Aberrant epigenetic regulation in clear cell sarcoma of the kidney (CCSK)

ABSTRACT: Methylation array analyses of 30 CCSKs in comparison with 18 Wilms tumours and normal non-malignant kidneys (2 foetal kidneys and 6 adult kidneys) revealed CCSK tumour DNA to be globally hypermethylated. Four CCSKs, two WTs, two foetal kidneys and 2 adult kidneys were analysed as technical duplicates on different arrays.

CCSK

Project description:Clear cell sarcoma of the kidney (CCSK), the second most common renal tumor in children, poses significant diagnostic challenges. No diagnostic positive markers are available, and the pathogenesis of CCSK remains an enigma. To address these challenges, the gene expression patterns of fourteen CCSKs were compared to fifteen Wilms tumors (WT) and three fetal kidney samples using oligonucleotide arrays. Keywords: other

Lin28 sustains early renal progenitors and induces Wilms tumor

Project description:Wilms Tumor, the most common pediatric kidney cancer, evolves from the failure of terminal differentiation of the embryonic kidney. Here we show that over-expression of the heterochronic regulator Lin28 during kidney development in mice markedly expands nephrogenic progenitors by blocking their final wave of differentiation, ultimately resulting in pathology highly reminiscent of Wilms tumor. Gene expression analysis was performed on a total of 8 kidneys samples, including 4 tumors samples from Lin28 transgenic mice and 4 control kidneys

The epithelial splicing regulator ESRP2 is epigenetically repressed by DNA hypermethylation in Wilms tumour and acts as a tumour suppressor

Project description:Wilms tumour (WT), a childhood kidney cancer with embryonal origins, has been extensively characterised for genetic and epigenetic alterations, but a proportion of WTs still lack identifiable abnormalities. To uncover DNA methylation changes critical for WT pathogenesis, we compared the epigenome of fetal kidney with two WT cell lines, using methyl-CpG immunoprecipitation. We filtered our results to remove common cancer-associated epigenetic changes, and to enrich for genes involved in early kidney development. This identified four candidate genes that were hypermethylated in WT cell lines compared to fetal kidney, of which ESRP2 (epithelial splicing regulatory protein 2), was the most promising gene for further study. ESRP2 was commonly repressed by DNA methylation early in WT development (in nephrogenic rests) and could be reactivated by DNA methyltransferase inhibition in WT cell lines. When ESRP2 was expressed in WT cell lines, it acted as an inhibitor of cellular proliferation in vitro and in vivo it suppressed tumour growth of orthotopic xenografts in nude mice. RNA-seq of the ESRP2-expressing WT cell lines identified several novel splicing targets, in addition to well-characterised targets of ESRP2. One of these targets, LEF1, is a component of the Wnt signalling pathway that is essential for kidney development and commonly disrupted in WT. We propose a model in which the Wnt pathway can be disrupted in early kidney development to generate WT, either by genetic abnormalities such as WT1 mutations, or by epigenetic defects, such as ESRP2 methylation. The microarray data in this deposition identified ESRP2 as a commonly hypermethylated gene in Wilms tumour.

Foetal and adult HSPCs - Comprehensive Proteomic Characterization of Ontogenic Changes in Hematopoietic Stem and Progenitor Cells

Project description:Haematopoietic stem and progenitor cells (HSPCs) in the foetus and adult possess distinct molecular landscapes that regulate cell fate and change their susceptibility to initiation and progression of haematopoietic malignancies. The proteomic programs that govern these differences remain elusive. In this study, we have utilized a mass spectrometry-based quantitative proteomics approach to comprehensively describe and compare the proteome of foetal and adult HSPCs. We found that the proteome of foetal HSPCs is relatively simple, characterized by proteins involved in cell cycle and cell proliferation, while their adult counterparts are defined by a larger set of proteins that are involved in more diverse cellular processes. These adult characteristics include an arsenal of proteins important for viral and bacterial defence, as well as protection against ROS-induced protein oxidation. Our further analyses of Type I interferon signalling shows that foetal HSPCs are sensitive to Interferon a (IFNa), which impairs their production of mature lymphoid cells, whereas stimulation with IFNa to the pregnant mother enhances the production of early progenitors from foetal HSCs. Our results provide new and important insights into the molecular landscape of foetal and adult haematopoiesis that advance our understanding of normal and malignant haematopoiesis during foetal and adult life.

A single-cell comparison of adult and foetal human epicardium defines the age-associated changes in epicardial activity

Project description:Re-activating quiescent adult epicardium represents a potential therapeutic approach for human cardiac regeneration. However, the exact molecular differences between inactive adult and active foetal epicardium are not known. Here, we combined foetal and adult human hearts for the first time using single-cell and single-nuclei RNA sequencing, and compared epicardial cells from both stages. We found a migratory fibroblast-like epicardial population only in the foetal heart and foetal epicardium expressed angiogenic gene programs, while the adult epicardium was solely mesothelial and immune-responsive. Furthermore, we predicted that adult hearts may still receive foetal epicardial paracrine communication, including WNT-signalling with endocardium, reinforcing the validity of regenerative strategies that administer or reactivate epicardial cells in situ. Finally, we explained graft efficacy of our human embryonic stem-cell derived epicardium model, by noting its similarity to human foetal epicardium. Overall, our study defines epicardial programs of regenerative angiogenesis absent in adult hearts, contextualises animal studies, and defines epicardial states required for effective human heart regeneration.
