Transcriptome profiling of in vitro cellular entities involved in lung tumour fusion events

ABSTRACT: Cell fusion theory for explaining metastasis origin has been hypothesised for almost one-hundred years, mainly availed with data coming from patients who received a bone marrow transplant and all had tumour cells with DNA from their cancer-free donors. In fact, colonisation of distant organs by an original tumour could be explained with the acquisition of hallmarks from both immune and tumour parents. Here, we systematically conducted in vitro fusions between CD14+human monocytes and GFP+H60 lung tumour cells. Transcriptome analysis of naïve monocytes, and sorted GFP+, CD14+ and CD14+GFP+ cells showed the latter sharing common pathways with both parental types, which sustain their in vivo metastatic characteristics, such as mobility and invasiveness. Altogether, our data demonstrates that differentially genes profile acquisition by hybrids enables them to drive metastasis.

Methylation state of latent and proliferative metastatic tumor cells

Project description:During metastasis, cancer cells travel the circulation to colonise distant sites. Due to the rarity of these events, the immediate cell fate decisions of metastasising tumour cells (mTC) are poorly understood and the role of the endothelium, as dissemination interface, remains elusive. Using a novel combinatorial mTC enrichment approach, we provide a first transcriptional blueprint of the early colonisation process

RNA-seq profiling in CD14+ cells isolated from rhesus macaques vaccinated with V1-deleted DNA/ALVAC/gp120 vaccine

Project description:We analyzed innate and adaptive immune responses elicited by the V1-deleted DNA/ALVAC/gp120/alum vaccine in non-human primates. Following SIVmac251 challenge exposure, we observed reduced risk of SIV acquisition comparing vaccinated animals to controls, confirming th ability of this vaccine strategy in decreasing the risk of SIV acquisition against vaginal exposure. Transcriptome and chromatin accessibility in CD14+ cells were analyzed by RNA-seq and ATAC-seq. Epigenetic reprogramming in CD14+ cells of the cyclic AMP/CREB pathway correlated with vaccine efficacy. The efficacy of V1-delted DNA/ALVAC/gp120/alum vaccine, based on V2-specific antibodies mediating apoptosis of infected cells (V2-ADCC), is complemented by efferocytosis, a cyclic AMP (cAMP)-dependent antiphlogistic engulfment of apoptotic cells by CD14+ monocytes. Our data support the protective role for CREB1 expression in monocytes and posit that efferocytosis, through the prompt and effective removal of apoptotic infected cells, contributes to vaccine efficacy by decreasing inflammation and maintaining tissue homeostasis.

Expression data from intermediate monocytes from healthy donors and autoimmune uveitis patients

Project description:Human peripheral monocytes have been categorized into three subsets based on differential expression levels of CD14 and CD16. However, the factors that influence the distribution of monocyte subsets and the roles which each subset plays in autoimmunity are not well studied. To compare the gene expression profiling 1) on intermediate monocytes CD14++CD16+ monocytes between healthy donors and autoimmune uveitis patients and 2) among 3 monocyte subsets in health donors, here we purified circulating intermediate CD14++CD16+ monocytes from 5 patients with autoimmune uveitis (labeled as P1-5) and 4 healthy donors (labeled as HD1-4) by flow cytometry and isolated total RNA to proceed microarray assay. In addition, we also purified CD14+CD16++ (non-classical monocytes) and CD14++CD16- (classical monocytes) from 4 healthy donors to do microarray. We demonstrate that CD14++CD16+ monocytes from patients and healthy control donors share a similar gene expression profile. The CD14+CD16++ cells (non-classical monocytes) display the most distinctive gene expression profiling when compared to intermediate CD14++CD16+ monocytes and classical CD14++CD16- monocytes.

SuperSAGE evidence for CD14++CD16+ monocytes as a third monocyte subset

Project description:Monocytes are a heterogeneous cell population with subset-specific functions and phenotypes. The differential expression of CD14 and CD16 distinguishes classical CD14++CD16-, intermediate CD14++CD16+ and non-classical CD14+CD16++ monocytes. However, CD14++CD16+ monocytes remain the most poorly characterized subset so far. Therefore we analyzed the transcriptomes of the three monocyte subsets using SuperSAGE in combination with high-throughput sequencing. Analysis of 5,487,603 tags revealed unique identifiers of CD14++CD16+ monocytes, delineating these cells from the two other monocyte subsets. CD14++CD16+ monocytes were linked to antigen processing and presentation (e.g. CD74, HLA-DR, IFI30, CTSB), to inflammation and monocyte activation (e.g. TGFB1, AIF1, PTPN6), and to angiogenesis (e.g. TIE2, CD105). Therefore we provide genetic evidence for a distinct role of CD14++CD16+ monocytes in human immunity. Human monocyte subsets (CD14++CD16-, CD14++CD16+, CD14+CD16++) were isolated from 12 healthy volunteers based on MACS technology. Total RNA from monocyte subsets was isolated and same aliquots from each donor and monocyte subset were matched for SuperSAGE. Three SuperSAGE libraries (CD14++CD16-, CD14++CD16+ and CD14+CD16++) were generated.
