Semenkovich1,2,* 1Department of Medicine 2Department of Cell Biology and Physiology. Chloroquine was administered by two intraperitoneal injections of 59.4 μg per 17 g of body weight, 24 hours and 4 hours before irradiation.. When the Kastan lab discovered that chloroquine can activate ATM, it provided a potential treatment intervention, the success of which is reported in this paper Treatment of ATM +/+ apoE −/− mice with low-dose chloroquine, an ATM activator, decreased atherosclerosis. Nov 01, 2012 · Chloroquine administration before radiation did not affect the survival of ATM null mice (p = 0.86). Jan 02, 2008 · Chloroquine-induced cell death in primary MEFs and human colorectal cancer cells was dependent upon p53, but not upon the p53 modulators Atm or Arf. Chloroquine-induced cell death in primary MEFs and human colorectal cancer cells was dependent upon p53, but not upon the p53 modulators Atm or Arf. • Chloroquine also activates glycogen synthase that is downstream of Akt in muscle cells.

The effect of Chloroquine may also be related to the formation of a toxic heme-Chloroquine …. Chloroquine is a 4-aminoquinoline with antimalarial, anti-inflammatory, and potential chemosensitization and radiosensitization activities. 4 Chloroquine and resveratrol stimulate phosphorylation of AMPK and chloroquine stimulates phosphorylation of Akt when ATM is inhibited. To cope with this problem, these cells have evolved an elaborate network of sensor, transducer, and effector chloroquine atm kastan proteins that coordinate cell-cycle progression with the repair of the initiating DNA lesion. Cell Metabolism, 2006. Hydroxychloroquine and chloroquine are antimalarial drugs commonly used for the treatment of rheumatic diseases. This observation led to studies in the Semenkovich lab showing the importance of ATM in metabolic syndrome. Both ATM- and p53-null mice have been shown to have increased atherosclerosis (9, 10, 22, 23), and activation of ATM with chloroquine decreases atherosclerotic burden in mice .
