The human hydroxysteroid SULT (sulphotransferase) 2B1 subfamily consists of two isoforms, SULT2B1a and SULT2B1b. These two isoenzymes are transcribed from the same gene by alternative splicing of their first exons and share 94% amino acid sequence identity. The SULT2B1 isoforms are highly selective for the sulphation of 3beta-hydroxysteroids. Immunoblot analysis of SULT2B1 expression in several...

PURPOSE We analyzed the expression of genes to identify reliable molecular markers in the diagnosis and progression of prostate cancer. EXPERIMENTAL DESIGN Gene expression profiling was done using HG-U133 set microarrays in 32 prostate cancer and 8 benign tissues of patients with cancer. Expression levels of 11 genes were selected for quantitative real-time PCR evaluation in 52 prostate cance...

BACKGROUND Markers that can discriminate between indolent and aggressive prostate tumours are needed. We studied gene methylation in non-neoplastic tissue adjacent to prostate tumour (NTAT) in association with prostate cancer mortality. METHODS From two cohorts of consecutive prostate cancer patients diagnosed at one pathology ward in Turin, Italy, we selected 157 patients with available NTAT...

BACKGROUND Inflammation has been strongly implicated in prostate carcinogenesis, but the precise molecular mechanisms linking inflammation and carcinogenic DNA damage are not known. Induction of the polyamine catabolic enzyme, spermine oxidase (SMO) has been linked to increased reactive oxygen species (ROS) and DNA damage in human gastric and lung epithelial cells and suggest direct mechanistic...

BACKGROUND. The prostate gland is a highly specialized organ with functional attributes that serve to enhance the fertility of mammalian species. Pathological processes affecting the prostate include benign prostate hypertrophy and prostate carcinoma; diseases that account for major morbidity and mortality in middle-aged and elderly men. To facilitate studies of biological processes uniquely re...

Background: Baculoviral IAP repeat containing 6 (BIRC6), a member of the inhibitors of apoptosis protein (IAP) family, has been reported to be correlated with oncogenesis. The aim of this study was to investigate the prognostic significance of BIRC6 in prostate cancer, as well as its effects on prostate cancer cell lines. Material/Methods: BIRC6 protein expression was investigated in 112 prosta...

background: certain marker studies have practical importance in the biology of prostate cancer. the purpose of this study was to determine whether the quantification of certain neuroendocrine and proliferative markers obtained during transurethral resection or prostatectomy, would help in the prognostic evaluation of prostatic adenocarcinomas.   methods: the present study was performed on sampl...

INTRODUCTION Prostate cancer in Indonesia is the 3rd ranking cancer among males and the 5th rank for their cancer mortality. Prognostic markers that can identify aggressive prostate cancer in early stages and help select appropriate therapy to finally reduce the mortality are therefore urgently needed. It has been suggested that stem cells in the prostate gland have a role in initiation, progre...

Transmembrane protease serine 4 (TMPRSS4) is a type-II transmembrane serine protease that plays an important role in the migration of cancer cells. This study aimed to investigate both the expression of TMPRSS4 and its clinical significance in prostate cancer. The expression of TMPRSS4 was evaluated in 73 pairs of prostate cancer and adjacent non-cancerous tissues by immunohistochemistry. The l...

Objective: To investigate the effect of ARA55 over-expression on the prostate cancer proliferation, aggression and apoptosis; to investigate whether ARA55 can regulate the expression of TGF-β or Smad7 in prostate cancer cells, and its relationship with estrogen receptor. Methods: The expression of ARA55, estrogen receptor α (ERα), ERβ, TGF-β and Smad7 was detected in human prostate cancer tissu...
