Scripps Florida awarded $2.5 million to advance development of RNA-based therapeutics

May 04, 2016

JUPITER, FL May 4, 2016 - Scientists from the Florida campus of The Scripps Research Institute (TSRI) have been awarded a $2.5 million grant from the National Institute of General Medical Sciences of the National Institutes of Health to design precision drug candidates that target disease-associated RNAs.

Matthew Disney, a TSRI professor, will be the principal investigator for the new four-year study.

"A major goal of genome sequencing efforts is to develop drug targets that could enable the development of patient-specific therapies," Disney said. "In this project, we are developing quick ways to convert this information into lead drugs by using several novel and transformative technologies we developed. The new grant will keep us moving forward and allow us to tackle many new challenges in the area of precision medicine."

While to date large macromolecules have generally been used to target RNA, small molecules can pass through the blood-brain barrier, a critical factor in the treatment of neurological diseases and cancer that affects the brain.

The Disney lab's untraditional approach has been broadly applicable in developing precision probes to target disease-causing RNA repeat expansions, which cause more than 30 diseases--including Huntington's, which has no cure--affecting millions worldwide.

Disney's successful efforts in identifying various drug-like small molecules that bind to RNA is the result of his lab's broad, bottom-up, computational approach known as Inforna, which can deep mine information against such genome sequences and cellular RNAs.

The new grant will enable Disney and his team to further investigate the manipulation of microRNAs. Discovered only in the 1990s, microRNAs are short molecules that work within virtually all animal and plant cells. Typically, each one functions as a "dimmer switch" for one or more genes, binding to the transcripts of those genes and effectively keeping them from being translated into proteins.

The new grant will also allow Disney to expand development of small molecules that target two miRNAs with a single small molecule and to study the cellular consequences targeting multiple disease pathways using what he calls a "designer poly-pharmacy approach."

The number of the grant is 2R01GM097455-05.

Anthropomorphic
Do animals grieve? Do they have language or consciousness? For a long time, scientists resisted the urge to look for human qualities in animals. This hour, TED speakers explore how that is changing. Guests include biological anthropologist Barbara King, dolphin researcher Denise Herzing, primatologist Frans de Waal, and ecologist Carl Safina.

What makes breakfast, breakfast? Well, according to every movie and TV show we've ever seen, a big glass of orange juice is basically required. But our morning grapefruit might be in danger. Why? Citrus greening, a bacteria carried by a bug, has infected 90% of the citrus groves in Florida. It's coming for your OJ. We'll talk with University of Maryland plant virologist Anne Simon about ways to stop the citrus killer, and with science writer and journalist Maryn McKenna about why throwing antibiotics at the problem is probably not the solution.
