• RNA sequencing data and whole exome sequencing data of genetically modified IDH1 wildtype and mutant chondrosarcoma cell lines

  This dataset contains total RNA sequencing (polyA enriched) data of early and late passages of n=5 vector-based CH2879 empty vector and IDH1mut cell lines. Total RNA sequencing (polyA enriched) using 150bp paired-end reads was performed in triplicate using the NEBNext Ultra II Directional RNA Library Prep Kit (New England Biolabs) on the NovaSeq6000 platform (Illumina). Additionally, this dataset contains whole exome sequencing data of n=15 parental, mock, and CRISPR-edited IDH1mut and IDH1wt CH2879 and JJ012 cell lines. Whole exome sequencing using 150bp paired-end reads with a minimum coverage of 100x was performed in single using the SureSelect Human All Exon V8 library (Agilent Technologies) on the NovaSeq X platform (Illumina).

• Differential Wnt/β-Catenin Signaling Activities Shape Distinct Tumor Cell Phenotypes

  By profiling patient-derived hepatoblastoma organoids via single-cell transcriptomics and chromatin dynamics, we identify subtype-specific transcriptional and epigenetic profiles. Using CUT&RUN, we show that β-catenin engages distinct genomic regions, which is dictated by differential association with TCF/LEF family transcription factors. TCF7L2 binds to a motif, distinct from the classical Wnt consensus sequence, which is found in the promoter of hepatic target genes.

• Full AfricanNeo ModernDNA Study

  With the largest genomic dataset to date of Bantu-speaking populations, including newly generated data of modern-day and ancient DNA from previously unsampled regions in Africa, we shed fresh light on the expansion of peoples speaking Bantu languages that started ~4000 years ago in western Africa. We have genotyped 1,763 participants, including 1,487 Bantu speakers from 143 populations across 14 African countries. Our comprehensive genetic analysis of the expansion of people speaking Bantu languages reveals a complex history of serial founder events, variable levels of contact with local groups, and spread-over-spread events.

• Molecular Landscape of Hypertrophic Cardiomyopathy Across Disease Stages and Genotypes

  Hypertrophic Cardiomyopathy (HCM) is marked by asymmetric cardiac wall thickening, enhanced contractility, diastolic dysfunction, and fibrosis. Pathogenic sarcomere gene variants cause HCM, but comparable abnormalities occur in patients with unexplained disease albeit with fewer adverse events. We applied single-nucleus RNA sequencing to investigate how genetic and unexplained HCM affect early disease mechanisms and to contrast HCM with dilated cardiomyopathy (DCM). This EGA dataset contains HCM and control data. DCM and additional control snRNA-seq data, integrated in this study, are available under the EGA dataset accession number: EGAD00001009292.

• Long-read single-cell genome, transcriptome and open chromatin profiling links genotype to phenotypes

  Current single-cell multiomics methods typically provide limited genomic information, constraining genotype-phenotype studies. To address this gap, we developed SPLONGGET (Single-cell Profiling of LONG-read Genome, Epigenome, and Transcriptome), which integrates 10X Genomics barcoding with Oxford Nanopore sequencing to simultaneously profile genome, chromatin accessibility, and full-length transcriptomes in thousands of single cells. By retaining all tagmentation fragments during library preparation, SPLONGGET delivers whole-genome coverage, supports target enrichment for effective single-cell genotyping, and remains backwards compatible with existing short-read workflows. We apply SPLONGGET to longitudinal samples from a case of pediatric B-cell acute lymphoblastic leukemia (B-ALL) to reveal clonal dynamics during therapy and the phenotypic effects of somatic variation, providing valuable insights into disease progression and relapse. In conclusion, SPLONGGET enables integrated high-throughput analysis of genetic variation and molecular phenotypes using off-the-shelf kits, offering a timely and powerful tool to study genetically heterogeneous samples, such as tumours but also ageing normal tissues.

• Raw fastq files (not trimmed) from RNAseq sequencing

  Samples from infants diagnosed with KMT2A-r B-ALL confirmed by comprehensive immunophenotypic and molecular/cytogenetic features. Mononuclear cells containing >87% blasts were isolated by density gradient centrifugation. Immunophenotyping was performed using the monoclonal antibodies CD45-FITC, CD19-APC, and NG2-PE. NG2POS (NG2 positive) and NG2NEG (NG2 Negative) B-ALL blasts (CD45dimCD19+) were sorted by fluorescence-activated cell sorting (FACS) using a FACS-Aria Fusion cell sorter (BD Biosciences).

• Proteomics of human cancer-associated T cells identifies regulators of T cell functionality

  CD8⁺ T cells in solid tumors progressively lose anti-tumor activity, yet the cell-intrinsic mechanisms driving this loss of function remain incompletely defined. Here, we performed matched proteomic and transcriptomic profiling of dysfunctional and bystander CD8⁺ tumor-infiltrating T cells isolated from primary tumors of treatment-naïve non-small cell lung cancer patients. Proteomic analysis revealed widespread discordance with mRNA expression, with 8% of differentially expressed proteins detected exclusively at the protein level. Genetic perturbation of such differentially expressed proteins identified the chromatin remodeler CHD4 and fatty acid synthase (FASN) as cell-intrinsic regulators of T cell function. CHD4 deletion promoted effector differentiation and enhanced cytokine production, whereas FASN deletion preserved mitochondrial fitness and sustained T cell functionality under chronic T cell receptor stimulation. Together, these findings demonstrate that proteomic profiling uncovers regulators of T cell functionality that are not apparent from transcriptomic analyses alone, highlighting an additional layer of regulatory control.

• Frequency and prognostic significance of genetic abnormalities in a subgroup of intermediate risk neuroblastoma patients: A SIOPEN study

  Intermediate risk neuroblastoma includes a rare subgroup of patients over the age of 18 months at diagnosis with unresectable, localised tumours with unfavourable histology without MYCN amplification. This group is treated differently around the world with some patients receiving upfront myeloablative therapy (MAT) in addition to standard treatment with chemotherapy, surgery, radiotherapy and 13 cis retinoic acid, but the overall 5-year patient survival with or without MAT is similar (75%). This study aimed to understand the neuroblastoma biology of this rare patient subgroup.
