• COVID-19 Multiomics Atlas

  We provide a single-nuclei RNA-sequencing (snRNA-seq) dataset derived from four COVID-19 patients, generated using the 10x Chromium Next GEM Single Cell v3.1 kit. For our study, these were integrated with snRNA-seq data with 12 publicly available sc/snRNA-seq datasets, comprising organ donor lung samples (n=89) and COVID-19 lung tissue samples (n=51). Additionally, we provide a spatial transcriptomic dataset characterizing different histopathological stages of diffuse alveolar damage, across a cohort of 33 COVID-19 patients. This was generated using the Nanostring Whole Transcriptome Assay (WTA) with regions of interest (ROIs) sized 400 µm² each. This integrated multi-omics analysis of snRNA-seq, histology, and spatial transcriptomics data, is available for exploration and download via our web portal: https://covid19-multiomicatlas.cellgeni.sanger.ac.uk/.

• Evolutionary trajectories and clonal migration underlying tumor progression and lymph node metastasis in resectable lung cancer

  In this prospective study, targeted deep sequencing was performed on a total of 160 primary tumors (474 regions) and 112 lymph nodes from 125 patients with stage I-III lung cancer (LuCaTH). Progressive evolution at clonal divergence scale was observed while specific driver events were positively selected for clonal sweeps during tumor development. Between-region genetic divergence (BRGD) of tumors were assessed and positively correlated with tumor differentiation. A machine learning algorithm was employed to evaluate clinicopathological and molecular parameters of primary tumors underlying lymph node metastasis. By analyzing clonal lineages and metastatic trajectories across multiple nodal stations, we unraveled a common sequential LNM seeding pattern but with divergent modes of clonal spread.

• Single cell transcriptomes of of primary tumors and normal endometrial derived organoids treated with DBZ

  Endometrial carcinoma, the most common gynecologic cancer, develops from endometrial epithelium which is composed of secretory and ciliated cells. Pathologic classification is unreliable and there is a need for prognostic tools. We used single cell sequencing to study organoid model systems derived from normal endometrial endometrium to discover novel markers specific for endometrial ciliated or secretory cells. We performed single cell sequencing on endometrial and ovarian tumours, and on organoids both treated with DBZ and normal and found both secretory-like and ciliated-like tumour cells.

• Colorectal cancer organoid-stroma biobank cohort

  In colorectal cancers (CRC) the tumor microenvironment plays a key role for prognosis and therapy efficacy. Patient-derived tumor organoids (PDTOs) show enormous potential for preclinical testing, however, purely epithelial cultures features including the ‘consensus molecular subtypes’ (CMS) are largely eradicated. To better reflect the cell type heterogeneity, we established the CRC organoid-stroma biobank of matched PDTOs and cancer-associated fibroblasts (CAFs) from 30 patients. Whole exome sequencing and transcriptome analysis in various in vitro and in vivo contexts was performed to study the influence of the TME on the CRC phenotype.

• Single-cell RNA sequencing of human kidney transplant nephrectomies with chronic rejection or non-alloimmune graft injury

  This dataset contains raw single-cell RNA sequencing (scRNA-seq) data for five new kidney allograft nephrectomy samples used to construct the described in the following study: https://www.biorxiv.org/content/10.1101/2022.10.28.514222v2.full. The full description of processing is described in the manuscript. Briefly, samples were digested into a single cell suspension and run according to the 10X Genomics Chromium 5’ single cell kit (v2). Sequencing was performed using an Illumina Novaseq instrument. Samples were designated as TXN2 (EGAN00002519570, mycotic pseudoaneurysm, control dataset), TXN3 (EGAN00002235628, renal vein thrombus, control dataset), TXN5 (EGAN00002519573, chronic transplant rejection), TXN6 (EGAN00002519572, chronic pyelonephritis and renal artery stenosis, non-alloimmune graft injury dataset), TXN7 (EGAN00002519576, recurrent focal segmental glomerulosclerosis, non-alloimmune graft injury dataset).

• Single-cell Transcriptomic and TCR Repertoire Profiling of DENV-specific CD8+ T Cells Across Dengue Disease Severities

  This dataset contains single-cell RNA sequencing (Smart-seq2) and paired TCR repertoire data of sorted dengue virus (DENV)-specific CD8⁺ T cells from individuals with differing clinical outcomes: asymptomatic dengue (AD), dengue fever (DF), and dengue hemorrhagic fever (DHF). Samples were obtained from HLA-A11⁺ and HLA-A24⁺ individuals during acute and convalescent phases, with antigen-specific CD8⁺ T cells isolated using HLA tetramers loaded with immunodominant DENV epitopes. The study identifies phenotypically distinct T cell subsets associated with disease severity, TCR avidity, and antigen reactivity to current or prior DENV serotypes. The dataset supports the understanding of CD8⁺ T cell heterogeneity, TCR features, and potential mechanisms of CD8⁺ T cell-mediated protection versus immunopathogenesis in dengue infection.

• sWGS of OV04 patient samples for ACN rascal study

  This dataset contains 142 .bam files of shallow WGS data (~0.1X) from OV04 patient samples. Sequencing reads were aligned to the 1000 Genomes Project GRCh37-derived reference genome using the BWA aligner (v.0.07.17; CRUK-CI alignment pipeline).

• Gene expression by RNAseq in bronchial biopsies of asthmatics, asthma in remission and healthy subjects

  The study focus was differential expression in bronchial biopsies between persistent asthma, asthma in remission and healthy controls using RNAseq. There were 184 samples that passed QC. RNA samples were processed using the TruSeq Stranded Total RNA Sample Preparation Kit (Illumina, San Diego, CA), using an automated procedure in a Caliper Sciclone NGS Workstation (PerkinElmer, Waltham, MA). In this procedure, all cytoplasmic and mitochondria rRNA was removed (RiboZero Gold kit). The obtained cDNA fragment libraries were loaded in pools of multiple samples unto an Illumina HiSeq2500 sequencer using default parameters for paired-end sequencing (2 × 100 bp). Data are available as 221 pairs of FASTQ-files. Note that several samples are associated with multiple sequence runs.

• Whole exome sequencing data of tumor/normal pairs for the study "TGF-β attenuates tumour response to PD-L1 blockade by contributing to exclusion of T cells"

  Tumor DNA was extracted from formalin-fixed and paraffin embedded tumors of a large cohort of bladder cancer patients before treatment with anti-PD-L1. Normal DNA was extracted from matched PBMCs. Whole exome sequencing was performed. This is a subset of patients for which RNA sequencing is also provided (with more detailed phenotypic information).

• Inherited MUTYH mutations cause elevated somatic mutation rates and distinctive mutational signatures in normal human cells

  Cellular DNA damage caused by reactive oxygen species is repaired by the base excision repair (BER) pathway which includes the DNA glycosylase MUTYH. Inherited biallelic MUTYH mutations cause predisposition to colorectal adenomas and carcinoma. However, the mechanistic progression from germline MUTYH mutations to MUTYH-Associated Polyposis (MAP) is incompletely understood. Here, we sequenced normal cell DNAs from 10 individuals with MAP and study the somatic mutation burden and mutational signatures.
