Evaluation of alpha-methylacyl-CoA racemase, metallothionein and prostate specific antigen as prostate cancer prognostic markers.

Current diagnostic techniques are inefficient in distinguishing latent and low-risk forms of prostate cancer from high-risk forms. The present study is focused on determination of putative tumor markers of aggressive high-grade forms of prostate cancer. Potential markers were determined in blood sera of 133 patients (82 cases and 51 controls) and in cell lines (Gleason score 9-derived 22Rv1 and normal tissue derived PNT1A) on mRNA and protein levels.

Caveolin-1 as a potential high-risk prostate cancer biomarker.

Current diagnostic techniques of prostate cancer cannot efficiently distinguish the latent and low-risk forms from the high-risk significant forms of prostate cancer. Caveolin-1 (Cav-1), except other functions, plays an important role in cell transformation and the process of tumorigenesis. Furthermore, Cav-1 is involved in metastatic processes.

[Molecular mechanisms of zinc in prostate cancer].

In many developed countries, prostate cancer is the most common male tumour disease. The high incidence and mortality requires early diagnosis, differentiation of aggressive, highly malignant forms from clinically silent forms and understanding of the pathogenesis with its typical metabolic aberrancies (if any) in order to develop new targeted therapies. Prostate cells (including prostate cancer cells) are unique in their relation to zinc ions.

Androgen receptor in prostate carcinoma: immunohistochemical and ligand saturation analyses.

Status of androgen receptor (AR) in prostate carcinoma is biologically important. Therefore, more methods assessing AR abnormalities are warranted. Immunohistochemical (IHC) and ligand saturation (LSA) assays were not compared in details.

[Hereditary pheochromocytoma--a family affected by von Hippel-Lindau disease].

The authors present a case of a 37 year old male (proband) with a 13 year history of progressive sight impairment leading to blindness and a 4 year history of a mild hypertension. He was incidentally found to have large adrenal tumors after an ultrasound kidney examination. The tumors were confirmed with CT scan and magnetic resonance imaging.
