Disease relevance of Prostate

 

High impact information on Prostate

  • In vivo, androgen ablation increased PEDF in normal rat prostates and in human cancer biopsies [6].
  • By inhibiting the activity of arginase and nitric oxide synthase, key enzymes of L-arginine metabolism that are highly expressed in malignant but not in normal prostates, reduced tyrosine nitration and restoration of TIL responsiveness to tumor were achieved [7].
  • RESULTS: PGHS-1 immunostaining was localized to stromal fibroblasts and vascular endothelium in normal and cancerous prostates [3].
  • At 140 weeks of age, the animals were killed, and the prostates were removed and examined for histopathologic features in addition to being assayed for androgen concentrations [8].
  • The dihydrotestosterone content in normal prostates (mean +/- SE, 5.1 +/- 0.4 ng/g tissue) and in benign hyperplastic prostates (5.0 +/- 0.4) was similar [9].
 

Chemical compound and disease context of Prostate

 

Biological context of Prostate

  • Effects of androgen and polyamines on the phosphorylation of nucleolar proteins from rat ventral prostates with particular reference to 110-kDa phosphoprotein [15].
  • The staining for DNA breaks and the tTG staining also indicate that an increased rate of apoptosis is occurring transiently in these prostates [16].
  • Multiple binding sites for estradiol were observed in the cytosol as well as in the nuclear salt extractable and salt-resistant compartments of normal, benign hyperplastic, and cancerous human prostates [17].
  • We show that BMP7(lacZ/lacZ) null prostates show a two-fold increase in prostate branching, while recombinant BMP7 inhibits prostate morphogenesis in organ culture in a concentration-dependent manner [18].
  • When 2-yr-old dogs with starting prostates already at their maximum normal cellular content are subsequently treated for 4 months with dihydrotestosterone (DHT), such treatment induces an additional 2-fold abnormal proliferative increase in prostatic cell number above that seen in normal glands from untreated dogs of any age [19].
 

Anatomical context of Prostate

  • To investigate the mechanism of this synergism, cytosol androgen binding was measured by a density gradient technique in prostates of control and 17 beta-estradiol-treated castrate dogs [20].
  • Murine 8-lipoxygenase (8-LOX), homologue of the 15-LOX-2 enzyme that is expressed in benign human prostatic epithelium and reduced in Pca, was not detected in wild-type or LPB-Tag prostates as determined by enzyme assay, reverse transcription-PCR, and immunohistochemistry [21].
  • Using the substrate poly[Glu80Na,Tyr20] [poly(GT)] and the autoradiographic detection of alkali-resistant phosphoproteins after sodium dodecyl sulfate-polyacrylamide gel electrophoresis, tyrosine protein kinase (TPK) has been evidenced in human hyperplastic prostates (BPH) and the prostatic carcinoma cell lines PC3 and DU145 [22].
  • In contrast, pp125FAK and paxillin were up-regulated by androgen deprivation (castration) and further increased by estrogen treatment, which yielded metaplastic prostates mostly composed of proliferating basal epithelial cells [23].
  • Three weeks after transplantation, the animals were sacrificed by decapitation and a significant increase in plasma prolactin was observed, which was accompanied by a highly significant increase in the weights of seminal vesicles, ventral and dorsal prostates, and adrenals [24].
 

Associations of Prostate with chemical compounds

  • These findings fail to confirm the widespread belief that dihydrotestosterone content is elevated in benign hyperplastic prostates [9].
  • The compounds also reduced the concentration of testosterone in rat prostates by 35-75% [25].
  • The BB form of creatine kinase accounts for 98% of the activity in prostatic carcinoma and in prostates without cancer [10].
  • The photoaffinity labeling of the regulatory subunits of adenosine cyclic 3':5'-monophosphate-dependent soluble protein kinases with an adenosine cyclic 3':5' monophosphate analogue, 8-azidoadenosine cyclic 3':5'-monophosphate (8-N3-cAMP) was compared in normal prostates and prostatic (Dunning) tumors [26].
  • There was a gradual decrease in the vitamin A content of the prostates of the 4-HPR-treated group as compared with the control, such that by the end of the study period, the CON+4HPR group averaged 0.166 +/- 0.0827 (mean +/- SD) REs, whereas the CON group was 0.732 +/- 0.190 REs [27].
 

Gene context of Prostate

  • In prostates from mice in which the ERbeta gene has been inactivated (BERKO), androgen receptor (AR) levels are elevated, and the tissue contains multiple hyperplastic foci [28].
  • Abnormalities in Pten mutant skin consisted of mild epidermal hyperplasia, whereas prostates from these mice exhibited high-grade prostatic intraepithelial neoplasia (HGPIN) that frequently progressed to focally invasive cancer [29].
  • Treatment of developing prostates with SFRP1 in culture led to increased organ growth [30].
  • Conversely, GRP receptors were identified in only a few hyperplastic prostates and were localized in very low density in glandular tissue and, focally, in some stromal tissue [31].
  • The present study shows that the ERbeta gene is expressed together with ERalpha in normal prostates and NPECs, whereas it is barely detectable in prostate cancer and CPECS: Moreover, in some CPECs, the ERalpha gene may be transcribed in a changed protein, resulting from the expression of a deletion variant [32].
