Engineered “stealth bomber” virus could be new weapon against metastatic cancer

Researchers at Emory and Case Western Reserve have re-engineered a cancer-killing virus, so that it is not easily caught by parts of the immune system. Read more

Don’t go slippery on me, tRNA

RNA can both carry genetic information and catalyze chemical reactions, but it’s too wobbly to accurately read the genetic code by itself. Enzymatic modifications of transfer RNAs – the adaptors that implement the genetic code by connecting messenger RNA to protein – are important to stiffen and constrain their interactions. Biochemist Christine Dunham’s lab has a recent paper in eLife showing a modification on a proline tRNA prevents the tRNA and mRNA from slipping out Read more

Improving measurement of pesticides in breast milk

Little is known about the exposure of infants to pesticides, despite their vulnerability and evidence of widespread dietary exposure among older children and adults. A study led by Emory Rollins School of Public Health researchers P. Barry Ryan, PhD, and Anne Riederer, ScD, seeks to improve methods for measuring pesticides in breast milk and infant formula.

“We really don’t know about how babies are exposed to pesticides in their everyday life,” says Riederer, assistant research professor, Department of Environmental and Occupational Health. “There are very few published studies on this topic, and we’d like to be one of the groups that actually publishes an analytical method that can be used by researchers in any country to be able to detect these different types of pesticides in breast milk.”

Although the breast milk method will be pilot tested on samples collected from a birth cohort in Thailand, it will have broad applications for the U.S. population. Because these pesticides are widely distributed in the food supply, all U.S. infants are potentially exposed.
