To establish a more appropriate animal recipient for xenotransplantation, NOD/SCID/gamma(c)(null) mice double homozygous for the severe combined immunodeficiency (SCID) mutation and interleukin-2Rgamma (IL-2Rgamma) allelic mutation (gamma(c)(null)) were generated by 8 backcross matings of C57BL/6J-gamma(c)(null) mice and NOD/Shi-scid mice. When human CD34+(More)
The adipocyte-derived hormone adiponectin has been shown to play important roles in the regulation of energy homeostasis and insulin sensitivity. In this study, we analyzed globular domain adiponectin (gAd) transgenic (Tg) mice crossed with leptin-deficient ob/ob or apoE-deficient mice. Interestingly, despite an unexpected similar body weight, gAd Tg ob/ob(More)
Vascular endothelial growth factor (VEGF) is a well known factor that induces angiogenesis. Four isoforms, i.e. VEGF206, 189, 165, and 121, have been identified. We examined the isoform patterns of VEGF mRNA using reverse transcription polymerase chain reaction (RT-PCR) analysis in 61 colon cancers. All the colon cancers examined expressed VEGF121. The(More)
By using Southern blot analysis, we found that in two cases of human glioblastoma multiforme, cells carried amplified c-erbB genes which bore short deletion mutations within the ligand-binding domain of the epidermal growth factor (EGF) receptor. The products of these mutated c-erbB genes were about 30 kilodalton (kDa) smaller than the normal 170-kDa EGF(More)
Vascular endothelial growth factor (VEGF) has five isoforms (VEGF206, 189, 165, 145 and 121). Increased VEGF expression in renal cell carcinoma (RCC) is associated with angiogenesis, but, it is not apparent which isoform is involved in this effect. We examined the isoform patterns of VEGF by reverse transcription-polymerase chain reaction (RT-PCR) in 47(More)
Vascular endothelial growth factor (VEGF) is a major angiogenic factor. Osteosarcoma is characterised by hypervascularity and metastatic potential. We examined VEGF mRNA expression, VEGF isoform pattern and VEGF receptor (flt-1 and KDR) by RT-PCR analysis in 30 osteosarcomas. All 30 osteosarcomas expressed VEGF mRNA. 17 osteosarcomas (57%) expressed flt-1(More)
The calcium-binding protein, S100A4, with an inverse association of E-cadherin, is known to correlate with prognosis in various cancers. In this study, we investigated the expression of the S100A4 and E-cadherin status in relation to the clinicopathological parameters of pancreatic cancer. The expression status of these two proteins was examined in 72(More)
BACKGROUND The type 2 cytokine interleukin (IL)-10 has been reported to inhibit the antitumour activity of the regional immunity against various neoplasms. Certain lung cancers produce IL-10, but the clinical significance of IL-10 expression is not well understood. PATIENTS AND METHODS We examined IL-10 and IL-10 receptor (IL-10R) mRNA expression in 82(More)
A series of observations have indicated that tau, one of the major microtubule-associated proteins, is involved in neuronal cell morphogenesis and axonal maintenance. Tau is also the major component of paired helical filaments found in brains affected by Alzheimer's disease. To explore an as yet unidentified role of tau in vivo, approximately 11,000 mRNAs(More)
Multidrug resistance-associated protein (MRP) is one of the major factors for non-P-glycoprotein (PGp)-mediated multidrug resistance. We reported previously that overexpression of the MRP gene was related to the prognosis of non-small cell lung cancer (NSCLC). It is unclear how MRP expression is regulated in NSCLC. In this study, we examined MRP and mutant(More)
