The Autophagy-Cancer Connection
03/11/2009
In an upcoming G&D paper, Dr. Masashi Narita (Cancer Research UK) and colleagues functionally link autophagy and cellular senescence. Using a model of oncogenic ras-induced senescence, the authors show that senescence activates autophagy in human fibroblast cells. Dr. Narita and colleagues demonstrate that over-expression of an autophagy inducer also induces senescence, while the inhibition of autophagy delays senescence. Future work will be aimed at delineating the precise role of autophagy in tumorigenesis, but this paper firmly establishes a key role for autophagy in senescence.
