Beyond the amyloid hypothesis: proteins that indicate cognitive stability

If you’re wondering where Alzheimer’s research might be headed after the latest large-scale failure of a clinical trial based on the “amyloid hypothesis,” check this Read more

Mother's milk is OK, even for the in-between babies

“Stop feeding him milk right away – just to be safe” was not what a new mother wanted to hear. The call came several days after Tamara Caspary gave birth to fraternal twins, a boy and a girl. She and husband David Katz were in the period of wonder and panic, both recovering and figuring out how to care for them. “A nurse called to ask how my son was doing,” says Caspary, a developmental Read more

Focus on mitochondria in schizophrenia research

Despite advances in genomics in recent years, schizophrenia remains one of the most complex challenges of both genetics and neuroscience. The chromosomal abnormality 22q11 deletion syndrome, also known as DiGeorge syndrome, offers a way in, since it is one of the strongest genetic risk factors for schizophrenia. Out of dozens of genes within the 22q11 deletion, several encode proteins found in mitochondria. A team of Emory scientists, led by cell biologist Victor Faundez, recently analyzed Read more

American Society for Cell Biology

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.
