In addition to antiapoptotic activity, this protein plays a role in cell proliferation and angiogenesis.[14–16] It is expressed in the G2/M phase of the cell cycle at the highest rate to support cell division, whereas its level in the G1 phase is lower.[17] Survivin is detected at insignificant levels in most normal adult tissues, with the exception of the testis, thymus, and placenta; however, it is commonly expressed in human tissues during fetal development.[16,18] Inhibiting apoptosis and increasing cell proliferation, survivin advances tumor growth and progression.[13,19]. The gene discussed is BIRC5; the disease is neoplasm.
