BACKGROUND Prostacyclin (PGI2) enhances angiogenesis, especially in cooperation with bone marrow (BM)-derived endothelial progenitor cells (EPCs). However, the mechanisms of PGI2 in EPC-mediated angiogenesis in vivo remain unclear. The purpose of this study was to clarify the role of PGI2 in EPC-mediated angiogenesis using BM-specific IP deletion mice. (More)
BACKGROUND Non-small cell lung cancer (NSCLC) often has an epidermal growth factor receptor (EGFR) gene mutation. Growth of EGFR-gene-mutated NSCLC depends predominantly on EGFR signaling and requires a large amount of intracellular ATP to activate EGFR signal transduction. Nicotinamide phosphoribosyltransferase (NAMPT) is a rate-limiting enzyme in(More)
Notch signaling in tumorigenesis functions as an oncogene or tumor suppressor according to the type of malignancy. Numb represses intracellular Notch signaling. Previous studies have demonstrated that Notch signaling suppresses the proliferation of small cell lung cancer (SCLC) cell lines. However, in SCLC, the association between Notch1 and Numb expression(More)
Prostaglandin I2 (PGI2) agonist has been reported to reduce tumor metastasis by modifying tumor angiogenesis; however, the mechanisms of how PGI2 affects the endothelial cells or pericytes in tumor vessel maturation are still unclear. The purpose of this study was to clarify the effects of PGI2 on tumor metastasis in a mouse lung metastasis model using(More)
The limited number of available treatments for patients with small-cell lung cancer (SCLC) has prompted us to further investigate the biology of SCLC by molecular profiling. We collected formalin-fixed paraffin-embedded tumor samples from 127 patients with SCLC, who had undergone surgery at 16 institutions between January 2003 and January 2013, and analyzed(More)
OBJECTIVES Several American and Japanese guidelines recommend surgery for patients with c-stage I small-cell lung cancer (SCLC), whereas the European Society of Medical Oncology (ESMO) guidelines recommend surgery for patients with not only c-stage I but also c-stage II (T2N1) SCLC. In addition, previous studies identified various factors other than(More)
RATIONALE Type-2-associated goblet cell hyperplasia and mucus hypersecretion are well known features of asthma. 15-Lipoxygenase (15LO1) is induced by the Type-2 cytokines/IL-13 in human airway epithelial cells (HAEC) in vitro and is increased in fresh asthmatic HAECs ex vivo. 15LO1 generates a variety of products, including 15-hydroxyeicosatetraenoic acid(More)
Anaplastic lymphoma kinase (ALK) fusion oncogenes occur in approximately 3-5% of non-small cell lung cancer (NSCLC) cases. Various ALK inhibitors are in clinical use for the treatment of ALK-NSCLC, including the first generation ALK inhibitor, crizotinib, and recently the more highly potent alectinib and ceritinib. However, most tumors eventually become(More)
