Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more

Reddit as window into opioid withdrawal strategies

Drug abuse researchers are using the social media site Reddit as a window into the experiences of people living with opioid addiction. Abeed Sarker in Emory's Department of Biomedical Informatics has a paper in Clinical Toxicology focusing on the phenomenon of “precipitated withdrawal,” in collaboration with emergency medicine specialists from Penn, Rutgers and Mt Sinai. Precipitated withdrawal is a more intense form of withdrawal that can occur when someone who was using opioids starts medication-assisted treatment Read more

CROI: HIV cure report and ongoing research

The big news out of CROI (Conference on Retroviruses and Opportunistic Infections) was a report of a third person being cured of HIV infection, this time using umbilical cord blood for a hematopoetic stem cell transplant. Emory’s Carlos del Rio gave a nice overview of the achievement for NPR this morning. As del Rio explains, the field of HIV cure research took off over the last decade after Timothy Brown, known as “the Berlin patient,” 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.
