Previous studies have shown dose-dependent growth inhibition of the human mammary carcinoma cell line MDA-MB-231 xenotransplanted in athymic mice using retinol. In this study, the growth inhibitory effect of retinoic acid (RA) and 13-cis-retinoic acid (13-cis-RA) was examined in vitro and in vivo. With both agents there was dose-related growth inhibition in monolayer culture. The MDA-MB-231 cel...
PURPOSE No lung cancer xenograft model using non-obese diabetic (NOD)-scid Il2rg (-/-) mice has been reported. The purpose of this study is to select a suitable mouse strain as a xenogenic host for testing tumorigenicity of lung cancer. MATERIALS AND METHODS We directly compared the susceptibility of four immunodeficient mouse strains, c-nu, C.B-17 scid, NOD-scid, and NOD/LtSz-scid Il2rg (-/-...
Bone marrow of breast cancer patients was found to contain CD8(+) T cells specific for peptides derived from breast cancer-associated proteins MUC1 and Her-2/neu. Most of these cells had a central or effector memory phenotype (CD45RA(-)CD62L(+) or CD45RA(-)CD62L(-), respectively). To test their in vivo function, we separated bone marrow-derived CD45RA(+) naive or CD45RA(-)CD45RO(+) memory T cel...
BACKGROUND/AIMS Discosoma sp red fluorescent protein (DsRed2) is a newly developed marker for in vivo labeling studies in different biologic systems. After vector transfection, DsRed2 is expressed in mammalian cells and can be detected by fluorescence microscopy. The aims of this study were to establish a DsRed2-transfected human rhabdomyosarcoma (RMS) cell line and to perform a xenotransplanta...
Rhabdomyosarcoma (RMS) is a childhood cancer originating from skeletal muscle, and patient survival is poor in the presence of metastatic disease. Few determinants that regulate metastasis development have been identified. The receptor tyrosine kinase FGFR4 is highly expressed in RMS tissue, suggesting a role in tumorigenesis, although its functional importance has not been defined. Here, we re...
Carbonic anhydrase IX (CA9) is a membrane-associated carbonic anhydrase that regulates cellular pH, is upregulated in various solid tumors, and is considered to be a therapeutic target. Here, we describe the essential role of CA9 in the tumorigenicity of cells derived from human adult T-cell leukemia/lymphoma (ATL). We previously established the highly tumorigenic ST1-N6 subline from the ATL-de...
BACKGROUND Osteosarcomas (OS) are aggressive neoplasms with a wide range of morphologic patterns. MATERIALS AND METHODS OS cases (primary and xenotransplanted) with paraffin blocks available were collected and included in tissue microarrays (TMAs). A morphologic evaluation including the different passages in mice was carried out according to the new WHO criteria. In addition, TMAs were analyz...
