Role of DNA damage response signalling in induction and maintenance of cellular senescence
Pešina, František ; Hodný, Zdeněk (advisor) ; Janoštiak, Radoslav (referee)
Cellular senescence is a state of permanent growth arrest. It is induced by many stimuli, including telomere shortening, DNA damage, oncogene hyperstimulation, chromatin perturbation and various stresses by which are cells affected. Researches showed central role of two pathways in induction and maintenance of this state. These are the p53/21 and p16/RB. The extent and dynamics of their activation by various stimuli is different. Slightly different is also their function in induction and maintenance of senescence. These differences are depicted and compared in this work.
