The role of caspase 2 in apoptosis induction in tumor cells.
 Schmiedlová, Martina ; Kovář, Jan (advisor) ; Horníková, Lenka (referee)
Within the cell, caspase-2 probably fulfills several functions. Caspase-2 can be involved in apoptosis induction, DNA repair as well as cell cycle regulation. Caspase-2 has the character of initiator and also executioner caspase. A stimulus for caspase 2 activation can be oxidative stress or DNA damage. Caspase-2 is activated by cleavadge during an interaction with protein complexes. One of protein complexes,i.e. PIDDosome, is made of protein PIDD, RAIDD and pro-caspase-2. Withine the PIDDosome, caspase-2 is activated. Activated caspase-2 occures in a short S form and in long L form. L form of caspase-2 has proapoptotic effects and S form of caspase-2 has antiapoptotic effects. Caspase-2S has been only detected on mRNA level but not on protein level. The main role of caspase-2L is apoptosis induction in normal and tumor cells. Caspase-2 in tumour cells is activated by extrinstic as well as intristic apoptotic pathway. Apoptosis induction by caspase-2 is for example studied in connection with breast cancer treatment with taxanes. Caspase-2 ability of apoptosis induction in cancer cells independently of p53 protein is employed in cancer treatment including overcoming the resistance to apoptosis induction which is based on loosing p53 activity. Caspase-2 is involved in apoptosis induction by different...
