Zusammenfassung der Projektergebnisse

Biochemical analyses have characterized the BH3-only protein family member NOXA as a “sensitizer” with weak pro-apoptotic activity. Investigations into cancer cell responses to chemotherapeutic agents have however identified NOXA as a pivotal factor mediating the cytotoxic effect of a plethora of anticancer treatments independent of its own pro-apoptotic activity. Accumulating evidence now suggests that tumor cells exert a number of strategies to counteract NOXA function by exploiting diverse cellular regulatory circuits that normally govern NOXA expression during cellular stress responses. Through its distinctive antagonistic specificity for MCL1, NOXA represents a critical factor in the regulation of cell death. The high prevalence of dysregulation of NOXA in cancer, together with observations that reactivation of NOXA under diverse settings restores cytotoxic activity of a number of chemotherapeutics, strongly supports the design and evaluation of therapeutic protocols aiming to restore NOXA function or mimic NOXA action. Knowledge of how NOXA provokes a potent anticancer effect and in combination with which chemotherapeutic agents will greatly advance development of cancer therapeutic regimens. Our data identified another mode in controlling the cytosolic pool of NOXA which can be exploited for the design of novel therapeutic protocols for cancer.
