  Study EGAS00001007247

• Amplicon sequencing of melanoma samples

  The types of biomarkers for skin tumors have been 1) biochemical markers in blood, urine, and body fluid, 2) histopathological markers, 3) genetic examination of tumor tissue, 4) tumor-susceptibility assessed by germ_x0002_line genetic examination. Biomarkers in a blood are frequently used in the treatment of cutaneous malignancies, but are not suitable for early detection of malignancies. Research on circulating tumor cells, cell free DNA, exosomes has been promoted in recent years, but clinical application is halfway. Based on these circumstances, the purpose of this study is to search for biomarkers for diagnosis, therapeutic effect, and follow-up of skin tumors, and to verify their usefulness.

• 1. Identidication of molecular biological mechanism associated with the development and prognosis of uterine cancer, uterine sarcoma, and endometrial hyperplasia / 2. Identification of molecular biological mechanism associated with the development of endometriosis and malignant transformation, ovarian cancer, fallopian tubal cancer, peritoneal cancer, and other malignant tumors in gynecological organs

  To identify molecular subtypes and carcinogenesis in clear cell ovarian carcinomas by whole-exome sequencing, RNA-sequencing, and methylation array, and to characterize high-grade serous carcinomas by NGS-based, integrative genomic analyses, with focus on homologous recombination deficiency, molecular subtypes and prognositic factors.

• The study on genomic profiling using clinical specimens (tissue, blood, etc.) form patients with lung and thymic tumors

  The objective is to generate a comprehensive immunogenomic profiling in thymoma using RNA sequencing and TCR repertoire analysis and to evaluate the potential of immunotherapy in thymoma from multiple perspectives.

• Spatial transcriptome analysis for elucidating progression of early lung adenocarcinoma

  In this study, we performed spatial transcriptome analysis of adenocarcinoma in situ (AIS) and minimally invasive adenocarcinoma (MIA) to identify molecular events which occur during progression of ealry lung adenocarcinoma. For the analysis, we used cancer tissues which were precisely classified by Noguchi classification. Using the obtained data, we elucidated key molecular changes during tumor cell progression and their associated microenvironment statuses.

• Application of organoid culture system of human gastrointestinal and thoracic cancer in genome medicine

  In order to establish preclinical models, we have established a kind of lung cancer tumoroids derived from a mucus-producing solid pulmonary adenocarcinoma patient. We performed whole exome sequencing and RNA sequencing to analyze genetic background of the tumoroids.

  Study JGAS000664

• Application of organoid culture system of human gastrointestinal and thoracic cancer in genome medicine

  In order to establish preclinical models, we have established three kinds of lung cancer tumoroids derived from three different pulmonary large cell neuroendocrine carcinoma patients. We performed whole exome sequencing to analyze genetic background of these kinds of tumoroids.

• RNA sequencing of surgically removed lung adenocarcinoma afterwards treated with immune checkpoint inhibitors

  Patients with lung adenocarcinoma (LUAD) from The Cancer Genome Atlas (TCGA) database were enrolled in the training cohort to establish a prognostic signature based on the expression of tumor-specific amino acid metabolism related genes. The established signature was further investigated against an original cohort, KCC-ICI, of chemotherapy combined with immune checkpoint inhibitors. The signature consisting of nine genes, KYNU, PSPH, PPAT, MIF, GCLC, ACAD8, TYRP1, ALDH2, and HDC, could effectively stratify the OS in LUAD patients. The KCC-ICI cohort confirmed the predictive ability of the established signature in the clinical response to immune checkpoint blockade therapy, which correlated with the infiltration of immune cells (e.g., T lymphocytes and nature killer cells). We discovered that the high signature risk score patients showed a significantly lower concentration of plasma-free ??-aminobutyric acid (AABA).

• Unraveling the heterogeneity of multiple myeloma identifies therapy resistant subpopulation with vulnerability to the splicing pathway intervention

  Intra-tumor heterogeneity underlies the therapy resistance of multiple myeloma (MM). However, its details remain unknown. Here, we performed single-cell RNA sequencing coupled with VDJ targeted sequencing on highly purified bone marrow lineage marker-negative CD38+ MM cells from patients at diagnosis and in remission. This approach successfully subdivided MM cells into distinct clusters, unraveling their heterogeneity and plasticity on the axis of cell surface CD138 expression. Notably, unique clusters were identified in the minor CD138-negative population that resisted therapies. CRISPR/Cas9 screening of upregulated genes in the resistant population identified their vulnerability to the splicing pathway inhibition, among which RNA-binding protein 39 (RBM39) appeared to be overexpressed in the resistant population and involved in aberrant splicing. Genetic and pharmacological inhibition of RBM39 exerted a profound synthetic lethal effect on them. Our results unveil an uncharacterized subpopulation associated with therapy resistance and provide a novel therapeutic strategy targeting the splicing pathway in MM.
