UCLA scientists developed experimental treatment that eradicates acute type of leukemia in mice

A diverse team of scientists from UCLA's Jonsson Comprehensive Cancer Center have developed an experimental treatment that eradicates an acute type of leukemia in mice without any detectable toxic side effects. The drug works by blocking two important metabolic pathways that the leukemia cells need to grow and spread.

Scientists showcase HDL nanotherapy that may provide solution to repeat heart attacks

Up to 30 percent of heart attack patients suffer a new heart attack because cardiologists are unable to control inflammation inside heart arteries - the process that leads to clots rupturing and causing myocardial infarction or stroke.

Study reveals that brain cancer cells resist therapy by dialing down gene mutation targeted by drugs

A team of scientists, led by principal investigator Paul S. Mischel, MD, a member of the Ludwig Institute for Cancer Research and professor in the Department of Pathology at the University of California, San Diego School of Medicine, has found that brain cancer cells resist therapy by dialing down the gene mutation targeted by drugs, then re-amplify that growth-promoting mutation after therapy has stopped.

18F-FDOPA imaging can help distinguish radiation-induced lesions in patients with brain metastases

Imaging with the molecular imaging tracer 18F-FDOPA can help distinguish radiation-induced lesions from new tumor growth in patients who have been treated with radiation for brain metastases, according to new research published in The Journal of Nuclear Medicine. Using this amino acid tracer, researchers found that physicians could accurately differentiate the two types of lesions 83 percent of the time. Progression-free survival could also be predicted through evaluating the 18F-FDOPA imaging results.
