The ataxia telangiectasia mutated (ATM) checkpoint is the central surveillance system that maintains genome integrity. We found that in the context of childhood sarcoma, mammalian target of rapamycin (mTOR) signaling suppresses ATM by up-regulating miRNAs targeting ATM. Pharmacological inhibition or genetic down-regulation of the mTOR pathway resulted in increase of ATM mRNA and protein both in...
ATM is becoming a widely used technology as a backbone for connecting data networks. An important consideration when analyzing the performance of data traffic over switched networks such as ATM is the routing scheme utilized. The IP layer traditionally handles all routing processes in TCP/IP networks. For ATM, OPNET contains standard models that map IP packet traffic to ATM virtual circuits. Ho...

: روش gmres یک روش تکراری برای حل دستگاه معادلات خطی ax=b است. به علت هزینه متعامد سازی یا محدود بودن ذخیره سازی ممکن است نیاز به شروع مجدد باشد. در حالت کلی، شروع مجدد موجب کند شدن همگرایی روش gmres می گردد. در این پایان نامه روش هایی مورد بررسی قرار می گیرند که همگرایی روش gmres با شروع مجدد را بهبود می بخشند. این روش ها، در زمان شروع مجدد، تعدادی از بردارهای ریتز همساز را حفظ می کنند و با کا...

Oncogenes can induce p53 through a signaling pathway involving p19/Arf. It was recently proposed that oncogenes can also induce DNA damage, and this can induce p53 through the Atm DNA damage pathway. To assess the relative roles of Atm, Arf, and p53 in the suppression of Ras-driven tumors, we examined susceptibility to skin carcinogenesis in 7,12-dimethylbenz(a)anthracene/12-O-tetradecanoylphor...
There are conflicting reports about the involvement of single nucleotide polymorphisms (SNPs) of the ataxia telangiectasia mutated (ATM) gene with cancer, and the consequences of these SNPs for ATM function remain unclear. We therefore sought to identify SNPs of the ATM gene in pediatric Hodgkin disease (HD) and to analyze ATM function in cells from patients with these SNPs. We have identified ...
BACKGROUND Cell senescence is involved in the process of organ damage and repair; however, the underlying molecular mechanism needs to be further explored. METHODS AND RESULTS Senescence-related genes (ie, p21, p53, and ataxia telangiectasia mutated [ATM]) were shown to be elevated after myocardial infarction (MI) in both mouse and human hearts. Ten- to 12-week-old male wild-type littermates ...
The ATM protein kinase mediates a rapid induction of cellular responses to DNA double strand breaks (DSBs). ATM kinase activity is enhanced immediately after exposure of cells to DSB-inducing agents, but no changes in its amount or subcellular location following that activation have been reported. We speculated that some of the ATM molecules associate with sites of DSBs, while the rest of the n...
Unsupervised domain adaptation addresses the problem of transferring knowledge from a well-labeled source to an unlabeled target where two domains have distinctive data distributions. Thus, essence is mitigate distribution divergence between domains. The state-of-the-art methods practice this very idea by either conducting adversarial training or minimizing metric which defines gaps. In paper, ...
