OBJECTIVE To evaluate the influence of polymorphisms in GSTA1, GSTM1, GSTT1, and GSTP1 in the risk of developing Prostate Cancer (PCa) in a population of Rio de Janeiro and compare the distribution of allele and genotype frequencies of the polymorphisms analyzed in the present study population with other regions in the country and different ethnic groups. MATERIALS AND METHODS We analyzed a s...

BACKGROUND Though androgen deprivation therapy is the standard treatment for prostate cancer (PCa), most patients would inevitably progress to castration-resistant prostate cancer (CRPC) which is the main cause of PCa death. Therefore, the identification of novel molecular mechanism regulating cancer progression and achievement of new insight into target therapy would be necessary for improving...

BACKGROUND The low specificity of the prostate-specific antigen (PSA) test makes it a poor biomarker for early detection of prostate cancer (PCA). Because single biomarkers most likely will not be found that are expressed by all genetic forms of PCA, we evaluated and developed a proteomic approach for the simultaneous detection and analysis of multiple proteins for the differentiation of PCA fr...

Background: Management of postoperative pain after caesarean section (CS) requires a balance between pain relief and undesirable side effects of drugs and technique. In order to improve postoperative pain management after caesarean section, we compared intravenous patient controlled analgesia (IV-PCA) with our current hospital practice, which is continuous opioid infusion. Method: We enrolled o...

Tumor protein D54 (TPD54) has been reported to be involved in the prognosis of several cancers. However, the involvement of TPD54 in prostate cancer (PCa) is yet to be elucidated. In the present study, 117 patients with PCa were enrolled. The mRNA and protein levels of TPD54 in PCa tissues and adjacent normal prostate tissues were analyzed by quantitative polymerase chain reaction and western b...

Integrated analysis of metabolomics, transcriptomics and immunohistochemistry can contribute to a deeper understanding of biological processes altered in cancer and possibly enable improved diagnostic or prognostic tests. In this study, a set of 254 metabolites was determined by gas-chromatography/liquid chromatography-mass spectrometry in matched malignant and non-malignant prostatectomy sampl...

Proteome analysis of the urine has shown that urine contains disease-specific information for a variety of urogenital system disorders, including prostate cancer (PCa). The aim of this study was to determine the protein components of urine from PCa patients. Urine from 8 patients with clinically and histologically confirmed PCa was analyzed by conventional 2D PAGE. The MS identification of the ...

OBJECTIVES To estimate the 2010 incidence of PCa in Spain and describe the clinical profile of newly-diagnosed cases using a nationwide hospital-based registry. MATERIAL AND METHODS National epidemiological study in 25 public hospitals with a specific reference population according to the National Health System. Sociodemographic and clinical variables of all newly diagnosed, histopathological...
