The cancer cell proteome and its changes after anti-cancer drug treatment
Tylečková, Jiřina
Cancers represent a group of unprecedented heterogeneous diseases and currently available anti-cancer therapies provide highly variable efficacy with unsatisfactory cure rates. A wide range of proteomic technologies are being used in quest for newer approaches which could significantly contribute to the discovery and development of selective and specific cancer biomarkers for monitoring the disease state and anti-cancer therapy success. Taking into consideration the above aspects, this research was undertaken to study cancer cell proteomes and their changes after anti-cancer treatment with specific focus on: (a) response to conventional anthracycline/anthracenedione drugs with respect to their different clinical efficacy and (b) identification of novel targets for therapy in cancer cells resistant to biological drugs such as inhibitors of (b1) cyclin-dependent kinases and (b2) Aurora kinases. This study identified several interesting key aspects related to the effects of daunorubicin, doxorubicin and mitoxantrone. With the main focus on early time intervals when the influence of apoptosis is minimised, changes common for all three drugs belonging mainly to metabolic and cellular processes were observed. More importantly, significant changes in proteins involved in the generation of precursor...
