Recently, interest in the identification of non-invasive markers for prostate carcinoma detectable in the urine of patients has increased. In this study, we monitored the abundance of potential non-invasive markers of prostate carcinoma such as amino acid sarcosine, involved in the metabolism of amino acids and methylation processes, ongoing during the progression of prostate carcinoma. in addi...

EphA2 kinase regulates cell shape, adhesion, and motility and is frequently overexpressed in several cancers, including melanoma, prostate, breast, and colon cancers and lung carcinoma. Although a function in both tumor onset and metastasis has been proposed, the role played by EphA2 in tumor progression is still debated. In melanoma, EphA2 has been reported to affect cell migration and invasiv...

There is increasing evidence for the important role played by regulatory peptides in the physiology of the normal and neoplastic prostate. Adrenomedullin (AM) and pro-adrenomedullin N-terminal 20 peptide (PAMP) are recently discovered regulatory peptides widely expressed in the normal prostate and in prostate carcinoma. AM is produced in secretory, stroma, and endothelial cells and in neurons o...

BACKGROUND The objective of this study was to assess the utility of the bone formation marker procollagen type 1 amino-terminal propeptide (P1NP) in indicating bone metastases in patients with prostate carcinoma. Alkaline phosphatase (AP) and prostate-specific antigen (PSA) were measured as a comparison. PATIENTS AND METHODS The serum samples of 100 patients were analysed using a specific imm...

AIM To investigate the pathological features of the prostate biopsy through mass screening for prostate cancer in a Chinese cohort and their association with serum prostate specific antigen (PSA). METHODS A total of 12027 Chinese men in Changchun were screened for prostate cancer by means of the serum total prostate specific antigen tPSA test (by Elisa assay). Transrectal ultrasound-guided sy...

The growth and dissemination of tumors in the body has been associated with angiogenesis. Vascular endothelial growth factor (VEGF) is an angiogenic factor that stimulates endothelial cell growth and enhances vascular permeability. VEGF exerts its action by binding to specific cell surface receptors. Three receptors, VEGFR-1 (flt-1), VEGFR-2 (flk-1), and VEGFR-3 (flt-4) have been identified. Ve...

BACKGROUND A Total Quality Improvement review of frozen section diagnoses yielded four sequential false-negative frozen section diagnoses in lymph nodes in the evaluation of metastases from prostate carcinoma. Because these results appeared to differ from the department's overall frozen section experience, frozen section diagnoses of pelvic lymph nodes in patients with prostate carcinoma were r...

Primary squamous cell carcinoma is an uncommon tumor of the prostate gland. We report a 77-year-old male patient with urinary frequency and constipation. Fine needle biopsy from prostate was suspicious of squamous cell carcinoma of the prostate. Whole body positron emission tomography/computed tomography scan revealed high fluorodeoxyglucose uptake in prostate gland. Transurethral resection con...

the objective of the study was to evaluate thecytotoxic effects of aqueous fruit extract of cucumis melo in human prostate cancer cell line (pc-3) using mttand neutral red assays. the crude aqueous extract of c.melo was prepared by cold maceration method, filtered,concentrated and tested on pc-3 cell line. dose-dependent cytotoxic activitieswere exhibited by human prostate carcinoma pc-3 cell l...
