyl-gamma-L-glutamyl-L-ornithine-delta-lactam-ethylester, known as glorin. Phylogenetic analysis has indicated that P. violaceum is more related to the most derived group 4 dictyostelids than to the ancient group 2 polysphondylids such as P. pallidum. Nevertheless it has been reported that P. pallidum cells respond to glorin in chemotaxis assays. This has led to the assumption that glorin-based communication may be the most ancient form of intercellular communication that Dictyostelia invented to organize early steps of multicellular development. In this study we show that glorin mediates rapid changes in gene expression at the transition from vegetative growth to aggregation, apparently without pronounced cross-talk with the cyclic AMP-based communication system that coordinates post-aggregation events in this species. We describe glorin-mediated changes in gene expression in the social amoeba Polysphondylium pallidum at the transition from unicellular growth to multicellular development. Comparison of gene expression in growing cells versus cells starving for 2 or 3 hours in the presence or absence of glorin.

Cancer cell-endothelial intercellular transfer alters the endogenous miRNA profile and phenotype of recipient endothelial cells

Project description:Metastasis is a major cause of mortality, and remains a final frontier in the search for a cure for cancer. While there has been much research on the ‘seed’ (metastatic tumor cells) and the ‘soil’ (colonized host tissue), interactions between metastatic cancer cells and stromal endothelial cells, which occur at multiple stages during metastasis, are less well understood. Here we report a dynamic regulation of the endothelium by cancer cells through the formation of nanoscale intercellular membrane bridges, which act as physical conduits for intercellular communication in vitro and in vivo, including horizontal transfer of microRNAs (miRNA). The communication between the tumor cell and the endothelium upregulates markers associated with pathological endothelium, which is reversed by pharmacological inhibition of these nanoscale conduits. These results lead us to define the notion of “metastatic hijack”: cancer cell-induced transformation of healthy endothelium into pathological endothelium via horizontal communication through the nanoscale conduits. Pharmacological perturbation of these nanoscale membrane bridges decreases metastatic foci in syngeneic- and human xenograft-breast cancer models. Targeting the formation of these nanoscale membrane bridges may potentially emerge as a new therapeutic opportunity in the management of metastatic cancer. A miRNA microarray was used to evaluate the transport of endogenous microRNAs. The intercellular transfer-ve and intercellular transfer+ve samples were sorted from the same endothelial cell population with the only difference being the occurrence of intercellular transport. The heat map shows potential miRNA candidates for exogenous transfer on two independent biological replicates. These miRNA candidates were significantly up-regulated in the cells receiving transfer of intercellular contents. HUVECs that were not exposed to cancer cells were used as a baseline control.

Adolescent bone sarcomas have distinct immune signatures and intercellular communication networks

Project description:Ewing and osteosarcoma are bone sarcomas that occur predominantly in adolescents. In the setting of metastatic or recurrent disease, overall prognosis is poor. While immunotherapy is effective for some adult soft tissue sarcoma, limited success has been achieved with immunotherapy for pediatric bone sarcomas. To better understand antitumor immunity in Ewing and osteosarcoma patients, we performed single-cell RNAseq on peripheral blood and tumor infiltrating immune populations using 10X Genomics droplet-based approach. We also included peripheral blood from healthy adolescent blood donors as a comparator. Utilizing these transcriptional profiles, we characterized tumor infiltrating CD8+ T cells and myeloid cells and identified intercellular communication networks in both primary and recurrent disease.

Reconstruction of intercellular communication and signaling impacting de novo HSC emergence using CellComm platform

Project description:Cellular transitions are shaped by cross-talk between cell-intrinsic and extrinsic factors. Signals derived from the cell’s microenvironment are integrated and processed by the cell to modulate gene expression programs to instruct cell function and fate. Recent advances in single-cell technologies and analytics have provided an unprecedented resolution to study intercellular communication and differentiation trajectories. Here, we developed CellComm, a systems biology platform to infer intercellular communication networks and transcriptional regulators downstream of cell surface receptors predicted to mediate cellular interactions. We applied CellComm to investigate how the unique cellular niche of the aorta-gonad-mesonephros (AGM) region is involved in hematopoietic stem cell emergence and identified key cell types and microenvironmental signals implicated in hematopoietic development. We extensively validated CellComm’s predictions in three different species - zebrafish, mouse and human - and found both known and novel genes involved in developmental hematopoiesis, such as Stat3, Nr0b2, Ybx1 and, surprisingly, App, which is often reported in neurodegenerative disorders. Strikingly, CellComm revealed extensive cross-talk of signaling pathways feeding into the same transcriptional regulators, indicating a tightly regulated developmental program ensuring dynamic adaptation to changes in the embryonic environment. Taken together, our work contributes to a better understanding on how the embryonic niche is involved in developmental hematopoiesis as well as provides a new algorithm and data resource for the scientific community.

Inferring pattern-driving intercellular flows from single-cell transcriptomics of young human cortical organoids

Project description:Intercellular communication drives directed flows of information that are mediated by intracellular gene modules, in turn triggering outflows of other signals. Methodologies to describe such intercellular flows are severely lacking. We present FlowSig, a method that infers communication-driven intercellular flows from scRNA-seq using graphical causal modeling and conditional independence. We used human cortical organoid samples collected at D18 and D35 to demonstrate the functions of FlowSig.

Dissection of intercellular communication using the transcriptome-based framework ICELLNET

Project description:Cell-to-cell communication can be inferred from ligand-receptor expression in cell transcriptomic datasets. However, important challenges remain: 1) global integration of cell-to-cell communication, 2) biological interpretation, and 3) application to individual cell population transcriptomic profiles. We develop ICELLNET, a transcriptomic-based framework integrating: 1) an original expert-curated database of ligand-receptor interactions accounting for multiple subunits expression, 2) quantification of communication scores, 3) the possibility to connect a cell population of interest with 31 reference human cell types, and 4) three visualization modes to facilitate biological interpretation. We apply ICELLNET to 3 datasets generated through RNA-seq, single-cell RNA-seq, and microarray. ICELLNET reveal autocrine IL-10 control of human dendritic cell communication with up to 12 cell types. Four of them (T cells, keratinocytes, neutrophils, pDC) are further tested and experimentally validated. In summary, ICELLNET is a global, versatile, biologically validated, and easy-to-use framework to dissect cell communication from individual or multiple cell-based transcriptomic profile(s).
