Аннотация
We analyzed the dynamics of the expression of transcription factors, VEGF and its receptor VEGFR2, serine-threonine protein kinase mTOR and activity of proteasome and calpain in patients with metastatic renal cancer during therapy with tyrosine kinase inhibitor Votrient and mTOR blocker Afinitor. The expression of hypoxic nuclear factor HIF-1α in the tumor tissue decreased during therapy with the target preparations. The decrease of VEGF and its receptor VEGFR2 was observed only in patients treated with mTOR inhibitor. The increase in calpain activity in the tumor tissue was observed in both groups. These findings extend our understanding of the mechanism of action of target anticancer preparations as allow considering the studied markers as predictors in choosing optimal therapy.
