Journal Club September 18th 2018 13:00 EDT / 18:00 UK

Share

This month, we decided to do the Journal Club a bit earlier than usual to coincide with the launch of the NAD+ Mouse Project over at Lifespan.io, which launches on September 18th. As the project is testing to see if NAD+ repletion increases lifespan, we thought that it would be an ideal time to explore NAD+ biology and take a look at a recent publication by Dr. David Sinclair. Join us on September 18th at 1:00 PM Eastern Time / 6:00 PM UK time as we stream the show live on our Facebook page.

Abstract

Nicotinamide adenine dinucleotide (NAD), the cell’s hydrogen carrier for redox enzymes, is well known for its role in redox reactions. More recently, it has emerged as a signaling molecule. By modulating NAD+-sensing enzymes, NAD+ controls hundreds of key processes from energy metabolism to cell survival, rising and falling depending on food intake, exercise, and the time of day. NAD+ levels steadily decline with age, resulting in altered metabolism and increased disease susceptibility. Restoration of NAD+ levels in old or diseased animals can promote health and extend lifespan, prompting a search for safe and efficacious NAD-boosting molecules that hold the promise of increasing the body’s resilience, not just to one disease, but to many, thereby extending healthy human lifespan.

Oliver Medvedik

Oliver Medvedik, Co-founder of Genspace citizen science laboratory in Brooklyn NY, earned his Ph.D. at Harvard Medical School in the Biomedical and Biological Sciences program. As part of his doctoral work he has used single-celled budding yeast as a model system to map the genetic pathways that underlie the processes of aging in more complex organisms, such as humans. Prior to arriving in Boston for his doctoral studies, he has lived most of his life in New York City. He obtained his bachelor’s degree in biology from Hunter College, City University of New York. Since graduating from Harvard, he has worked as a biotechnology consultant, taught molecular biology to numerous undergraduates at Harvard University and mentored two of Harvard’s teams for the international genetically engineered machines competition (IGEM) held annually at M.I.T. Oliver is also the Director of The Maurice Kanbar Center for Biomedical Engineering at the Cooper Union, New York City. The Maurice Kanbar Center for Biomedical Engineering is open to all Cooper Union faculty and students working on bioengineering projects requiring equipment and space for tissue culture, genetic engineering, biomechanics, and related research. Faculty that is currently using the facility are pursuing groundbreaking biomedical research in such fields as biomedical devices, tissue engineering, obstructive sleep apnea biomechanics also collaborating with several major New York City-based hospitals. The Kanbar Center continues to provide space for undergraduate teams participating in the international genetically engineered competition (iGEM) during the summer, as well as space for courses that offer a biological laboratory component.

    I’ve read that NAD can be boosted by taking NMN, NR, NA (nicotinic acid), or NAM (nicotinamide). Apparently taking high doses of NAM will boost NAD, but it also inhibits Sirtuins. So that’s counterproductive. But the only common issue with taking NA is the flushing. So if you don’t mind the flushing (or don’t get much flushing), is there any reason not to boost NAD by taking high doses of NA?
