Supercomputer simulations have shown that clusters of a protein linked to cancer warp cell membranes, according to scientists at The University of Texas Health Science Center at Houston (UTHealth) Medical School. This research on these protein clusters, or aggregates as scientists call them, could help guide design of new anticancer drugs.
A piece of detective work has mapped a special gene variant among Greenlanders that plays a particularly important role in the development of type 2 diabetes. The results can be used to improve prevention and treatment options for those genetically at-risk.
Maybe turning to sleep gadgets—wristbands, sound therapy and sleep-monitoring smartphone apps—is a good idea. A new University of Oregon-led study of middle-aged or older people who get six to nine hours of sleep a night think better than those sleeping fewer or more hours.
In a new study, scientists took a molecular-level journey into microtubules, the hollow cylinders inside brain cells that act as skeletons and internal highways. They watched how a protein called tubulin acetyltransferase (TAT) labels the inside of microtubules.
By themselves, PAX3 and MAML3 don’t cause any problems. However, when they combine during an abnormal but recurring chromosomal mismatch, they can be dangerous. The result is a chimera—a gene that is half of each—and that causes biphenotypic sinonasal sarcoma. The tumor usually begins in the nose and may infiltrate the rest of the face, requiring disfiguring surgery to save the individual.
Scientists and physicians at UC San Francisco are leading a $26 million, multi-institutional research program in which they will employ advanced technology to characterize human brain networks and better understand and treat a range of common, debilitating psychiatric disorders.
Scientists have discovered a pair of genes that normally keeps eating schedules in sync with daily sleep rhythms, and, when mutated, may play a role in so-called night eating syndrome.
Scientists have shown how switching off a key protein in pancreatic cells slows the spread of the disease to other tissues, a key step which can mean patients have just weeks to live.
A Stanford electrical engineer has invented a way to wirelessly transfer power deep inside the body and then use this power to run tiny electronic medical gadgets such as pacemakers, nerve stimulators or new sensors and devices yet to be developed.
University of Utah researchers devised a way to watch newly forming AIDS virus particles emerging or “budding” from infected human cells without interfering with the process. The method shows a protein named ALIX gets involved during the final stages of virus replication, not earlier, as was believed previously.
Researchers at MIT and the University of Vienna have created an imaging system that reveals neural activity throughout the brains of living animals. This technique, the first that can generate 3-D movies of entire brains at the millisecond timescale, could help scientists discover how neuronal networks process sensory information and generate behavior.
For a century, biologists have thought they understood how the gooey growth that occurs inside cells causes their protective outer walls to expand. Now, researchers have captured the visual evidence to prove the prevailing wisdom wrong.
In our sixth video, Andrew Wiecek wraps up the discussion by taking a look at one of the therapeutic areas that could be significantly improved by personalized medicine: cancer. The approach is similar to comparing apples to apples, he says.
It’s common knowledge that all organisms inherit their mitochondria—the cell’s “power plants”—from their mothers. But what happens to all the father’s mitochondria? How—and why—paternal mitochondria are prevented from getting passed on to their offspring after fertilization is still shrouded in mystery.
In a proof-of-principle clinical trial, researchers have demonstrated that virotherapy— destroying cancer with a virus that infects and kills cancer cells but spares normal tissues— can be effective against the deadly cancer multiple myeloma.
