• Adult B-precursor acute lymphoblastic leukemia RoCK and ROI single-cell transcriptome

  Whohle Transcriptome sequencing was performed following the manufactures protocol from BD Rhapsody. Capture of BCR::ABL1 was performed using RoCK and ROI. RoCK and ROI is based on barcoded beads of the BD Rhapsody platform. For RoCKseq specific capture, TSO oligos on BD Rhapsody beads are modified with a/ multiple capture sequence(s) specific to transcripts of interest. ROIseq, on the other hand, is based on specific primers which are spiked in during library generation, directing reads to regions of interest (ROIs). Multiple scRNAseq experiments were performed on several biological samples to validate RoCK and ROI.

• Whole genome sequencing data of paediatric KMT2A-rearranged acute lymphoblastic leukemia

  Pediatric KMT2A-rearranged leukemia is an aggressive subtype of leukemia commonly seen in infants (less tha 1 year old) and young children. It involves rearrangements of the KMT2A gene (formerly MLL) on chromosome 11q23, resulting in fusion genes that drive uncontrolled cell growth. This subtype is most often found in acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) and is associated with a poor prognosis. In infants, the 5-year event-free and overall survival rates are around 35–40%. Despite intensive chemotherapy, outcomes remain challenging, prompting ongoing research into targeted therapies and novel treatment strategies.

• B cell activation

  To investigate the gene programs involved in B cell activation and antibody switching, we profiled the gene expression at the single cell level as well as the antibody repertoire of human naive and memory B cells at resting and following three time points of activation. Through CRISPR perturbations, we defined IRF4 as a central regulator of both GC and plasma cell fates, acting independently of PRDM1 in GC commitment. Finally, leveraging machine learning classification methods trained solely on transcriptomic profiles, we accurately predicted sister cell relationships, revealing that plasma cell gene expression programs are heritable and tightly conserved within a clone.

• PD-associated regulatory variants in human dopaminergic neurons reveals modulators of SCARB2 and BAG3 expression

  SNPs have been associated with the risk of Parkinson’s disease but not in regulatory regions. While those potentially disrupt TFBS altering gene expression and contributing to cis-regulatory variation. To study changes in A and B compartment interactions and in topologically associated domains (TADs), we sequenced: - 3D chromatin contact using LowC, 6 samples. 3 replicates for each condition: smNPC (controls) cells and differentiated neurons after 30 days. Resulting paired-end are provided as BAM files. In order to confirm the predicted impact of the PD-associated allele of rs144814361 on BAG3 promoter, we proceeded with genome editing of the TH-REP1 cell line by using prime editing to insert the “T” allele at the position chr10:119651405 in the BAG3 promoter. - Chromatin accessibility using ATAC-seq, 9 samples of derived cell line TH-REP1. 3 replicates for each condition: 1) iPSC Wild Type 2) SNP-BAG3 variant in iPSC 3) SNP-BAG3 variant in smNPC. BAG3 variant: heterozygous for the SNP variant: rs144814361 (chr10 119651405) Resulting sequencing are provided as paired-end FASTQ files.

• Discordant_Monozygotic_Twins_ALS(Transcriptomics)

  Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder characterized by motor neuron degeneration. Despite known genetic contributions to both familial and sporadic ALS cases, much of ALS heritability remains unexplained, suggesting the involvement of other genetic and epigenetic factors. To address this gap, we used a comprehensive multi-omics approach, in a pair of Italian monozygotic twins discordant for ALS, integrating DNA methylation, transcriptomics, and whole exome sequencing (WES). Here we share transcriptomic data derived from bulk RNA-seq on RNA extracted from PBMCs of the twin pair. This analysis revealed distinct transcriptomic profiles underlying the discordant disease phenotypes.

• Transcriptional characterization of human innate lymphoid cells (ILCs) and natural killer (NK) cells from fresh umbilical cord blood

  The heterogenicity of cord blood ILCs (ILC1, ILC2, ILC3) and NK cells in humans has so far not been assessed. In this study, we sorted from fresh cord blood the respective cell types from 3 donors and performed single-cell transcriptome analysis. To achieve high resoluation, each sorted population was labelled individually via multiplexing antibodies and subsequent Abseq staining before pooling. To determine single-cell transcriptomes the BD Rhapsody pipeline was performed. This is the first data set to characterize human ILCs and NK cells at such depth.

• Bleomycin Induced Pneumonitis cohort of the Exceptional Responders Program of the Garvan Institute of Medical Research

  Bleomycin is a cytotoxic antibiotic and forms a key component of the curative-intent chemotherapy regimens for germ cell tumours (GCT) and lymphoma. However, the drug can be associated with a range of lung toxicity, including idiosyncratic inflammation termed bleomycin induced pneumonitis (BIP), which can lead to irreversible interstitial fibrosis and death. This study aims to identify germline genomic changes associated with BIP in patients receiving bleomycin as treatment for GCT or lymphoma, who develop clinically significant BIP despite low predicted risk based on absence of traditional risk factors.

• Spatial predictors of response to immunotherapy in microsatellite stable metastatic colorectal cancer

  Microsatellite stable (MSS) colorectal cancers (CRC) are largely unresponsive to immune checkpoint inhibition (ICI), prompting investigation into strategies to enhance sensitivity. The MAYA trial, which utilized temozolomide (TMZ) in MGMT-silenced MSS mCRC, hypothesized that TMZ-induced hypermutation could sensitize tumors to ICI. This phase II trial met its primary endpoint, demonstrating durable clinical responses with TMZ combined with ipilimumab and nivolumab. To elucidate factors in uencing response heterogeneity, we conducted multi-omic spatial pro ling of samples from patients who participated in the MAYA trial, including baseline and on-treatment tissue and blood specimens. While increased neoantigen load following TMZ exposure did not consistently predict for deep responses, spatial profiling revealed key determinants. Lymphocyte proportions, particularly CD8+KI67+ cells, within stromal and tumor compartments, along with macrophage composition (CD68+CD163+ cells) at the tumor-stromal interface, were predictive of response. Treatment pressures dynamically altered the tumor microenvironment composition and activated peripheral immune cells. This study is the first to identify spatial predictors of response to this promising novel treatment approach for MSS CRC.

• Identification_of_drug_resistance_genes_in_cancer_cell_lines_by_insertional_mutagenesis

  Our aim is to identify genes involved in resistance to anti-cancer therapies. In order to do this we have taken advantage of a lentiviral vector (LV)-based insertional mutagen to mutagenize cancer cell lines. LV-transduced cell lines were then treated with anti-cancer therapies and the emergence of resistant clones scored. DNA from pools of resistant clones was collected, subjected to custom capture by baits designed against the LV sequence, and then sequenced to identify the LV-genomic junction. We hope that the identification of recurrently targeted genes in resistant cell population will allow us to identify genes that mediate drug resistance.
