The androgen receptor (AR) is implicated in prostate cancer growth, progression, and angiogenesis. Hypoxia-inducible factor-1 (HIF-1), which transcriptionally regulates hypoxia-inducible angiogenic factors, is up-regulated in prostate cancers compared with adjacent normal tissues. HIF-1 may be involved in prostate cancer as well as the AR, but the(More)
PURPOSE We investigated whether urine survivin, an inhibitor of the apoptosis protein, is useful for diagnosing bladder tumor. METHOD We measured urine survivin levels in 40 patients with bladder tumors and 9 healthy volunteers. RESULTS The average urine survivin levels in the 40 patients and 9 healthy controls were not significantly different(More)
BACKGROUND We report here an extremely rare case of cystosarcoma phyllodes of the seminal vesicle. METHODS A 65-year-old man presented with urinary hesitancy, frequency and constipation. Clinical examinations including two needle biopsies were performed, and the patient had undergone open surgery. RESULTS The final pathological diagnosis was(More)
Transurethral resection of the prostate (TUR-P) has been established as the golden standard for the treatment of urinary retention in patients with benign prostatic hyperplasia (BPH). However, TUR-P is not performed on patients with certain high-risk complications. We have obtained favorable results using urethral stent (Angiomed-Memotherm) implantation to(More)
PURPOSE Hypoxia-inducible factor-1alpha (HIF-1alpha) is a transcriptional factor that regulates genes involved in the response to hypoxia. We evaluated the effects of HIF-1alpha over expression on the tumorigenic potency of renal cell carcinoma VMRC cells and bladder cancer EJ cells in vitro and in vivo. MATERIALS AND METHODS We introduced HIF-1alpha(More)
7S and 11S IgA (immunoglobulin A) levels in split ejaculates of 17 patients with chronic prostatis and 16 normal subjects were studied by the Hanson radial immunogel filtration method. The results suggest at least in certain cases of prostatitis increase of IgA level involves elevation of both types of IgA, and they are mainly of prostatic origin.
The recently identified prostate cancer susceptibility gene ELAC2 ( HPC2) harbors two common missense variants, a serine to leucine substitution at residue 217 (Leu217) and an alanine to threonine substitution at residue 541 (Thr541). We genotyped the two variants in a Japanese cohort consisting of 350 prostate cancer patients 242 male population controls,(More)
PURPOSE We evaluated usefulness of transcatheter arterial embolization (TAE) for deep renal injury, and investigated whether there is any difference in outcomes for transcatheter arterial embolization (TAE) performed for deep renal injury in a large-sized hospital (university hospital) in comparison with a middle-sized hospital (local hospital). METHODS(More)
We describe a prostate cancer patient whose initial symptom was intermittent double vision. Intracranial magnetic resonance imaging demonstrated a pituitary mass extending to the cavernous sinus, which caused the double vision. After hormonal therapy for prostate cancer, the pituitary mass disappeared, and double vision was completely resolved without local(More)
Intravesical bacillus Calmette-Guerin (BCG) therapy is considered the most successful immunotherapy against solid tumors of human bladder carcinoma. To determine the actual effector cells activated by intravesical BCG therapy to inhibit the growth of bladder carcinoma, T24 human bladder tumor cells, expressing very low levels of class I MHC, were(More)
