Prostate-specific membrane antigen (PSMA), a glutamyl preferring carboxypeptidase, is found in prostate and other carcinomas present on both tumor cells and associated microvascular lining cells. We find that the channel structures delineated by PSMA-expressing cells in human and rat prostate tumors are in functional continuity with the vasculature and thus form part of tumor microvasculature. ...
Prostate-specific membrane antigen (PSMA) is an integral, non-shed membrane glycoprotein that is a well-characterized and clinically validated marker of prostate cancer. The expression profile and other biological properties of PSMA make it an attractive target for antibody-drug conjugate (ADC) therapy of prostate cancer, as well as a broad range of other tumors in which PSMA is abundantly expr...
OBJECTIVES To explore the attitudes of men with confirmed or suspected prostate cancer to testing for prostate specific antigen. DESIGN Qualitative interview study with a purposive sample. SETTING Great Britain. PARTICIPANTS 52 men with suspected or confirmed prostate cancer, recruited through general practitioners, urologists, patient support groups, and charities. RESULTS Almost all m...
BACKGROUND Prostate-specific antigen (PSA) assays have historically produced different results. Our aim was to investigate the comparability of assay results of selected commercially available assay methods designed to measure total, free, or complexed PSA (tPSA, fPSA, and cPSA). METHODS We measured tPSA, fPSA, and cPSA in 70 samples and in the WHO PSA 96/670 reference preparation with 6 assa...
Prostate-specific membrane antigen (PSMA), a type II transmembrane protein, was originally thought to be strictly expressed in prostatic tissue, but recent studies have demonstrated PSMA protein expression in nonprostatic tumor neovasculature as well. Using immunohistochemistry, reverse transcription-PCR assays, and in situ hybridization, we have demonstrated PSMA mRNA transcripts and protein e...
A series of eight N-2-phenylethylphosphonyl derivatives of glutamic acid was prepared to determine if the inhibitory potency of a phenylethylphosphonyl derivative of glutamic acid against prostate-specific membrane antigen (PSMA) could be improved through rational substitutions on the phenyl ring. The design of these eight analogs was based upon the Topliss batchwise approach. Of the inhibitors...
PURPOSE We tested the hypothesis that serum isoform [-2]proPSA derivatives %p2PSA and Prostate Health Index are accurate predictors of prostate cancer in men scheduled for repeat biopsy. MATERIALS AND METHODS The study was an observational prospective evaluation of a clinical cohort of men with 1 or 2 previous negative prostate biopsies, with persistent suspicion of prostate cancer. They were...
Introduction. Prostate cancer (PC) leads the world structure of male mortality. Understanding prognosis for PC patients is vitally important and requires diagnostic enhancements such as developing biomarker panels. The studyaimed to estimate sensitivity, specificity, prognostic significance level immunoglobulin G (IgG) proteolysis products in blood serum depending on Gleason score detect how le...
OBJECTIVES To assess the use of post-salvage radiotherapy prostate-specific antigen for early prediction of biochemical failure or clinical recurrence after salvage radiotherapy in recurrent prostate cancer patients after prostatectomy. METHODS From 2000 to 2011, 164 patients were treated with salvage radiotherapy alone for recurrent prostate cancer. Patients who received androgen deprivation...
