Transglutaminase 4 (TG4) is a member of the enzyme family that catalyzes the calcium-dependent post-translational modification of proteins via cross-linking, polyamination, or deamidation. TG4 exhibits prostate-specific expression pattern and plays a crucial role in the formation of the copulatory plug in rodents. However, the physiological function(s) of human TG4 remains speculative. Human TG...

PURPOSE To analyze rates of expression of karyopherin alpha 2 (KPNA2) in different prostate tissues and to evaluate the prognostic properties for patients with primary prostate cancer. EXPERIMENTAL DESIGN Tissue microarrays (TMA) contained 798 formalin-fixed, paraffin-embedded prostate tissue cores from two different institutes of pathology. TMAs were stained immunohistochemically for KPNA2 a...

normal 0 false false false en-us x-none ar-sa background: prostate cancer is one of the most common cancer types both in western and eastern countries, involving mostly elder men. the mechanisms underlying the prostate cancer development remain unclear. prostate-specific antigen (psa) is the only well accepted marker for prostate cancer diagnosis and prognosis. the diagnosis and treatment of pr...

Prostate cancer (PCa) remains one of the most widespread and perplexing of all human malignancies. Assessment of gene expression is thought to have an important impact on cancer diagnosis, prognosis and therapeutic decisions. In this context, we explored combined expression of PCa related target genes AMACR and PCA3 in 126 formalin fixed paraffin embedded prostate tissues (FFPE) from Moroccan p...

Prostate cancer (PCa) is the most frequently diagnosed type of cancer in developed countries. The decisive method of diagnosis is based on the results of biopsies, morphologically evaluated to determine the presence or absence of cancer. Although this approach leads to a confident diagnosis in most cases, it can be improved by using the molecular markers present in the tissue. Both miRNAs and p...

BACKGROUND/AIM The purpose of the present study was to investigate whether endothelial nitric oxide synthase (eNOS) gene polymorphisms play a role in prostate cancer (PCa). MATERIALS AND METHODS We examined three eNOS gene polymorphisms (T-786C promoter region, G894T, and Intron 4 VNTR 4a/b) at extracted DNAs from 50 formalin-fixed paraffin-embedded tissues of PCa patients. For the controls, ...

To explore the expressions level of Livin, Survivin and Caspase-3 in prostatic cancer and the relationship among the 3 proteins and the clinicopathological features as well as the correlation among them. Totally, 43 paraffin-embedded prostate cancer tissues obtained from patients who were performed with rectal prostate biopsy or excision and 17 paraffin-embedded prostatic hyperplasia tissues we...

The Transplex Complete Whole Transcriptome Amplification (WTA2) Kit has been enhanced to effectively amplify damaged RNA. Total RNA samples isolated from matched FFPE (formalin-fixed paraffin-embedded) and frozen prostate tissues (malignant and normal) were amplified with the Transplex WTA2 Kit and analyzed on Agilent Whole Genome expression microarrays. A call rate of >65% was observed for com...

We profiled the expression of genes in benign and untreated human prostate cancer tissues using oligonucleotide microarrays. We report here 50 genes with distinct expression patterns in metastatic and confined tumors (Gleason score 6 and 9; lymph node invasive and noninvasive). Validation of expression profiles of 6 genes by quantitative PCR revealed a strong inverse correlation in the expressi...
