Mouse version of 3q29 deletion: insights into schizophrenia/ASD pathways

Emory researchers see investigating 3q29 deletion as a way of unraveling schizophrenia’s biological and genetic Read more

B cells off the rails early in lupus

Emory scientists could discern that in people with SLE, signals driving expansion and activation are present at an earlier stage of B cell differentiation than previously Read more

Head to head narcolepsy/hypersomnia study

At the sleep research meeting in San Antonio this year, there were signs of an impending pharmaceutical arms race in the realm of narcolepsy. The big fish in a small pond, Jazz Pharmaceuticals, was preparing to market its recently FDA-approved medication: Sunosi/solriamfetol. Startup Harmony Biosciences was close behind with pitolisant, already approved in Europe. On the horizon are experimental drugs designed to more precisely target the neuropeptide deficiency in people with classic narcolepsy type 1 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.

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.
