Warren symposium follows legacy of geneticist giant

If we want to understand how the brain creates memories, and how genetic disorders distort the brain’s machinery, then the fragile X gene is an ideal place to start. That’s why the Stephen T. Warren Memorial Symposium, taking place November 28-29 at Emory, will be a significant event for those interested in neuroscience and genetics. Stephen T. Warren, 1953-2021 Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more

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

Stop the blob!

For your viewing pleasure, we have two videos, courtesy of Winship Cancer Institute’s Adam Marcus. He and his colleagues are investigating whether Withania somnifera, a root used in Indian traditional medicine, could be a source for drugs that inhibit breast cancer invasion and metastasis. Metastasis occurs when cells from a primary tumor migrate to a new location and invade the tissues at the new location.

The first video, the blob that grows, shows MCF10a mammary Ray Ban outlet epithelial cells undergoing epithelial-mesenchymal transition (EMT) in response to TGF-beta. This is a laboratory model for understanding breast cancer invasion and metastasis.

The second shows what happens when the same cells are treated with an extract from Withania somnifera. The blob doesn’t expand in such a threatening way anymore! The results were recently published in PLOS One.
