BACKGROUND Pemetrexed is a key drug for therapy of non-small cell lung cancer (NSCLC). MATERIALS AND METHODS In a search for biomarkers for study of the efficacy of pemetrexed treatment, we examined the thymidylate synthase (TYMS) copy number in NSCLC cell lines and in clinical NSCLC samples treated with pemetrexed, combined with platinum drugs. RESULTS(More)
INTRODUCTION Amrubicin is a promising agent in the treatment of lung cancer, but predictive biomarkers have not yet been described. NAD(P)H:quinone oxidoreductase 1 (NQO1) is an enzyme known to metabolize amrubicinol, the active metabolite of amrubicin, to an inactive compound. We examined the relationship between NQO1 and amrubicinol cytotoxicity. (More)
OBJECTIVE The novel anthracycline agent amrubicin, has been approved in Japan to treat small and non-small cell lung cancers (SCLC and NSCLC). The present study evaluates the toxicity and effect of amrubicin especially in elderly patients with previously treated lung cancer. PATIENTS AND METHODS This retrospective study analyzed data from 51 patients (<70(More)
We report a case of paclitaxel-eluting stent implantation in an angina patient who developed interstitial pneumonia a few days afterward, and succumbed to fatal respiratory dysfunction despite corticosteroid therapy. Paclitaxel is an anti-neoplastic agent currently used as a coating substance for coronary stents to reduce the rate of restenosis. Pulmonary(More)
The c-MET receptor tyrosine kinase is the receptor for hepatocyte growth factor. Recently, activation of the c-MET/hepatocyte growth factor signaling pathway was associated with poor prognosis in various solid tumors and was one of the mechanisms of acquired resistance to epidermal growth factor receptor tyrosine kinase inhibitor, gefitinib. But the link(More)
BACKGROUND Vascular-type Ehlers-Danlos syndrome (vEDS) is a severe autosomal dominant inherited disorder resulting from mutations within the α1 type III collagen gene (COL3A1). The majority of published mutations are base changes leading to the substitution of single glycine residues within the triple-helical domain of type III collagen. Although clinical(More)
BACKGROUND Nestin is a class VI intermediate filament protein expressed in stem/progenitor cells during the development of the central nervous system. Nestin is detected in various types of tumors and is involved in malignant processes. This study investigated the expression and function of nestin in small-cell lung cancer (SCLC). METHODS Expression of(More)
The purposes of this study were to determine whether organic cation transporters (OCTs) can mediate platinum uptake, and whether OCT down-regulation confers resistance against cisplatin (CDDP) in cancer cells. Two lung cancer cell lines, PC-6 and PC-14, and their CDDP-resistant derivatives, PC-6/CDDP and PC-14/CDDP, were analyzed. OCT expression levels were(More)
BACKGROUND The cellular N-methyl-N'-nitroso-guanidine human osteosarcoma transforming gene (c-MET) protein is the receptor tyrosine kinase for hepatocyte growth factor. We recently found that c-MET protein expression and activation were enhanced in the majority of small cell lung cancer cell lines with cytotoxic anticancer drug resistance, and that(More)
