• Type I Interferon and Cycling Lymphocytes in Macrophage Activation Syndrome

  We performed immune profiling of peripheral blood mononuclear cells from patients with Still's disease and macrophage activation syndrome (MAS) using bulk RNA sequencing and single-cell RNA sequencing. Three groups were included in the study: healthy controls, patients with Still's disease without macrophage activation syndrome, and patients with Still's disease and macrophage activation syndrome. We found that macrophage activation syndrome is associated with transcriptomic signatures of interferon upregulation and cell cycling. We identified cycling lymphocytes within T cell and NK cell populations that are correlated with MAS disease activity. All sequencing data are available through dbGaP.

• Whole Exome Sequencing of 60 tumor/normal matched liver Cancers (HCC)

  The French ICGC project on liver tumors is coordinated by Pr Jessica Zucman-Rossi and funded by Inca (French Institute for Cancer). The aim of the present project is to identify the catalog of somatic and germline mutations in liver tumors using whole genome (WGS) and whole exome sequencing (WGS), integrated with DNA methylation and RNA sequencing (RNA-seq) data. The present series corresponds to 60 whole exome tumor/normal pairs with matched RNA-seq. Hepatocellular carcinoma (HCC) accounts for more than 90% of liver cancers, and is a major health problem. It is the 3rd cause of cancer-related mortality. Advances in genomic analyses have formed a comprehensive understanding of different underlying pathobiological layers resulting in hepatocarcinogenesis. Thus, the development of next-generation sequencing technologies has made it possible to generate more comprehensive catalogues of somatic alteration events (single nucleotide substitutions, structural variations, and epigenetic changes) in liver cancer genome than ever before.

• Identification of Recurrent SMO and BRAF Mutations in Ameloblastomas

  RNA-seq data from two cases of ameloblastoma was analyzed for candidate gene fusions and point mutations. Recurrent point mutations identified in the RNA-seq data, as well as mutations identified with limited panel targeted deep sequencing, were validated as somatic. Expanding to a larger cohort of 28, one of two activating mutations was found in 80% of cases. No recurrent gene fusions events were identified.

• Atezolizumab monotherapy following dCRT indicated a promising cCR rate in patients with unresectable locally advanced esophageal squamous cell carcinoma (EPOC1802)

  The objective is to analyze tumor and normal cell exome sequencing of esophageal cancer patients participating in the Tenergy trial before treatment and RNA sequencing specimens of tumor biopsy specimens at three points before treatment, after radiation chemotherapy, and after atezolizumab administration, in order to search for biomarkers to predict treatment response. Exome sequencing of pretreatment tumor tissue (27 specimens) and normal tissue (27 specimens) from esophageal cancer patients participating in the Tenergy trial, and RNA sequencing of tumor biopsy specimens at three time points before treatment (28 specimens), after radiation chemotherapy (25 specimens) and after atezolizumab administration (25 specimens).

• "Elucidation of Immune Status and Its Clinical Significance in Patients with Solid Tumors, Including Gastrointestinal Cancers": A Phase II Clinical Trial of Lenvatinib Plus Pembrolizumab in Patients with Advanced Gastric Cancer

  The objective is to analyze tumor and normal cell exome sequencing of gastric cancer patients participating in the EPOC1706 trial before treatment and RNA sequencing specimens of tumor biopsy specimens at two points before treatment and after the combination therapy of Lenvatinib plus pembrolizumab, in order to search for biomarkers to predict treatment response. Exome sequencing from 10 gastric cancer patients participating in the EPOC1706 trial, and RNA sequencing of tumor biopsy specimens at two time points before treatment (9 patients) and after the combination therapy (8 patients) were obtained.

• The Role of ZEB2 during Human Neural Crest Cell Formation

  This study examined the role of ZEB2 during human neural crest cell formation. Human neural crest cells were differentiated from WiCell H1 human embryonic stem cells (WA01). Genome-wide transcriptional analysis (RNA-seq) was performed at day-3 and day-5 of human neural crest cell formation following siRNA knockdown of ZEB2 and using an N-terminal ZEB2 mutant H1 human embryonic stem cell line generated using CRISPR genome editing. RNA-seq was also performed on edited and unedited H1 human embryonic stem cells. ATAC-seq analysis was performed at day-3 and day-5 human neural crest differentiated from the N-terminal ZEB2 mutant embryonic stem cell line. Together, these data reveal the regulatory role of ZEB2 in the human neural crest gene regulatory network. We provide raw sequencing files for all RNA-seq and ATAC-seq samples.

• Dysregulation of Alternative Splicing Is a Transcriptomic Feature of Patient Derived Fibroblasts From CAG Repeat Expansion Spinocerebellar Ataxias

  The aim of this study was to characterize transcriptomic changes in patient-derived cell lines of CAG repeat expansion spinocerebellar ataxias (SCAs), using RNA-sequencing (RNA-Seq), to help us better understand disease pathogenesis. The data consists of two SCA1, two SCA3, and one SCA7 cell lines with 5 unaffected controls. Widespread alternative splicing dysregulation was identified across all SCA cell lines. Alternative splicing analysis also revealed that the dysregulation affected disease-relevant pathways with novel skipped-exon splicing events from the RNA-Seq data validated with RT-PCR. These findings are consistent with a previous study that identified robust transcriptomic dysregulation, specifically at the splicing level, in SCA1, -3, and -7 mouse models even at presymptomatic ages. Therefore, alternative splicing has the potential to be used as a biomarker not only in mouse models, but also patient models of repeat expansion SCAs.
