Title of diploma thesis: Cell senescence in aging, cell stress, and chemoresistance The process of biological aging is connected with a loss of tissue function leading to the various pathologies, including cardiovascular diseases and cancer. Cellular senescence, the phenomenon characterized by permanent cell cycle arrest triggered by endogenous or exogenous stress plays a significant role in age-related metabolic diseases development. Senescent endothelial cells have been found in atherosclerotic plaque and due to the inflammation-inducing factors participate to its progression. Nevertheless, by triggering antiproliferative reaction, senescence may also have a potential as a cancer suppressor. The aim of this work was to establish assay determining senescence with different origins and subsequently, to analyse compounds with a potential to reduce H2O2-induced senescence as well as factors, which may be altered in the senescent phenotype. Senescence-associated β- galactosidase (SA-β-gal) assay in primary human endothelial cells revealed the senescence-inhibiting ability of statins and curcumin in contrast...
