Precision medicine with multiple myeloma

“Precision medicine” is an anti-cancer treatment strategy in which doctors use genetic or other tests to identify vulnerabilities in an individual’s cancer subtype. Winship Cancer Institute researchers have been figuring out how to apply this strategy to multiple myeloma, with respect to one promising drug called venetoclax, in a way that can benefit the most patients. Known commercially as Venclexta, venetoclax is already FDA-approved for some forms of leukemia and lymphoma. Researchers had observed that multiple Read more

Promiscuous protein droplets regulate immune gene activity

Biochemists at Emory are achieving insights into how an important regulator of the immune system switches its function, based on its orientation and local environment. New research demonstrates that the glucocorticoid receptor (or GR) forms droplets or “condensates” that change form, depending on its available partners. The inside of a cell is like a crowded nightclub or party, with enzymes and other proteins searching out prospective partners. The GR is particularly well-connected and promiscuous, and Read more

Strengthening SARS-CoV-2 genomic surveillance: support from CDC, private foundations

As part of an effort to strengthen genomic surveillance for emerging strains of SARS-CoV-2, the Centers for Disease Control and Prevention (CDC) has awarded a contract to Emory University researchers to characterize viral variants circulating in Georgia.

The two-year contract is part of the SPHERES (SARS-CoV-2 Sequencing for Public Health Emergency Response, Epidemiology and Surveillance) initiative, with roughly $620,000 in total costs. The principal investigator is Anne Piantadosi, MD, PhD, assistant professor of pathology and laboratory medicine, with co-investigator Mehul Suthar, PhD, assistant professor of pediatrics (infectious diseases).

Both Piantadosi and Suthar are affiliated with Emory University School of Medicine and Emory Vaccine Center. Additional Emory partners include assistant professor of medicine Ahmed Babiker, MBBS, assistant professor of medicine Jesse Waggoner, MD and assistant professor of biology Katia Koelle, PhD.

“We are analyzing SARS-CoV-2 genomes from patients in Georgia to understand the timing and source of virus introduction into our community,” Piantadosi says. “We want to know whether there have been population-level changes in the rates of viral spread, and whether there are associations between viral genotype, viral phenotype in vitro, and clinical phenotype or clinical outcome.”
