• Characterization of a New Case of XMLV (Bxv1) Contamination in the Human Cell Line Hep2 (Clone 2B) Using High-Throughput DNA- and RNA-Seq

  We have sequenced DNA and RNA from the Hep2 (clone 2B) cell line (Sigma-Aldrich catalog number: 85011412-1VL) using short read Illumina sequencing. We show that this cell line is indistinguishable from the HeLa cell line (as mentioned on the Sigma-Aldrich website) by mapping integrations of the human papillomavirus 18. We also show that the cell line is contaminated by the Bxv1 xenotropic murine leukemia virus. This contamination has to be taken into account when using the cell line in future experiments.

• Spatial Transcriptomic Analysis (Xenium in situ) of Large Cell Neuroendocrine Carcinoma

  Lung LCNEC (Large Cell Neuroendocrine Carcinoma) has a poor prognosis, and no effective treatment has yet been established. We have discovered that LCNEC exhibits highly heterogeneous distribution of proteins such as neuroendocrine markers and YAP1 within the tumor. We hypothesize that this heterogeneity may be responsible for the variability in chemotherapy effectiveness and treatment resistance among LCNEC patients. Therefore, by using Xenium to analyze gene expression in greater detail along with tumor morphology, we aim to identify new characteristics of LCNEC and explore potential treatment strategies.

• Bone morphogenetic protein-9 controls pulmonary vascular growth and remodeling

  Pulmonary arterial hypertension (PAH) and hereditary hemorrhagic telangiectasia (HHT) are two distinct vascular diseases linked to impaired signaling through bone morphogenetic protein (BMP) receptor complexes in endothelial cells. Although BMP-9 plays a central role in activating this pathway by binding to ALK1 and BMPR-­II, its precise function in the pulmonary microvasculature has remained unclear. In this study, we uncover a previously unrecognized role for BMP-9 in regulating pulmonary vascular architecture and homeostasis. Our findings demonstrate that BMP-9 signaling intersects with VEGF pathways and contributes to the delicate balance between vascular growth and remodeling in the lungs. We also show that disruption of this pathway can shift vascular responses toward an HHT-­like state, potentially altering disease susceptibility. These insights offer a unique perspective on how BMP-9 and ALK1 shape pulmonary vascular biology and suggest that targeting this axis could inform future strategies for treating complex vascular diseases such as PAH.

• Comprehensive peripheral blood immunoprofiling reveals five immunotypes with immunotherapy response characteristics in cancer patients

  The lack of comprehensive diagnostics and consensus analytical models for evaluating the status of a patient’s immune system has hindered a wider adoption of immunoprofiling for treatment monitoring and response prediction in cancer patients. To address this unmet need, we developed an immunoprofiling platform that uses multiparameter flow cytometry and RNA-seq to characterize immune cell heterogeneity in the peripheral blood of healthy donors and patients with advanced cancers. Using unsupervised clustering, we identified five immunotypes with unique distributions of different cell types, and gene expression profiles.

• IgM heavy chain V(D)J library sequencing using varied PCR parameters

  When amplifying the rearranged V(D)J genes encoding antigen receptors during adaptive immune receptor repertoire sequencing (AIRR-seq), each cycle of the PCR can produce spurious “chimeric” hybrids of two or more different template sequences. To test the effects of PCR protocol variation on chimera formation in AIRR-seq, we produced IgM heavy chain V(D)J repertoire libraries under 8 conditions, varying the number of PCR cycles, indexing PCR template, input RNA, and extension time. Three donors were sequenced using all 8 conditions.

• RNA seq data of 2 lung cancer samples prepared using 2 different RNA-seq library preparation protocols

  Raw data used for generation of the results in the Vardetector manuscript – “.bam” files of RNA-seq data of tumor samples of 2 patients prepared with 2 different library preparation protocols (exome-capture and ribodepletion –> 4 “.bam” files in total). The submission also contains the somatic mutations “.vcf” files (4 in total, however 2 unique). Moreover, also an output of the Vardetector module (“.csv” file with the number of reads above the mutations of interest) is present in the submission (4 “.csv” files in total).

• Clonal evolution of metastatic colorectal cancer under anticancer therapies

  To investigate the clonal evolution of metastatic CRC at the single-cell level, we performed WGS in 58 clonal organoids and 18 fresh-frozen (FT) bulk-tissue samples from surgically resected primary and metastatic tumors before and after anticancer therapies in 6 patients. This approach enabled detailed phylogenetic reconstruction of individual clones. We discovered the timing and burden of treatment-related mutations as well as the heterogeneous evolution in driver mutations and genomic rearrangements in late-stage clonal evolution under anticancer therapies in metastatic CRC.

• Searching for rare/low frequency variants in rheumatoid arthritis by exome sequencing

  Rheumatoid arthritis (RA) is a multifactorial and systemic autoimmune disease and characterized by synovial inflammation and hyperplasia, autoantibody production, cartilage and bone destruction and systemic features including cardiovascular, pulmonary, psychological and skeletal disorders. Although the causality of RA is not completely understood, genetic factors contribute to the onset. About 60% of the RA risk is genetic. To identify causative- or susceptible- rare/low-frequency variants in RA, exome sequencing of 39 patients with RA was conducted. We also conducted genotyping of pooled healthy men and women exome-sequencing data.

• Integrated multi-omics analysis of pediatric hepatoblastoma

  Hepatoblastoma (HBL) is the most common malignant liver tumor in childhood and is clinically heterogeneous. In spite of its heterogeneity, the molecular basis responsible for the difference between low-risk and high-risk HBL has not been fully clarified. To address this issue, we carried out multi-omics analysis on 59 HBL samples to generate comprehensive profiles of gene mutation, copy-number alteration, DNA methylation and gene expression. By integrating these data, we aimed to unravel the heterogeneity of HBL and identify genetic determinants and therapy targets of high-risk HBL.

• Discovering novel mechanisms of taxane resistance in human breast cancer by whole-exome sequencing

  Taxanes are key drugs in the treatment of breast cancer, but some breast cancers are resistant to taxanes. Obtaining extensive genomic information in a short time has recently become possible. We used whole exome-sequencing (WES) to investigate mechanisms of taxane resistance in human breast cancer. We selected six patients with breast cancer whose tumors responded well to anthracycline treatment but grew rapidly during neoadjuvant taxane-based chemotherapy. We then performed WES of these samples and identified somatic mutations of candidate genes that are thought to affect taxane resistance.
