Deletions of chromosome arm 13q belong to the most frequent molecular alterations in prostate cancer. To better understand the role of 13q deletion in prostate cancer we took advantage of our large prostate cancer tissue microarray comprising more than 12,000 cancer samples with full pathological and clinical follow up data. Fluorescence in situ hybridization with probes for ENOX1 (13q14.11) and the retinoblastoma gene (RB1, 13q14.2) was employed. A 13q deletion was found in 21% of 7,375 analyzable cancers...

INTRODUCTION: The prostate-specific antigen (PSA) based prostate cancer (PC) screening is currently being debated. The current assessment is to understand the variability of detecting high-risk PC in a NZ cohort in comparison to a US cohort with better PSA screening facilities. Aldo-keto reductase 1C3 (AKR1C3) is known for multiple functions with a potential to regulate subsequent PSA levels. Therefore, we wish to understand the influence of tobacco smoking and the AKR1C3 rs12529 gene polymorphism in this variability...

From the advent of the Gleason grading system for prostate cancer, cancer displaying intraluminal necrotic cells and/or karyorrhexis within cribriform/solid architecture, a phenomenon termed "comedonecrosis," has been assigned pattern 5. Intraductal carcinoma (IDC-P) shows morphologic overlap with high-grade cribriform/solid adenocarcinoma architecturally and cytologically and may also show central necrosis, yet due to the presence of basal cells at the duct periphery is not currently assigned a grade in clinical practice...

Monoamine oxidase A (MAOA) is a mitochondrial enzyme, which degrades monoamine neurotransmitters and dietary amines and produces H2 O2 . Recent studies have shown increased MAOA expression in prostate cancer (PCa), glioma, and classical Hodgkin lymphoma. However, the biological function of MAOA in cancer development remains unknown. In this study, we investigated the role of MAOA in the development of prostate adenocarcinoma by creating a prostate-specific Pten/MAOA knockout (KO) mouse model, in which MAOA-floxP mouse was crossed with the conditional Pten KO PCa mouse that develops invasive PCa...

Histone methylation is essential for gene expression control. Trimethylated lysine 27 of histone 3 (H3K27me3) is controlled by the balance between the activities of JMJD3 demethylase and EZH2 methyltransferase. This epigenetic mark has been shown to be deregulated in prostate cancer, and evidence shows H3K27me3 enrichment on gene promoters in prostate cancer. To study the impact of this enrichment, a transcriptomic analysis with TaqMan Low Density Array (TLDA) of several genes was studied on prostate biopsies divided into three clinical grades: normal ( n = 23) and two tumor groups that differed in their aggressiveness (Gleason score ≤ 7 ( n = 20) and >7 ( n = 19))...

Prostate cancer is the most common malignancy in men, and biologically shows highly heterogeneous clinical outcomes, despite early detection. Therefore, the identification of novel molecular markers that are associated with biological aggressiveness is very important for prostatic cancer clinical outcome predictions and treatment choices. Here, we investigate quiescin sulfhydryl oxidase 1 (QSOX1) expression and evaluate its clinicopathological significance and prognostic impact in prostate cancers, with immunohistochemistry on tissue microarrays...

Extended prostate needle core biopsies are standard of care for the diagnosis of prostatic carcinoma. Subsequent biopsies may be performed for a variety of indications. Knowledge of biopsy characteristics indicating risk for progression may have utility to guide therapeutic management. Prostate needle core biopsies performed between 2008-2014 were reviewed. Patients with at least 1 subsequent biopsy were identified. Cases were categorized by worst initial diagnosis. Gleason ≤6 carcinoma was further classified as significant or insignificant with insignificant defined as: ≤2 cores with carcinoma, sites with ≤50% carcinoma, and unilateral carcinoma...

HSD3B2 plays a crucial role in steroid hormone biosynthesis and is thus of particular interest in hormone dependent tumors such as prostate cancer. To clarify the clinical relevance of HSD3B2 expression in prostate cancer, we analyzed HSD3B2 protein expression by immunohistochemistry on our preexisting tissue microarray with 12.247 annotated cancers. Compared with normal tissue cytoplasmic HSD3B2 staining was stronger in prostate cancers. In 9371 interpretable cancers, HSD3B2 expression was found in 95.5% of cancers and was considered weak in 29...
