BACKGROUND Infected urachal remnant is an uncommon benign disease but is generally symptomatic and commonly recurs. The standard of care for this disease is complete resection of all anomalous tissue including a bladder cuff to avoid recurrence. Recent minimally invasive laparoscopic techniques can effectively manage this disease, but multiport laparoscopic(More)
The system L amino acid transporter (LAT) has an important role in the transport of various amino acids, and there have been reports about the relation of this system to cancer. Although LATs are highly expressed in the kidneys, little is known about their influence on human renal cancer. To clarify the role of LATs in human clear cell renal cell carcinoma(More)
The relationship between the clinicopathological features and molecular changes associated with standardized uptake value (SUV) determined by Positron emission tomography (PET) with [18F] fluorodeoxyglucose (18F-FDG PET) in human renal cell carcinoma (RCC) has not been elucidated. On the other hand, overactivation of the phosphatidylinositol 3’kinase(More)
Activation of Rho, one of the small GTPases, and its major downstream target Rho-kinase (ROCK) promotes the development and metastasis of cancer. We previously showed that elevation of Rho and ROCK expression was associated with tumor invasion, metastasis, and an unfavorable prognosis in patients with urothelial cancer of the bladder or upper urinary tract.(More)
Recently, it has become apparent that asparagine-linked (N-linked) oligosaccharide at an early stage of processing can play an important role in quality control of the secretory pathway. Here, we have developed a system for better understanding of the N-glycosylation machinery and its involvement in quality control in the endoplasmic reticulum (ER). Rough(More)
BACKGROUND Renal cell carcinoma (RCC) with sarcomatoid differentiation is invasive, refractory to treatment, and has a higher mortality. Therefore, systemic therapy is still challenging, and the curative resection of localized or locally advanced RCC with sarcomatoid differentiation is very important. Axitinib is a potent and selective second-generation(More)
To clarify the role of serum soluble T cell regulatory molecules in clear cell renal cell carcinoma (CCRCC), we measured the serum levels of soluble interleukin-2 receptor (sIL-2R), soluble B7-H3 (sB7-H3), and soluble cytotoxic T lymphocyte associated antigen-4 (sCTLA-4) in 70 CCRCC patients and 35 healthy controls. We investigated correlations between the(More)
We treated the high salt-washed canine pancreatic rough ER (KRM) with 0.18% Triton X-100, separated the extract from the residual membrane (0.18%Tx KRM), and processed the extract with SM-2 beads to recover membrane proteins in proteoliposomes. To focus on integral membrane proteins, KRM, 0.18%Tx KRM and proteoliposomes were subjected to sodium carbonate(More)
BACKGROUND Gleason pattern 3 less often has molecular abnormalities and often behaves indolent. It is controversial whether low grade small foci of prostate cancer (PCa) on biopsy could avoid immediate treatment or not, because substantial cases harbor unfavorable pathologic results on prostatectomy specimens. This study was designed to identify clinical(More)
INTRODUCTION/BACKGROUND Castration-resistant prostate cancer remains a therapeutic challenge, even after establishing the survival benefits of docetaxel chemotherapy. Metronomic chemotherapy stabilizes various cancers through antiangiogenic and immunomodulatory effects. We evaluate the activity of metronomic oral cyclophosphamide chemotherapy in metastatic(More)
