Sažetak

Endogenous transmethylation processes proceed via formaldehyde. Endogenous formaldehyde can
be found in special bounded forms in animal tissues. The aim was to find non-invasive methods to help establish
an early diagnosis of prostate cancer processes, and to search for a reliable examination repertoire to predict
metastasis based on genomic hypomethylation that can be found in tumors. Fifty-eight age-matched patients
suffering from prostate cancer and 26 healthy volunteers were enrolled in the study. Biochip technique
was applied to quantify serum interleukins and growth factors. OPCL method served to determine mobilized
formaldehyde, and fluorometric methods were applied to measure Zn- and free protoporphyrin concentrations
in erythrocytes. Spectrophotometric measurements were carried out to evaluate redox homeostasis in
plasma. There were no significant differences in most measured laboratory and immune parameters at different
early stages of prostate cancer; at the same time, erythrocyte parameters, especially immobilized formaldehyde
determination, were promising. The authors assume that hypomethylation detection in erythrocytes
might become a predictive factor in the diagnostic panel in the near future. (doi: 10.5562/cca1748)
