The methylation status of 7 genes was examined in four cell lines, 36 samples of benign prostatic hyperplasia (BPH), 20 samples of prostatic intraepithelial neoplasia (PIN) and 109 samples of prostate cancer (PCa), using methylation-specific PCR (MSP): the pi-class glutathione S-transferase (GSTP1), retinoic acid receptor beta 2(RARbeta2), androgen receptor(More)
Ovarian clear cell carcinoma (CCC) arises from ovarian endometriosis. Intra-cystic fluid contains abundant amounts of free iron, which causes persistent oxidative stress, a factor that has been suggested to induce malignant transformation. However, the mechanisms linking oxidative stress and carcinogenesis in CCC currently remain unclear. Lipocalin 2(More)
OBJECTIVE To assess the incidence of benign renal lesions in our Japanese clinical experience with surgical resection. METHODS A total of 411 renal masses harvested by radical or partial nephrectomy between January 1991 and April 2011 at our institution were retrospectively assessed. The incidence of benign lesions in 1-cm increments in diameter was(More)
A case of malignant phyllodes tumor of the prostate in a 67-year-old man is reported. The patient was referred to a hospital for urinary retention. From material taken at three transurethral resections of the prostate (TURP), a histological diagnosis of benign prostatic hyperplasia was made. However, at the fourth TURP, phyllodes tumor was diagnosed due to(More)
We demonstrated the effects of short- and long-term administration of cacao mass on anxiety in the elevated T-maze test, which is an animal model of anxiety. In the first study, we administered cacao mass (100 mg/100 g body weight) per os and immediately performed the elevated T-maze test. Short-term cacao mass significantly abolished delayed avoidance(More)
Renal cell carcinoma (RCC) is an angiogenesis-dependent and hypoxia-driven malignancy. As a result, several targeting agents are being investigated. However, the efficacy of current regimens is generally insufficient for their toxicity and poor overall response rates. We have recently reported that naftopidil exerts growth-inhibitory effects on human(More)
A 20-year-old unmarried Ghanaian man complaining of macroscopic hematuria and cystitis symptom was admitted to our institute. Abdominal ultrasound revealed a hyper echoic lesion in the entire bladder wall. Computed tomography showed a calcification of the whole bladder wall and of the left lower ureter. Flexible cystoscopy revealed many nodular masses,(More)
Transcriptional silencing of cancer-related genes by DNA methylation is observed in various cancers. To identify genes controlled by methylation in prostate cancer, we used cDNA microarray analysis to investigate gene expression in prostate cancer cell lines LNCaP and DU145 treated with a methyltransferase inhibitor alone or together with a histone(More)
PURPOSE To evaluate the long-term outcomes and safety photoselective vaporization of the prostate (PVP). PATIENTS AND METHODS From April 2005 to December 2015, a total of 1154 patients with benign prostatic hyperplasia underwent PVP. The type of Green Light laser was an 80 W potassium-titanyl-phosphate laser and later a 120 W lithium triborate laser.(More)
