Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

RNAi therapy shuts down gene critical to RSV, prevents virus replication

John DeVincenzo, MD, professor and researcher in the Departments of Pediatrics and Molecular Sciences at the University of Tennessee Health Science Center (UTHSC), has proven for the first time that a totally new concept in drug design can be used to treat human disease. Dr. DeVincenzo, who also serves as a children's infectious diseases specialist at Le Bonheur Children's Hospital, conducted his study at the Children's Foundation Research Center, a UT Health Science Center partner located at Le Bonheur.

Study demonstrates protection against Ebola infection in nonhuman primates using RNAi

Scientists using tiny particles of genetic material to interfere in the replication process of the deadly Ebola virus have successfully prevented monkeys exposed to that virus from dying of hemorrhagic fever. The proof-of-concept study, published in this week's issue of The Lancet, suggests that such protection also should be possible in humans.

Regulus Therapeutics obtains rights to intellectual property covering methods for modulating microRNA-21

Regulus Therapeutics Inc. announced today that it has obtained exclusive rights from the University of Wuerzburg to intellectual property covering methods for modulating microRNA-21. Regulus scientists and collaborators have shown that microRNA-21, (miR-21), is dysregulated in mouse models of cardiac disease and fibrosis, and that antagonizing miR-21 with therapeutic oligonucleotides targeting miR-21 inhibits fibrosis and attenuates cardiac function in such models. Regulus is currently developing a microRNA therapeutic targeting miR-21 as an anti-fibrotic therapy.
