Thymidine kinase 1 (TK1), deoxycytidine kinase (dCK), and thymidine phosphorylase (dThdPase) are the enzymes involved in pyrimidine and purine metabolism; TK1 activity is correlated with growth processes, and dThdPase is involved in the mechanisms of angiogenesis. The increased activities of TK1, dCK and dThdPase or the increased expression of genes for theses enzymes have been found in different tumors. The aim of the study was to estimate the expression of mRNA, specific for...

Low-T3 syndrome (euthyroid sick syndrome) develops in critically ill patients. Due to the catabolic state, accompanying critical illnesses, enhanced oxidative damage to macromolecules is expected to occur in subjects suffering from the low-T3 syndrome.The study aimed at evaluating the level of lipid peroxidation products in blood serum, collected from critically ill patients with the low-T3 syndrome and at estimating the ...

Increased blood activities of some enzymes, participating in pyrimidine and purine metabolism, were found in blood fractions of patients suffering from autoimmunological thyroid diseases (AITD), i.e., Graves' or Hashimoto's disease. The aim of the study was to estimate the expression of RNA specific for the enzymes in question. An approval of the Ethical Committee of the Medical University of Lodz has been obtained. The expression of the following enzymes was estimated in huma...
