The protein kinase C super-family member PKN is regulated by mTOR and influences differentiation during prostate cancer progression.

Prostate 2017 Nov 6;77(15):1452-1467. Epub 2017 Sep 6.

Center for Cell Signaling, University of Virginia, Charlottesville, Virginia.

Background: Phosphoinositide-3 (PI-3) kinase signaling has a pervasive role in cancer. One of the key effectors of PI-3 kinase signaling is AKT, a kinase that promotes growth and survival in a variety of cancers. Genetically engineered mouse models of prostate cancer have shown that AKT signaling is sufficient to induce prostatic epithelial neoplasia (PIN), but insufficient for progression to adenocarcinoma.

ΔNp63α promotes adhesion of metastatic prostate cancer cells to the bone through regulation of CD82.

Oncogene 2017 08 3;36(31):4381-4392. Epub 2017 Apr 3.

Gene Regulation, Stem Cells and Cancer Program, Centre for Genomic Regulation (CRG), The Barcelona Institute of Science and Technology, Barcelona, Spain.

ΔNp63α is a critical mediator of epithelial development and stem cell function in a variety of tissues including the skin and breast, while overexpression of ΔNp63α acts as an oncogene to drive tumor formation and cancer stem cell properties in squamous cell carcinoma. However, with regards to the prostate, while ΔNp63α is expressed in the basal stem cells of the mature gland, during adenocarcinoma development, its expression is lost and its absence is used to clinically diagnose the malignant state. Surprisingly, here we identify a sub-population of bone metastatic prostate cancer cells in the PC3 cell line that express ΔNp63α. Read More

a The School of Biomedical Sciences, Institute of Health and Biomedical Innovation , Queensland University of Technology , Kelvin Grove , Australia.

Head and neck cancer patients often present with advanced metastatic disease resulting in a poor 5-year survival. Therefore, there is a need for non-invasive diagnostic tools that could complement conventional imaging to inform clinicians of patient outcomes and treatment responses. A liquid biopsy addresses this unmet clinical need; a simple peripheral blood draw could provide information about the disseminated disease in terms of circulating tumor cells and circulating tumor DNA.

Department of Experimental Clinical Oncology, Aarhus University Hospital, Denmark.

Background And Purpose: A 15-gene hypoxia profile has previously demonstrated to have both prognostic and predictive impact for hypoxic modification in squamous cell carcinoma of the head and neck. This gene expression profile may also have a prognostic value in other histological cancer types, and could potentially have a function as a universal hypoxia profile. The hypoxia induced upregulation of the included genes, and the validity of the previously used reference genes was established in this study, in a range of different cell lines representing carcinomas of the prostate, colon, and esophagus.

Brachyury is a transcription factor of the T-box family typically expressed in notochord and chordoma. Some studies report brachyury as highly specific for chordoma, whereas others have concluded that brachyury is expressed in many types of common carcinomas by reverse transcription polymerase chain reaction and immunohistochemistry and could be involved in the epithelial-mesenchymal transition and metastatic process. In this study, we immunohistochemically evaluated 5229 different tumors for nuclear brachyury expression using a new rabbit monoclonal antibody and automated immunostaining (Leica Bond Max).

Expression of some selected cytokeratins and Ki67 protein in prostatic tumor: can these be used as tumor markers.

Pan Afr Med J 2015 16;20:46. Epub 2015 Jan 16.

National Hospital Abuja, Nigeria.

Introduction: Diagnosis of prostatic diseases with Immunohistochemistry still faces challenges because of the peculiar histology of the prostate and difference(s) in reactivity of Monoclonal antibodies (MoAb) to benign and malignant changes.

Methods: Thirty (30) archived paraffin embedded tissue samples from primary prostate tumors (15 Benign Prostatic Hyperplasia (BPH) and 15 Cancer of the prostate (CaP)) were sectioned at thickness of 5 µm and confirmed as BPH or CaP. Sections from each sample were stained by Immunohistochemistry using the Streptavidin-biotin method and using CK5/6, CK7, CK8,CK20 and Ki67 antibodies (Zymed Antibody products). Read More

Histologic classification of prostate cancer.

Authors:
Gregor Mikuz

Anal Quant Cytopathol Histpathol 2015 Feb;37(1):39-47

Apart from the typical acinar morphology observed in more than 90% of prostatic adenocarcinomas, a spectrum of morphological variants and prostate cancer subtypes exists. Two nosologically different groups can be distinguished: the variants of conventional acinar cancer and cancers with histological pattern, which are unusual for the prostate. Variants of conventional prostate cancer (pseudohyperplastic, foamy gland, hypernephroid, atrophic, microcystic, with Paneth cell-like changes, with collagenous micronodules, with glomeruloid formations, oncocytic) do not have any known prognostic significance and are graded according to the Gleason system.

Tumour markers are high molecular weight glycoproteins whose interpretation in the presence of chronic renal disease may be disturbed. Apart from the prostate specific antigen, human chorionic gonadotropin and α-fetoprotein, their levels rise with chronic renal failure. For some markers, such as carcinoembryonic antigen, carcinogen antigen (CA) 15-3, cytokeratin fragment 21-1 or calcitonin, a threshold may be defined in a population with chronic renal failure, which may allow their use in cancer surveillance.

An immunohistochemical analysis of a newly developed, mouse monoclonal p40 (BC28) antibody in lung, bladder, skin, breast, prostate, and head and neck cancers.

Arch Pathol Lab Med 2014 Oct 14;138(10):1358-64. Epub 2014 Feb 14.

From the Department of Research and Development, Biocare Medical, LLC, Concord, California (Drs Tacha, Bremer, and Qi); and the Department of Pathology, Mercy General Hospital, Janesville, Wisconsin (Dr Haas).

Context: Immunohistochemistry is important to the pathologist for accurate diagnosis of lung cancer. In recent studies, a rabbit polyclonal p40 (RPp40) antibody demonstrated equivalent staining versus anti-p63 in lung squamous cell carcinoma, and superior specificity because it stains a lesser percentage of lung adenocarcinoma.

Objectives: To develop an anti-p40 mouse monoclonal antibody (MMp40) for immunohistochemistry, and to evaluate its sensitivity and specificity in normal and neoplastic tissues, with emphasis on lung cancer. Read More

Departments of *Pathology †Urology ‡Oncology, The Johns Hopkins Medical Institutions, Baltimore, MD.

High-grade prostate adenocarcinoma can have overlapping morphologic features with high-grade urothelial carcinoma, a critical distinction as treatments differ substantially. Pseudopapillary features have not previously been described in high-grade acinar prostate adenocarcinoma. We reviewed our consult cases (2006 to 2013) for cases of high-grade prostate adenocarcinoma, in which the Gleason score was equal to 5+4=9 or 5+5=10, and the differential diagnosis included high-grade urothelial carcinoma.

p63-expressing cells are the stem cells of developing prostate, bladder, and colorectal epithelia.

Proc Natl Acad Sci U S A 2013 May 25;110(20):8105-10. Epub 2013 Apr 25.

Department of Pathology, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115, USA.

The tumor protein p63 (p63), and more specifically the NH2-terminal truncated (ΔN) p63 isoform, is a marker of basal epithelial cells and is required for normal development of several epithelial tissues, including the bladder and prostate glands. Although p63-expressing cells are proposed to be the stem cells of the developing prostate epithelium and bladder urothelium, cell lineages in these endoderm-derived epithelia remain highly controversial, and rigorous lineage tracing studies are warranted. Here, we generated knock-in mice expressing Cre recombinase (Cre) under the control of the endogenous ΔNp63 promoter. Read More

Department of Hematology and Hematological Laboratory Science, School of Medical Science and Laboratory Medicine, Jiangsu University, Zhenjiang 212013, China.

URI, or RMP, is a RNA polymerase II subunit RPB5-associated protein known to play essential roles in ubiquitination and transcription. Recently, we and others have shown that URI/RMP is also important for progression of hepatocellular carcinoma, ovarian, and prostate cancers. To identify the mechanistic basis of URI/RMP during multiple cellular processes, we investigated URI/RMP expression in a tissue microarray (TMA) containing multiple normal human tissues. Read More
