  • Research summary

    The study will investigate whether direct oral anticoagulant (DOAC) drugs, which inhibit activated clotting factors, can have anti-inflammatory effects on endothelial cells by inhibiting activation of protease-activated receptors (PAR-1 and PAR-2). This is turn could prevent endothelial cell apoptosis and vascular damage, which can contribute to the formation of blood clots. Microvesicles isolated from blood samples of patients with kidney cancer (or renal cell carcinoma, RCC) will be applied to endothelial cells in the presence of DOACs and the effect on the induction of apoptosis will be measured.

    A second component of the study will focus on the ability of RCC to invade the venous system, resulting in an extension of the tumour called a ‘tumour thrombus’. Diagnostic biopsy samples from RCC patients will be examine for potential changes in levels of markers of endothelial cell damage and/or activation that might explain a role for this tumour thrombus in causing local inflammation.
