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

Promising probe for detecting recurrent prostate cancer

Part of the new Winship magazine feature on prostate cancer focuses on a PET imaging probe called FACBC, which was developed by radiologists at Emory. 18F-FACBC (anti-1-amino-3-[18F]fluorocyclobutane-1-carboxylic acid, also called “fluciclovine”) has a lengthening track record in detecting recurrent prostate cancer.

Structure of FACBC, from patent application.

Usually in PET imaging, radioactive glucose is injected into the body, and since cancer cells have a sweet tooth, they take up a lot of the radioactive tracer. But plenty of the tracer also appears in the urine, complicating prostate cancer detection efforts, since the prostate is so close to the bladder. In contrast, FACBC is readily taken up by prostate cancer cells, but doesn’t appear as much in urine.

Because of space considerations, we did not include David Schuster’s description of how FACBC’s utility in prostate was first discovered. Several years ago, he and Mark Goodman had begun investigating the probe’s potential in imaging brain tumors and kidney tumors, and used it with a patient with a large renal mass and many enlarged lymph nodes, as described in the radiology newsletter Aunt Minnie.
