• CLL Genome

  The Chronic Lymphocytic Leukemia (CLL) Genome Project aims to identify genetic alterations involved in the development and progression of the CLL, which are still unknown, with the objective of generating a comprehensive catalogue of genetic alterations in 500 independent tumours. The CLL Genome Project, as a contributing member of the International Cancer Genome Consortium (ICGC), has the purposes of creating diagnostic tools, discovering therapeutic targets and developing new strategies that will allow a customized therapy for CLL in order to make it more precise and effective. This study consists of two datasets. EGAD00001000023 described in the Nature paper (2011), Whole-genome sequencing identifies recurrent mutations in chronic lymphocytic leukaemia, and the dataset EGA00001000044 & & EGAD00001000083 described in the Nature (2011) paper, Exome sequencing identifies recurrent mutations of the splicing factor SF3B1 gene in chronic lymphocytic leukemia.Additional data generated within the ICGC-CLL genome project can be found in studies EGAS00001000374 and EGAS00001001306

• Genomic and Transcriptomic Profiling of Colorectal Cancer in Swedish Patients

  My descriptionThis study investigates the genomic and transcriptomic landscape of colorectal cancer (CRC) in Swedish patients to identify molecular biomarkers associated with disease progression, treatment response, and survival outcomes. A total of 350 patients diagnosed with CRC between 2018 and 2023 were recruited from three Swedish hospitals: Lund University Hospital, Karolinska University Hospital, and Sahlgrenska University Hospital. Matched tumor tissue and blood samples were collected from all participants after obtaining informed consent. Whole-genome sequencing (WGS) was performed on blood-derived DNA to identify germline variants, while RNA-seq analysis of tumor tissues provided transcriptomic profiles. In addition, targeted panel sequencing was carried out for selected cancer-related genes to confirm findings from the WGS data.

• Whole-Genome and Transcriptomic Data from Colorectal Cancer Patients and Matched Healthy Controls in Sweden

  This dataset contains whole-genome sequencing (WGS) and RNA-seq data generated from tumor samples, matched blood samples, and healthy control samples collected from 350 Swedish individuals between 2019 and 2023. Tumor biopsies were obtained from colorectal cancer (CRC) patients, while control samples were collected from age- and sex-matched healthy volunteers with no history of CRC. For tumor samples, paired-end RNA-seq was performed to capture gene expression profiles, and WGS was carried out on DNA extracted from both tumor tissue and matched blood samples to identify somatic and germline variants. For controls, WGS was performed on peripheral blood DNA to provide baseline genomic profiles for comparison. The resulting dataset includes: RNA-seq files in FASTQ format (~2.8 TB total) WGS files in CRAM format (~4.2 TB total) Variant calls in VCF format (~150 GB) Clinical and sample metadata in CSV format Data are stored in FEGA Sweden under controlled access. Access requests will be reviewed by the Lund University RDO as the data controller. Ethical approval was obtained from the Swedish Ethical Review Authority (Dnr: 2023-01234).

• DNA Methylation and Microbiome Profiles from Colorectal Cancer Patients and Healthy Controls

  This dataset contains DNA methylation data and gut microbiome profiles derived from tumor biopsies, matched blood samples, and stool samples collected from 200 Swedish participants (150 colorectal cancer patients and 50 healthy controls) between 2020 and 2023. For DNA methylation profiling, genomic DNA was extracted from tumor tissues and blood samples using the Qiagen AllPrep DNA/RNA Kit and analyzed with the Illumina Infinium MethylationEPIC BeadChip. This approach captures more than 850,000 methylation sites across the genome. In parallel, stool samples were collected prior to treatment, and microbial DNA was extracted using the Qiagen QIAamp Fast DNA Stool Kit. 16S rRNA gene sequencing was performed on the Illumina MiSeq platform to characterize the gut microbiome composition in patients and controls. The resulting dataset includes: Methylation array data in IDAT format (~120 GB total) Normalized methylation matrices in CSV format (~15 GB) 16S rRNA microbiome data in FASTQ format (~250 GB total) Microbiome abundance tables in TSV format (~2 GB) All data are stored in FEGA Sweden under controlled access, and access requests will be reviewed by the Lund University RDO as the data controller. Ethical approval was obtained from the Swedish Ethical Review Authority (Dnr: 2023-04567).

• Personalized Onco-Genomic Project for pediatric and adolescent patients in British Columbia

  This is an extension of the BC Cancer Agency's Personalized Onco-Genomics (POG) project to children and adolescents treated at BC Children's Hospital. The project provides access to whole genome and transcriptome sequencing, and integrated bioinformatics analyses, of relapsed, refractory or poor prognosis cancers with an aim to identify actionable variants that can inform clinical decision making.

• Integrative genomic analyses reveal androgen-driven somatic alteration landscape in early-onset prostate cancer

  Early-onset prostate cancer (EO-PCA) represents the earliest clinical manifestation of prostate cancer. To compare the genomic alteration landscapes of EO-PCA with "classical" (elderly-onset) PCA, we performed deep sequencing-based genomics analyses in eleven tumors diagnosed at young age, and pursued comparative assessments with seven elderly-onset PCA genomes. Remarkable age-related differences in structural rearrangement (SR) formation became evident, suggesting distinct disease pathomechanisms. Whereas EO-PCAs harbored a prevalence of balanced SRs, with a specific abundance of androgen-regulated ETS gene fusions including TMPRSS2:ERG, elderly-onset PCAs displayed primarily non-androgen-associated SRs. Data from a validation cohort of >10,000 patients showed age-dependent androgen receptor levels and a prevalence of SRs affecting androgen-regulated genes, further substantiating the activity of a characteristic "androgen-type" pathomechanism in EO-PCA.

• Integrative sequencing reveals alterations in untreated and castration resistant prostate cancer

  We report the integrative sequencing of genomic, transcriptomic and DNA methylation changes in 28 untreated (PC) and 13 castration resistant prostate cancers (CRPC). AR, TGF-β and WNT signaling pathways were altered in CRPCs. We identified two new fusion genes, TMPRSS2-SKIL and DOT1L-HES6. Fusion analysis in an independent cohort validated SKIL as a recurrent 3’ fusion partner and oncogene in prostate cancer. The HES6 fusion was found in an AR-negative CRPC, and HES6 overexpression in vitro led to androgen independent growth. A distinct DNA methylation signature was found for CRPC. Transcriptome assembly uncovered 128 previously unannotated prostate cancer associated transcripts, including the ERG regulated transcript TPCAT-10-36067 whose knockdown had a dramatic effect on the growth, invasiveness, and rate of apoptosis of prostate cancer cells.
