Doxorubicin and liposomal doxorubicin induce senescence by enhancing nuclear factor kappa B and mitochondrial membrane potential

摘要

Aims: Senescence is a state ensuing aging to eliminate age-associated damage with an irreversible cell-cycle arrest mechanism, which is historically believed to be one of the tumor responses to therapy. Doxorubicin as an anti-cancer drug has been used in cancer treatment for a long time. Liposomal doxorubicin (Ldox) is a liposomal formulation of doxorubicin, which increases the doxorubicin permanency. The aim of this study was to examine the toxicity of these two formulations by comparing them in terms of their ability to induce cellular senescence.
