Survivin as a Potential Target for Cancer Therapy.

In 1997 for the first time, survivin was described by Amborsini et al. as an anti-apoptotic protein. Subsequent studies revealed that survivin is a multifunctional protein that plays critical roles in several crucial cell processes such as apoptosis, cell cycle, chromosome movement, mitosis and cellular stress responses. Moreover, it's over- expression in cancer cells versus normal cells is associated with chemotherapy resistance, increased tumor recurrence, and shorter patient survival. All of these features make survivin a promising target for cancer therapy. Here, we review the potential characteristics of survivin as a tumor marker.
