About a month ago, I had the pleasure of welcoming the Juip (pronounced “Yipe”) family from Michigan to NIH. Although you’d never guess it from this photo, two of the Juip’s five children—9-year-old Claire and 11-year-old Jake (both to my left)—have a rare genetic disease called Friedreich’s ataxia (FA). This inherited condition causes progressive damage to their nervous systems and their hearts. No treatment currently exists for kids like Claire and Jake, yet this remarkable family has turned this serious health challenge into an opportunity to raise awareness about the need for biomedical research.
One thing that helps keep the Juips optimistic is the therapeutic potential of CRISPR/Cas9, an innovative gene editing system that may someday make it possible to correct the genetic mutations responsible for FA and many other conditions. So, I’m sure the Juips were among those encouraged by the recent news that NIH-funded researchers have developed a highly versatile approach to CRISPR/Cas9-based therapies. Instead of relying on viruses to carry the gene-editing system into cells, the new approach uses tiny particles of gold as the delivery system!
My father was a folk song collector, and I grew up listening to the music of Woody Guthrie. On July 14th, folk music enthusiasts will be celebrating the 105th anniversary of Guthrie’s birth in his hometown of Okemah, OK. Besides being renowned for writing “This Land is Your Land” and other folk classics, Guthrie has another more tragic claim to fame: he provided the world with a glimpse at the devastation caused by a rare, inherited neurological disorder called Huntington’s disease.
When Guthrie died from complications of Huntington’s a half-century ago, the disease was untreatable. Sadly, it still is. But years of basic science advances, combined with the promise of innovative gene editing systems such as CRISPR/Cas9, are providing renewed hope that we will someday be able to treat or even cure Huntington’s disease, along with many other inherited disorders.
As a kid, Jesse Dixon often listened to his parents at the dinner table discussing how to run experiments and their own research laboratories. His father Jack is an internationally renowned biochemist and the former vice president and chief scientific officer of the Howard Hughes Medical Institute. His mother Claudia Kent Dixon, now retired, did groundbreaking work in the study of lipid molecules that serve as the building blocks of cell membranes.
So, when Jesse Dixon set out to pursue a career, he followed in his parents’ footsteps and chose science. But Dixon, a researcher at the Salk Institute, La Jolla, CA, has charted a different research path by studying genomics, with a focus on understanding chromosomal structure. Dixon has now received a 2016 NIH Director’s Early Independence Award to study the three-dimensional organization of the genome, and how changes in its structure might contribute to diseases such as cancer or even to physical differences among people.
When I volunteered several years ago as a physician in a small hospital in West Africa, one of the most frustrating and frightening diseases I saw was sleeping sickness. Now, an investigator supported by the NIH Common Fund aims to figure out how this disease pathogen manages to evade the human immune system.
Monica Mugnier’s fascination with parasites started in college when she picked up the book Parasite Rex, a riveting, firsthand account of how “sneaky” parasites can be. The next year, while studying abroad in England, Mugnier met a researcher who had studied one of the most devious of parasites—a protozoan, spread by blood-sucking tsetse flies, that causes sleeping sickness in humans and livestock across sub-Saharan Africa.
Cell biologists now possess an unprecedented set of laboratory tools to look inside living cells and study their inner workings. Many of these tools have only recently appeared, while others have deeper historical roots. Combining the best of the old with the best of the new, researchers now have the power to explore the biological underpinnings of life in ways never seen before.
That’s the story of this video from the lab of Roberto Weigert, an intramural researcher with NIH’s National Cancer Institute and National Institute of Dental and Craniofacial Research. Weigert is a cell biologist who specializes in intravital microscopy (IVM), an extremely high-resolution imaging tool that traces its origins to the 19th century. What’s unique about IVM is its phenomenal resolution can be used in living animals, allowing researchers to watch biological processes unfold in organs under real physiological conditions and in real time.
