First (and massive) whole-genome study of IBD in African Americans

In African Americans, the genetic risk landscape for inflammatory bowel disease (IBD) is very different from that of people with European ancestry, according to results of the first whole-genome study of IBD in African Americans. The authors say that future clinical research on IBD needs to take ancestry into account. Findings of the multi-center study, which analyzed the whole genomes of more than 1,700 affected individuals with Crohn’s disease and ulcerative colitis and more than Read more

Emory researchers SNARE new Alzheimer’s targets

Diving deep into Alzheimer’s data sets, a recent Emory Brain Health Center paper in Nature Genetics spots several new potential therapeutic targets, only one of which had been previous linked to Alzheimer’s. The Emory analysis was highlighted by the Alzheimer’s site Alzforum, gathering several positive comments from other researchers. Thomas Wingo, MD Lead author Thomas Wingo and his team -- wife Aliza Wingo is first author – identified the targets by taking a new approach: tracing Read more


The healing spice: curcumin

A recent article in Chemical & Engineering News describes the promising properties of curcumin, a compound derived from turmeric, in models of Alzheimer’s disease.

Curcumin is a component of turmeric

In addition to contributing to curry dishes’ yellow color and pungent flavor, curcumin has been a medicine in India for thousands of years. Doctors practicing traditional Hindu medicine admire turmeric’s active ingredient for its anti-inflammatory properties and have used it to treat patients for ailments including digestive disorders and joint pain.

Only in the 1970s did Western researchers catch up with Eastern practices and confirm curcumin’s anti-inflammatory properties in the laboratory. Scientists also eventually determined that the polyphenolic compound is an antioxidant and has chemotherapeutic activity.

Several research groups at Emory are investigating curcumin-related compounds.
Dermatologist Jack Arbiser has been interested in curcumin’s antiangiogenic (inhibiting blood vessel growth) properties for several years and reports that he is studying how the compound is metabolized. Chemist Dennis Liotta and his colleagues have identified relatives of curcumin that are more soluble, and thus could be more easily taken up by the body. In particular, chemist James Snyder has been a key driver in designing and synthesizing curcumin-related compounds used by several investigators at Emory and elsewhere (see figure):

Psychiatrists Thaddeus Pace and Andrew Miller have been testing whether  curcumin relatives may have useful properties with depression. Specifically, the curcumin-related compounds may have the ability to interfere with the connection (YouTube video) between inflammation and depression.

Winship Cancer Institute researcher Mamoru Shoji has been exploring how to target curcumin compounds to tumor-associated endothelial cells by linking them to a clotting factor. In the Department of Gynecology and Obstetrics, Friedrich Wieser is examining whether curcumin compounds can be helpful with endometriosis.
