• RNA-seq analysis of megakaryocytes and granulocytes in Quebec platelet disorder

  Quebec Platelet disorder (QPD) is a unique bleeding disorder that markedly increases urokinase plasminogen activator (uPA) in megakaryocytes and platelets but not in plasma or urine. The cause is tandem duplication of a 77 kb region of chromosome 10 containing PLAU and C10orf55. Blood cells and cultured megakaryocytes from donors (7 QPD, 10 control subjects) were prepared for total and allele-specific, quantitative reverse transcription polymerase chain reaction, immunoassays, Western blots and RNA-seq. Transcriptomes for cultured megakaryocytes and peripheral blood granulocytes from 4 control and 3 QPD individuals were analyzed using mRNA-seq.

• Novel Epigenetic Markers for Toxicity after Intraoperative and Conventional Radiotherapy for Breast Cancer

  Ionizing radiation is a common treatment option for cancer but its use is limited by the unpredictable and highly heterogeneous onset of late side effects, especially radiation-induced fibrosis. Clinically applicable biomarkers and effective treatments for radiation fibrosis are currently unavailable. In order to identify novel markers we ran a genome-wide DNA methylation screen in primary dermal fibroblasts obtained from breast cancer patients before intraoperative radiotherapy. Cells from patients developing fibrosis within a three-year follow up were compared to those without fibrosis (12 individuals per group). Illumina Infinium HumanMethylation450 BeadChip Technology was used.

• Non-invasive prenatal diagnosis by genome-wide haplotyping of maternal cell-free plasma DNA

  Whereas non-invasive prenatal testing for aneuploidies (NIPT-A) is widely implemented, non-invasive prenatal testing for monogenic diseases (NIPT-M) is lagging. By capturing and targeted sequencing of 250000 polymorphic SNP loci from maternal plasma circulating cell-free DNA (cfDNA) and DNA from relatives, the fetal haplotype and chromosomal copy numbers are deduced. In all families tested, the cfDNA derived haplotypes are on average 97% concordant with the neonatal and embryo haplotype. This generic non-invasive prenatal diagnostic approach allows cost efficient scrutinizing the fetal genome for the presence of any inherited monogenic disease or trait.

• WXS of 147 lung cancer patients treated with immunotherapy

  We first attempted to predict MHC-binding neoantigens at high accuracy with convolutional neural networks. This prediction model outperformed previous methods in > 70% of test cases. Importantly, our method remarkably increased the predictive value of neoantigen load especially in combination with known resistance parameters. We then developed a classifier that can predict resistance from point mutations that are deleterious to protein function. Notably, genes involved in the adaptive immune response, cytokine signaling,and EGFR signaling held high explanatory power. Furthermore, when integrated with our neoantigen profiling, these anti-immunogenic mutations revealed significantly higher predictive power than known resistance factors.

• Whole genome and whole transcriptome sequencing of patients diagnosed with angiosarcoma.

  Angiosarcomas are rare, clinically-aggressive tumors with a predilection for the elderly and immunosuppressed, which has incited suspicion of an oncogenic virus. We studied the metagenomic landscape of angiosarcomas and identified reads mapping to human herpesvirus-7 (HHV-7). Overall, HHV-7 was present in two-thirds of angiosarcomas, particularly in cases with low tumor mutation burden and lacking signatures of ultraviolet-induced DNA damage. Transcriptomic profiling revealed the enrichment of tumor inflammation signatures in HHV7-positive angiosarcomas. In conclusion, we identified a distinct “inflammatory” subtype of angiosarcoma associated with HHV-7.

• Transcriptomic analysis of the Phase 3 COMPARZ clinical trial

  Metastasis remains the main reason for renal cell carcinoma (RCC)-associated mortality. Tyrosine kinase inhibitors (TKI) impart clinical benefit for most RCC patients but the determinants of response are poorly understood. We report an integrated genomic and transcriptomic analysis of metastatic clear cell RCC (ccRCC) patients treated with TKI therapy and identify predictors of response. Patients in the COMPARZ phase III trial received first-line sunitinib or pazopanib with comparable efficacy. Microarray-based transcriptomic analyses with results from Next-gen genomic analyses of targeted genes revealed distinct molecular subgroups associated with response and survival.

• Single cell T cell Landscape and T Cell Receptor Repertoire Profiling of AML in Context of PD-1 Blockade Therapy

  Eight pretreatment and 14 posttreatment bone marrow (BM) aspirates from 8 patients with R/R AML treated with azacitidine and nivolumab along with 2 control BM from healthy donors were profiled with scRNA sequencing with matching scTCR -, scBCR - and scATAC sequencing. Additionally, the targeted DNA sequencing in at least 1 time point per patient (total evaluated 17/22 samples, two samples were performed using CLIA-certified molecular diagnostic assay and data is not available) was performed. The Fastq files and/or bam files are available in this dataset.

• The exomic landscape of t(14,18) negative diffuse follicular lymphoma with 1p36 deletion

  t(14,18) negative diffuse follicular lymphoma with 1p36 deletion is a well characterized variant of follicular lymphoma with typical clinical, morphological, immunophenotypical and genetic features. The genetic landscape of this variant is however largely unknown. We performed exome sequencing of six well characterised cases and detected 1642 single nucleotide variations and 641 insertions-deletions not reported in common databases (dbSNP and 1000G). We report several recurrent mutations, among which CREBBP, STAT6, KMT2D, HEATR6, LAMA5 and VPS13B are the most prevalent. Pathway annotation using GSEA showed an enrichment in mutated genes belonging to the MAPK pathway.

• Chracterising_cellur_pathways_underlying_CD3_CD28_activation_of_human_CD4__cells

  We devised an approach to disentangle the TCR and CD28 pathways upon stimulation in naive and memory primary human CD4+ T cells (Tcons) in response to defined stimulatory signals. Isolated memory and naïve T cells were activated using anti-CD3, anti-CD28 or both in combination. As a control we cultured cells in the same conditions but without the stimuli. We carried Chipmentation using the H3K27ac antibody on 200,000 cross-linked cells. 1) This data is part of a pre-publication release.

• Natural variation of circulating RNAs in human serum

  Non-coding RNA (ncRNA) molecules have fundamental roles in cells and many are also stable in body fluids as extracellular RNAs. In these studies, we used RNA sequencing (RNA-seq) to investigate the profile of small non-coding RNA (sncRNA) in human serum. We analyzed more than 10 billion Illumina reads from more than 500 serum samples, included in the Norwegian population-based Janus Serum Bank (JSB). Our results suggest that many circulating RNAs in serum can be potential biomarkers and they are associated with different traits including age, sex, smoking, body size etc.
