Evasion of apoptosis (programmed cell death) is a characteristic feature of human cancers including childhood malignancies. Since cytotoxic therapies such as chemotherapy or radiotherapy trigger apoptosis as a primary mechanism of action, resistance to apoptosis can also lead to treatment resistance. Studies on apoptosis pathways in childhood malignancies yielded a series of key molecules that can now be exploited as molecular targets for the development of targeted therapies. This strategy is anticipated to open novel perspectives for more effective treatment options for children with cancer. 相似文献

Livin/ML-IAP as a new target for cancer treatment 总被引:21,自引:0,他引:21
Livin is a member of the inhibitors of apoptosis protein (IAP) gene family, which encodes negative regulatory proteins that prevent cell apoptosis. Livin is selectively expressed in the most common human neoplasms and appears to be involved in tumor cell resistance to chemotherapeutic agents. Several studies in vitro and in vivo have demonstrated that down-regulation of Livin expression increases the apoptotic rate, reduces tumor growth potential and sensitized tumor cells to chemotherapeutic drugs. This review will focus on the role of this protein during cancer development and progression and will demonstrate possible targets for cancer therapy. 相似文献
