BACKGROUND Trichophyton rubrum and Trichophyton mentagrophytes human-type (synonym, Trichophyton interdigitale (anthropophilic)) are major causative pathogens of tinea unguium. For suitable diagnosis and treatment, rapid and accurate identification of etiologic agents in clinical samples using reliable molecular based method is required. OBJECTIVE For(More)
INTRODUCTION Human antigen R (HuR) regulates the stability of mRNA and is associated with cell proliferation, angiogenesis, and lymphangiogenesis. However, the clinical significance and pathological role of HuR in bladder cancer remains unclear. The main objective of this investigation was to clarify the relationships between HuR expression and clinical(More)
BACKGROUND The clinical significance of prostaglandin E2 receptor (EPR) expression in renal cell carcinoma (RCC) tissues remains unclear. Patients and Μethods: Four subtypes of EPRs were examined in 112 human RCC tissues by immunohistochemical and Western blot analysis. The relationships between EPR immunoreactivity score (IS) and various pathological(More)
BACKGROUND c-Fes is a proto-oncogene encoded non-receptor protein-tyrosine kinase (PTK). However, genetic studies have indicated that it has anti-tumorigenic effects in certain cancers. The pathological and clinical significance of c-Fes in prostate cancer are unknown. METHODS Expression of c-Fes was evaluated in normal glands, prostatic intraepithelial(More)
X-linked inhibitor of apoptosis (XIAP) has high affinity and strong inhibitory activity on apoptosis-related caspase-3. The relationships between expression of XIAP and cleaved caspase-3, and response to neo-adjuvant hormonal therapy (NHT) remain elusive. The aim was to investigate whether NHT influences with XIAP expression in prostate cancer patients. In(More)
Angiogenesis plays an important role in cancer progression in many types of cancer. Evaluation of angiogenesis is often performed, but the optimal methodology for human cancer has not been agreed upon. As adequate evaluation of angiogenesis in cancer tissues might be important for prediction of prognosis and treatment decisions, we evaluated angiogenesis(More)
OBJECTIVE To clarify the detailed pathologic roles of prostaglandin E(2) in prostate cancer tissues, the present study investigated the clinical significance and prognostic roles of the density of tumor-associated stromal cells expressing specific receptors for prostaglandin E2, termed "E-prostanoid (EP)1-4 receptors (EP1R-4Rs)." METHODS The expression of(More)
Thrombospondin (TSP) is a multi-functional protein that appears to have dual roles in cancer, that is, either as a promoter or a suppressor. 4N1K is a TSP-derived peptide that has been reported to be associated with neovascularity, cell survival, and invasion. There is a little information regarding its pathological roles in human cancer tissues. Our aim(More)
Patients on hemodialysis are at higher risk of renal cell carcinoma probably because of inflammatory and immune system disorders. The aim of this study was to clarify the pathologic roles of 2 phenotypes of mast cells, mast cell tryptase and mast cell chymase, and their correlation with stem cell factor and protease-activated receptor 2 in patients with(More)
OBJECTIVES To clarify the clinical and prognostic significance of cortactin and phosphorylated cortactin in patients with sarcomatoid renal cell carcinoma (SRCC). METHODS We retrospectively reviewed the data from 31 patients with SRCC and 33 with conventional renal cell carcinoma matched for clinicopathologic features. The immunoreactive score for(More)
