BIRC5 and neoplasm: Currently, various strategies have been developed to downregulate or block survivin expression to enhance apoptosis and attenuate tumor growth using promoter inhibitors, antisense oligonucleotides, ribozymes, microRNAs, and small interfering RNAs (siRNAs); these molecules target survivin or antagonize the activation and stabilization of survivin by regulating survivin‐suppressing molecules.6, 7
