Recent efforts have been aimed at targeting the hypoxia inducible factor (HIF)-mediated hypoxia-induced gene pathway for renal cell carcinomas (RCC) therapy. Among the various genes induced by HIF, vascular endothelial growth factor (VEGF) is one of the critical mediators in angiogenesis, tumor growth and metastasis. To date, however, limited information is(More)
PURPOSE To investigate a method of diagnosing angiomyolipoma that contains minimal fat. MATERIALS AND METHODS In six cases of angiomyolipoma with minimal fat, the attenuation on contrast material-enhanced and unenhanced computed tomographic (CT) images, the echogenicity on sonograms, the signal intensity on T2-weighted magnetic resonance (MR) images, and(More)
Frozen feline semen was prepared using two types of extenders, egg yolk Tris-fructose citric acid (EYT-FC) and egg yolk sodium citrate solution (EYC), and the semen qualities after thawing and the conception rates obtained by unilateral intrauterine horn insemination (UIUI) were investigated. Cats used in the experiment were six males and 11 females aged(More)
CONTEXT The natural history of renal cell carcinoma (RCC) is highly unpredictable. Small renal masses may be accompanied by metastatic disease. Conversely, patients with locally advanced disease may enjoy long-term disease-free survival. OBJECTIVE To review the status of prognostic factors in RCC. EVIDENCE ACQUISITION A literature review was performed(More)
Xeroderma pigmentosum (XP) and Cockayne syndrome (CS) are rare autosomal recessive disorders associated with a defect in the nucleotide excision repair (NER) pathway required for the removal of DNA damage induced by UV light and distorting chemical adducts. Although progressive neurological dysfunction is one of the hallmarks of CS and of some groups of XP(More)
PURPOSE To correlate the enhancement pattern of double-phase helical computed tomography (CT) of small renal parenchymal neoplasms with pathologic findings and tumor angiogenesis, and evaluate whether the enhancement pattern would be useful in differentiating the histomorphologic types of small renal parenchymal neoplasms. MATERIALS AND METHODS(More)
We have examined the expression of chemokines and their receptors in the atopic dermatitis-like (AD-like) lesions of NC/Nga mice. Such lesions develop when the mice are kept in conventional conditions, but not when they are kept isolated from specific pathogens. The thymus- and activation-regulated chemokine TARC is unexpectedly highly expressed in the(More)
1. In our search for compounds that inhibit the binding of [3H]-substance P (SP) to guinea-pig lung membranes, the dipeptide SP antagonist, FK888, was developed by chemical modification of the parent compound, (D-Pro4, D-Trp7,9,10, Phe11)SP4-11. 2. In a [3H]-SP binding assay using guinea-pig lung membranes and rat brain cortical synaptic membranes, FK888(More)
PURPOSE Signal transducer and activator of transcription 3 (STAT3) is known to have an important role in cytokine and growth factor signaling pathways. In various types of human malignant tumors STAT3 has been shown to be constitutively activated due to aberrant production of cytokines and growth factors. We examined the presence of STAT3 activation and its(More)
BACKGROUND The cross-talk between Wnt signaling and the Akt pathway in prostate cancer (Pca) is still unclear. In the present study, we found that WIF-1 downregulates the Akt pathway and also enhances chemosensitivity in PTEN-null Pca cells. METHODS Wnt inhibitory factor-1 (WIF-1), an inhibitor of Wnt proteins, was transfected into PC-3 and DU145 Pca(More)
