• Transcriptome Analysis of Malignant Peripheral Nerve Sheath Tumor-like Melanoma

  Malignant peripheral nerve sheath tumor (MPNST)-like melanoma is a rare malignancy with overlapping characteristics of both neural sarcoma and melanoma. The genomics of MPNST-like melanoma have not been previously described. In this study, we performed whole transcriptome sequencing analysis in 8 samples from 6 patients diagnosed with MPNST-like melanoma. In correlation with deletion ofxa0SERPINB4xa0in all our samples, there was noxa0SERPINB4xa0mRNA expression in our cohort, suggesting a potential tumor-suppressor role of SERPINB4 in MPNST-like melanomas.xa0HRAS, a gene uncommonly mutated in cutaneous melanomas, was mutated in 2 patients, but with no increased mRNA expression.xa0BRAFxa0mRNA expression, resultant from an atypicalxa0BRAFxa0mutation, was increased in association with an inactivatingxa0NF1xa0mutation. Our data demonstrate the role of alternative mechanisms of RAS pathway activation in MPNST-like melanomas and suggest the potential role of other molecular pathways in its carcinogenesis.

• Conserved interferon-gamma signaling and decreased immune exclusion programs in responses to immune checkpoint blockade therapy_CM38-RNA

  We analyzed baseline and on-therapy tumor biopsies from 101 patients with advanced melanoma treated with nivolumab (anti-PD-1) alone or combined with ipilimumab (anti-CTLA-4). Analysis of whole transcriptome data showed that T cell infiltration and interferon-gamma signaling signatures corresponded most highly with clinical response to therapy, with a reciprocal decrease in cell cycle and WNT signaling pathways in responding biopsies. Clinical outcome differences were likely not due to differential melanoma cell responses to interferon-gamma, as 57 human melanoma cell lines exposed in vitro to this cytokine showed a conserved interferon-gamma transcriptome response unless they had mutations that precluded signaling from the interferon-gamma receptor. Therefore, the magnitude of the antitumor T cell response and the corresponding downstream interferon-gamma signaling are the main drivers of clinical response or resistance to immune checkpoint blockade therapy.

• RNAseq and ATACseq data, derived from HGSC cell lines pre- and post- treatment with an epigenetic compound

  These data consist of transcriptome and chromatin accessibility data (RNAseq and ATACseq respectively) derived from five High-Grade Serous Ovarian Carcinoma (HGSC) cell lines. HGSC lines included PEO1, PEO4, PEA2, OVCAR5 and OVCAR8. Samples were taken pre- and post-treatment with a novel epigenetic compound, HKMTi-1-005, which targets the activity of two histone methyltransferases, EZH2 and G9a.

• EED inhibition of organoid development

  Transcriptomics and epigenomics after chemical inhibition of EED during early human brain organoid development. To investigate the role of H3K27me3 inhibition during neuroectoderm induction, we treated brain organoids with 3 concentrations of EED inhibitor (and control) during the transition of pluripotency to neuroepithelium. At the neuroepithelium stage, we profiled the organoids using scRNA-seq (transcriptome) and bulk Cut&Tag (H3K27me3, H3K27ac). Library preparation for scRNA-seq was carried out with the 10x genomics platform.

• Whole transcriptome sequencing data of 3 histiocytic tumors with CLTC::SYK fusions

  The 3 tumor samples are PMLBM000JFR, PMLBM000JFT, and PMLBM000JFF. All samples are from different patients: Case 9 (PMLBM000JFR), Case 10 (PMLBM000JFT), and Case 12 (PMLBM000JFF) from the article by Kemps et al (Blood 2024 - In production). Methods: Total RNA was isolated and the generated libraries were sequenced on a NovaSeq 6000 (as described in Hehir-Kwa, et al. JCO Precis Oncol 2022). Data files: Provided are .cram and .crai files.

• Scywalker: scalable end-to-end data analysis workflow for nanopore single-cell transcriptome sequencing

  Existing nanopore single-cell data analysis tools showed severe limitations in handling current data sizes. We developed novel scalable methods for cell barcode demultiplexing and single-cell isoform calling and quantification and incorporated these in an easily deployable package called scywalker.

• RNAseq of organoid and fibroblast co-cultures

  The dataset includes whole transcriptome RNAseq BAM files of both organoids and fibroblast mono- and co-cultures with have been processed by Picard markdups. The experiment featured 6 fibroblast cell lines derived from 5 different early CRC biobank patients (pt10, pt12, pt15, pt19, pt22) as well as from different regions within those samples (normal tissue, core or invasive front). The organoids were generated from patient pt5 carcinoma samples.

  Whole-transcriptome sequencing (RNAseq) in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and controls. Differential expression patterns in genes involved in cilia, viral defense and NKT-cell specific pathways, suggesting a role of viral immunity in combination with cilia functionality in CRSwNP.
