‘Morrbid’ RNA Could Be Key to Asthma Treatment

Researchers have discovered a potential therapeutic target for inflammatory disorders that are characterized by abnormal myeloid cell lifespan, such as asthma, Churg-Strauss syndrome, and hypereosinophilic syndrome. Investigators including Adam Williams of UConn Health and The Jackson Laboratory named the novel long non-coding RNA ‘Morrbid’ (Myeloid RNA Regulator of Bim-Induced Death). They discovered that Morrbid tightly controls how long circulating myeloid cells live — which is key to maintaining the balance between fighting infection and exacerbating inflammation — by overriding a signaling mechanism that prevents premature immune cell death. In mice, deleting the gene helped protect them against inflammation and immunopathology. The findings were published online in Nature, Aug. 15, 2016.


Parents Living Longer is Good News for Offspring, Study Says

A new study led by the University of Exeter and co-authored by the UConn Center on Aging, among other international contributors, shows that how long a person’s parents live can help predict how long the offspring will live, and how healthy the child will be as he or she ages. The study of 186,000 participants, aged 55 to 73 years and followed for up to eight years, is the largest of its kind. It found that a person’s chance of survival increased by 17 percent for each decade that at least one parent lived beyond age 70, and that those with longer-lived parents had lower rates of heart disease and other circulatory conditions, as well as cancer. The study was published in the Journal of the American College of Cardiology, Aug. 15, 2016.


PRP Limits Ill Effects of Osteoarthritis Treatment

Giving platelet-rich plasma (PRP) to patients undergoing treatment for osteoarthritis may limit the negative effects of the drugs used to manage their symptoms, according to a new study led by Dr. Augustus Mazzocca, director of the UConn Musculoskeletal Institute, and the University of Pittsburgh Medical Center. Osteoarthritis is the most common chronic condition of the joints, causing pain, stiffness, and swelling in approximately 27 million Americans. Powerful anti-inflammatory medicines and local anesthetics relieve pain and improve range of motion, but can also lead to tissue degeneration. In the study, published in the August issue of The American Journal of Sports Medicine, researchers found combining PRP with these treatments significantly reduced their toxic effect on the cells and even improved their proliferation.


Bath Salts 101: Pharmacist Explains Party Drugs

Synthetic party drugs with dangerous hallucinogenic properties, such as those sold commercially as “bath salts,” continue to pose a significant public health risk around the country. C. Michael White — head of the Department of Pharmacy Practice in UConn’s School of Pharmacy — published a comprehensive review of synthetic cathinones in the June 2016 issue of The Journal of Clinical Pharmacology to help clinicians recognize signs of abuse and properly treat patients with adverse events, ranging from psychosis to heart disease, from the drugs. This is the third in a series of articles on drugs including molly/ecstasy and GHB that he wrote to support clinicians. He is currently working on an assessment of synthetic marijuana.
