Tug of War between Survival and Death: Exploring ATM Function in Cancer

Abstract: Ataxia-telangiectasia mutated (ATM) kinase is a one of the main guardian of genome stability and plays a central role in the DNA damage response (DDR). The deregulation of these pathways is strongly linked to cancer initiation and progression as well as to the development of therapeutic approaches. These observations, along with reports that identify ATM loss of function as an event that may promote tumor initiation and progression, point to ATM as a bona fide tumor suppressor. The identification of ATM as a p… Show more

“…ATM transduces a DSB repair signal to downstream effector machinery by phosphorylating critical protein substrates ( Hu et al , 2010 ). ATM also has a role in cell cycle arrest, apoptosis and senescence, in order to prevent genomic instability ( Stagni et al , 2014 ).…”

“…Knowing if a patient carries a germline ATM mutation may help to guide treatment decisions (Stagni et al, 2014). Those with a germline ATM mutation being treated for ovarian cancer may have a better response to platinum-based therapy or PARP inhibitors, according to a few small retrospective reviews (Gilardini Montani et al, 2013;Pennington et al, 2014).…”
