Abstract:
Significant improvements in the knowledge of cancer biology have permitted the development of new molecular targeted therapies. Meanwhile, a better understanding of the physiology of various non-cancerous diseases has allowed developing these agents in other areas. This review intends to illustrate these perspectives through examples corresponding to different strategies of molecular-targeted therapies : use of a monoclonal antibody binding a receptor (rituximab and rheumatoid arthritis) or a ligand (bevacizumab and age-related macular degeneration), tyrosine kinase inhibitor (imatinib and systemic sclerosis) or inhibitor of cytoplasmic signal transduction pathways (immunosuppressive and antiproliferative effects of mammalian target of rapamycin [mTOR] inhibitors). Clinical results can draw today what could become molecular medicine of tomorrow.
Insights

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
