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

High-contrast brain tumor imaging

This month’s intriguing images come from radiation oncologist Ian Crocker and colleagues. Each one shows a patient with a glioblastoma, an aggressive brain tumor. The patient’s brain was scanned in two ways: on the left, MRI (magnetic resonance imaging) and on the right, PET (positron emission tomography), using a probe developed at Emory. We can see that the tumor’s PET signal is more distinct than the tumor’s appearance on MRI.

Since the 1990s, Mark Goodman, John Votaw and colleagues at Emory’s Center for Systems Imaging have been developing the probe FACBC (fluoro-1-amino-3-cyclobutyl carboxylic acid) as a probe for the detection of tumors.
