How naked mole rats conquered pain—and what it could mean for us

By Elizabeth Pennisi

Although it has a face—and body—that only a mother could love, the naked mole rat has a lot to offer naked-mole-ratbiomedical science. It lives 10 times longer than a mouse, almost never gets cancer, and doesn’t feel pain from injury and inflammation. Now, researchers say they’ve figured out how the rodents keep this pain away.

“It’s an amazing result,” says Harold Zakon, an evolutionary neurobiologist at the University of Texas, Austin, who was not involved with the work. “This study points us to important areas … that might be targeted to reduce this type of pain.”

Naked mole rats are just plain weird. They live almost totally underground in colonies structured like honey bee hives, with hundreds of workers servicing a single queen and her few consorts. To survive, they dig kilometers of tunnels in search of large underground tubers for food. It’s such a tough life that—to conserve energy—this member of the rodent family gave up regulating its temperature, and they are able to thrive in a low-oxygen, high–carbon dioxide environment that would suffocate or be very painful to humans. “They might as well be from another planet,” says Thomas Park, a neuroscientist at the University of Illinois, Chicago.

Hype vs. hope in medical research

This might seem a strange question coming from one of the leaders of the Human Genome Project, and the director of the Broad Institute, which brings together researchers from Harvard, MIT, and Harvard-affiliated hospitals to accelerate the understanding and treatment of disease.

I think the answer is a clear yes — and a resounding no. The contradiction highlights a thorny challenge in the ongoing conversation between scientists and the public.

This summer, I gave a talk at the Aspen Ideas Festival in which I discussed the need to accelerate medical progress through data-sharing and expressed the hope that, within the next 30 to 40 years, we might have enough knowledge to be able to turn cancer, for the majority of patients, into a treatable chronic condition rather than a lethal disease.

Gene editing shows promise as a new treatment for sickle cell disease, according to a study published in the online journal Science Translational Medicine.

Experts from the University of California, Berkeley, UCSF Benioff Children’s Hospital Oakland Research Institute (CHORI), and the University of Utah School of Medicine have found success in correcting the blood cell mutation in tests of the blood of both mice and human sickle cell patients using CRISPR-Cas9, a genome “scissor” that can cut out and edit a DNA sequence.

After CRISPR was used to correct the mutated hematopoietic stem cells — precursor cells that mature into the hook-shaped hemoglobin characteristic of sickle cell disease, the corrected blood stem cells produced healthy hemoglobin. Following reintroduction into the mice, the genetically engineered stem cells remained in circulation for at least four months — a significant indication that any potential therapy would be lasting.  Read more

Humans aren’t the only great apes that can ‘read minds’

By Virginia Morell

All great mind reading begins with chocolate. That’s the basis for a classic experiment that tests whether children have something called theory of mind—the ability to attribute desires, intentions, and knowledge to others. When they see someone hide a chocolate bar in a box, then leave the room while a second person sneaks in and hides it elsewhere, they have to guess where the first person will look for the bar. If they guess “in the original box,” they pass the test, and show they understand what’s going on in the first person’s mind—even when it doesn’t match reality.

For years, only humans were thought to have this key cognitive skill of attributing “false belief,” which is believed to underlie deception, empathy, teaching, and perhaps even language. But three species of great apes—chimpanzees, bonobos, and orangutans—also know when someone holds a false belief, according to a new study published today in Science. The groundbreaking study suggests that this skill likely can be traced back to the last common ancestor of great apes and humans, and may be found in other species. Read more

This dog is at the forefront of cancer research

By Andrea Morabito

Three to four days a week, Philadelphia veterinarian Clint Kuban drops off his 3-year-old German shepherd, Tsunami, at the Penn Vet Working Dog Center for her eight-hour shift.

But the pooch isn’t just participating in agility, obedience and search training — she’s also on the front lines of cancer research.

Kuban is one of six fourth-year students at the University of Pennsylvania School of Veterinary Medicine followed in the new Animal Planet series “Life at Vet U,” premiering Saturday at 10 p.m. Tsunami has worked on the center’s ovarian-cancer-detection research project since it launched in 2013 to study whether odors emanating from ovarian tissue can provide a reliable method for early detection.

As the first local mosquito-borne transmissions of the Zika virus are being reported in the continental United States, an investigational vaccine developed by the National Institute of Allergy and Infectious Diseases (NIAID) at the National Institutes of Health (NIH) is entering phase 1 clinical trials.

At least 80 people between the ages of 18 and 35 years will be enrolled in the trial, which will take place at 3 study sites in the United States including the NIH Clinical Center in Bethesda, Maryland. The trial will test vaccine safety and immunogenicity.

Scientists at NIAID’s Vaccine Research Center developed the DNA vaccine, which does not contain Zika virus and therefore cannot cause an infection. The vaccine contains a genetically engineered plasmid—a small, circular piece of DNA—that encodes Zika virus proteins. These proteins assemble into viruslike particles that provoke an immune response against the virus. This response is composed of both neutralizing antibodies and T cells.

Researchers from the University of Maryland Fischell Department of Bioengineering and the University of Maryland School of Medicine report a new way to “turn off” the harmful immune attack that occurs during autoimmune diseases such as multiple sclerosis (MS), while keeping healthy functions of the immune system intact.

“Our lab is combining immunology and nanotechnology to reprogram how the immune system responds to self-cells in the brain that are mistakenly attacked during MS,” said BIOE Assistant Professor Christopher Jewell, corresponding author on the new report. “The finding, conducted in cells and pre-clinical animal models of MS, could lead to new approaches for reversing paralysis in MS, or better therapies for other autoimmune diseases.” Read more

Letter to The Guardian

Nonhuman primates have long played a key role in life-changing medical advances. A recent white paper by nine scientific societies in the US produced a list of 50 medical advances from the last 50 years made possible through studies on nonhuman primates. These included: treatments for leprosy, HIV and Parkinson’s; the MMR and hepatitis B vaccines; and earlier diagnosis and better treatment for polycystic ovary syndrome and breast cancer.

The biological similarities between humans and other primates mean that they are sometimes the only effective model for complex neurodegenerative diseases such as Parkinson’s. More than 10 million people suffer from Parkinson’s worldwide, and a recent study estimated that one in three people born in 2015 will develop dementia in their lifetime. Primate research offers treatments, and hope for future treatments, to patients and their families. Already over 200,000 Parkinson’s patients have had their life dramatically improved thanks to deep brain stimulation surgery, which reduces the tremors of sufferers. This treatment was developed from research carried out in a few hundred monkeys in the 1980s and 1990s. Read more

San Antonio scientists are part of a push to develop laboratory animal models to study the Zika virus. Baboons and monkeys may be key to unlocking new treatments and vaccines.

Marmosets are a New World monkey that lives in Brazil, where it’s been infected with Zika in the wild. Now, scientists at Texas Biomedical Research Institute are using the small primate, about the size of a guinea pig, to test possible vaccines and treatments for Zika.

“When you infect marmoset with a human virus, the disease looks very much like what you see in humans,” explained Jean L. Patterson, Ph.D., scientist in the virology department. Read more
