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

Another side to cancer immunotherapy? Emory scientists investigate intratumoral B cells

B cells represent the other major arm of the adaptive immune system, besides T cells, and could offer opportunities for new treatments against some kinds of 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

Chasing invasive cancer cells and more at #ASCB15

Earlier today, we posted a notice on Eurekalert for a Sunday, December 13 presentation by graduate student Jessica Konen at the American Society for Cell Biology meeting in San Diego.

Her research, performed with Adam Marcus at Winship Cancer Institute, was the topic of a video that recently won first prize in a contest sponsored by the Association of American Medical Colleges. This was our video team’s first use of the “fast hand on whiteboard” effect, and a lot of fun to make. The video’s strength grows out of the footage Konen and Marcus have of cancer cells migrating in culture. Check it out, if you haven’t already.

Poster presentations at the 2015 ASCB meeting can be found by searching this PDF. A few Emory-centric highlights:

*Chelsey Ruppersburg and Criss Hartzell’s work on the “nimbus”, a torus-shaped structure enriched in proteins needed to build the cell’s primary cilium

*Anita Corbett on how Emory students have a strong record of attaining their own NIH research funding

*Additional work by Adam Marcus’ lab on the tumor suppressor gene LKB1 and how its loss drives lung cancer cells to take on a “unique amoeboid morphology”

*Research from David Katz’s lab on the “epigenetic eraser” LSD1 (lysine-specific demethylase) and its function in neurons and neurodegeneration Read more

Cancer metastasis: isolating invasive cells with a color change

The capacity of cancer cells to spread throughout the body and metastasize (invade new tissues) makes them deadly. What makes metastatic cells different?

Scientists at Winship Cancer Institute of Emory University have developed a technique for isolating individual cells that display invasive behavior out of a large group in culture by changing their color.
