Formation of carbonylated protein derivatives is one of the key signalling pathways in cellular damage and may be regarded as a reliable marker in cellular injury. It allows evaluating both direct effects of reactive oxygen species and indirect interrelations with the secondary by-products of oxidation. The present study was undertaken to investigate the activity of lysosomal cysteine proteinases (cathepsins B and L) in blood serum and the arterial wall in an experimental model of ischaemia and ischaemia-reperfusion injury. To this was added comprehensive assessment of oxidative modification of proteins derived from blood serum and the arterial wall, namely, calculating the area under the curve of the absorption spectrum of the products of protein carbonylation, the proportion of the primary and secondary markers of oxidative stress, as well as the reserve and adaptation potential. The obtained findings were indicative of the development of oxidative stress in the model of ischaemia-reperfusion injury from day 1 to day 7, and in the ischaemia model on day 3 and day 5 in both the vascular wall and blood serum, which was accompanied by activation of cathepsins B and L. Reversible oxidation of proteins was observed on days 3 and 5 in the experimental ischaemia model and on days 1 and 7 in the ischaemia-reperfusion injury model, which was confirmed by the predominance of the primary markers of oxidative stress. Irreversible oxidation of proteins, i. e., the predominance of the secondary markers, was suggestive of the enhancement of oxidative stress, its transition to the late stage, leading to the loss of biological properties of proteins and eventually followed by their aggregation and degradation as seen in the ischaemia-reperfusion injury model on days 3 and 5. Analysing the obtained findings revealed direct correlation between the total area under the curve of oxidative modification of proteins and overall activity of cathepsin L in the ischaemia model: in blood serum on days 3 and 5, in the vascular wall for cathepsins B and L on day 5; in the ischaemia-reperfusion injury model: the activity of cathepsin L in blood serum on day 3, in the vascular wall on day 5 for cathepsins B and L.

D015398 Signal Transduction The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
