Agent orange chemical, dioxin, attacks the mitochondria to cause cancer, says Penn research team
PHILADELPHIA Researchers with the University of Pennsylvania School of Veterinary Medicine have demonstrated the process by which the cancer-causing chemical dioxin attacks the cellular machinery, disrupts normal cellular function and ultimately promotes tumor progression. The team identified f...BRANFORD, Conn., Sept. 27 /PRNewswire/ -- 454 Life Sciences, a Roche company, today reported that researchers from Pennsylvania State University have used the company's Genome Sequencer(TM) FLX system to sequence the entire mitochondrial genomes from 10 individual woolly mammoths. The study, e...
