Revolutions is a series that brings together a hand-picked selection of recent articles canvassing cutting-edge insights into major scientific advances. This installment brings you up to date with the ground-breaking new discoveries made around the regenerative possibilities of induced pluripotent stem cells, which can theoretically be coaxed into any kind of cell in the human body.
The findings, published on February 18, 2019 in the journal Nature Medicine, highlight a novel CRISPR/Cas9 genome-editing therapy that can suppress the accelerated aging observed in mice with Hutchinson-Gilford progeria syndrome, a rare genetic disorder that also afflicts humans. This treatment provides important insight into the molecular pathways involved in accelerated aging, as well as how to reduce toxic proteins via gene therapy.
“Aging is a complex process in which cells start to lose their functionality, so it is critical for us to find effective ways to study the molecular drivers of aging,” says Juan Carlos Izpisua Belmonte, a professor in Salk’s Gene Expression Laboratory and senior author of the paper. “Progeria is an ideal aging model because it allows us to devise an intervention, refine it and test it again quickly.”
With an early onset and fast progression, progeria is one of the most severe forms of a group of degenerative disorders caused by a mutation in the LMNA gene. Both mice and humans with progeria show many signs of aging, including DNA damage, cardiac dysfunction and dramatically shortened life span. The LMNA gene normally produces two similar proteins inside a cell: lamin A and lamin C. Progeria shifts the production of lamin A to progerin. Progerin is a shortened, toxic form of lamin A that accumulates with age and is exacerbated in those with progeria.
On July 11-12th, we return to the Cooper Union in New York City for our second annual Ending Age-Related Diseases conference, which focuses on the progress in aging research as well as the business side of biotech.
We will be bringing you the latest aging research, investment, and business knowledge from some of the top experts in the industry. We will be packing two days full of talks and discussion panels featuring the people who are developing the technologies that could change the way we regard and treat aging forever.
We are currently offering reduced ticket prices until March 31st, after which the price increases to the regular $400 cost. If you would like to take advantage of this special offer, head on over to our event ticket page to secure your place now.

A Harvard-led team is the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue, an advance they reported in Science Translational Medicine. The research, led by Wyss Institute Core Faculty member David Mooney, Ph.D., lays the foundation for a host of clinical applications in restorative dentistry and regenerative medicine more broadly, such as wound healing, bone regeneration, and more.
Chemistry researchers at Oregon State University have patented a method for making anti-leukemia compounds that until now have only been available via an Asian tree that produces them.
The synthesis of cephalotaxine and homoharringtonine (HHT) paves the way toward less-expensive, more readily available leukemia drugs whose production is not subject to the risks and inefficiencies associated with harvesting natural sources.
Also, the synthesis of cephalotaxine opens the door to preparing other, structurally related compounds for evaluation as potential new cancer drugs.
