Thrombin induced tumour growth - pharmacological control
Research article published in Hamostaseologie (2007)
Abstract
The central enzyme of blood coagulation, the serine proteinase thrombin, is capable to modify the growth of tumour cells by interaction with protease activated receptors 1 and 4 of the tumour cells. Thrombin is permanently available in tumour micro environment; meizothrombin is generated from prothrombin at a tumour specific activation complex and can influence tumour cell growth via PAR-1 and 7-transdomain protein receptor signalling pathway, too. PEG-coupled direct thrombin inhibitors that possess special pharmacokinetic characteristics and that have been designed for long lasting efficacy in extracellular space, control serine proteinase activity in tumour micro environment and therefore they own a high potential anti-tumour efficacy. In xenographic tumour models this new substance class has shown a significant carcinostatic effect.

Почему это важно для гирудотерапии
This abstract examines how thrombin modifies tumor cell growth through protease-activated receptors (PAR-1 and PAR-4) and tests PEG-coupled direct thrombin inhibitors as a means of controlling thrombin activity in the tumor microenvironment, reporting significant carcinostatic effects in xenographic tumor models. This work is tangentially relevant to the broader pharmacology of thrombin inhibition. However, the abstract makes no mention of hirudin, leeches, or any leech-derived compounds. The study involves a PEG-coupled inhibitor class, not hirudin or related molecules, so the connection to hirudotherapy or the leech secretome is not established by this abstract.
