UC Berkeley biologists discover potential target for unisex contraceptives

UC Berkeley biologists have discovered the switch that triggers the power kick sperm use to penetrate and fertilize a human egg, uncovering a possible source of male infertility but also a potential target for contraceptives that work in both men and women.

DNA sequence features predict genome-wide binding pattern of key protein involved in brain disorders

Researchers from the University of Illinois at Urbana-Champaign and the University of California-Davis are combining in vivo experimentation with computation for highly accurate prediction of the genome-wide binding pattern of a key protein involved in brain disorders.

Self-repairing cancer cells: A new pathway for cancer treatment

With narrow bodies and no collarbones, mice are able to squeeze through holes as small as a quarter-inch in diameter. Cancer cells similarly are able to migrate through extremely tight quarters but with a major difference: The journey often comes at a price - the deformation and, in some cases, rupture of the outer lining of a cell's nucleus. While deformation and rupture can sometimes lead to cell death, the cell - about 90 percent of the time - also has the ability to repair itself.

Defective PTCHD1 gene in brain creates symptoms associated with autism and ADHD

Evidence is mounting that a gene called PTCHD1 helps the brain sort between important sights and sounds — and distractions. This gene is active in a brain region that attaches more attention to a conversation with your boss, for instance, than to an air conditioner buzzing in the background.

New type of nerve cells appears to control feeding behaviors in mice

While researching the brain's learning and memory system, scientists at Johns Hopkins say they stumbled upon a new type of nerve cell that seems to control feeding behaviors in mice. The finding, they report, adds significant detail to the way brains tell animals when to stop eating and, if confirmed in humans, could lead to new tools for fighting obesity. Details of the study will be published by the journal Science on March 18.

UT Southwestern researchers identify new role for protein linked to neurological disorders and cancers

Researchers at UT Southwestern Medical Center have identified a second role for a class of RNA-binding proteins, revealing new insights about neurological diseases and conditions associated with this protein such as autism, epilepsy, and certain types of cancer.

UC San Diego researchers use CRISPR-Cas9 system to target RNA in living cells for first time ever

The genetic code stored in DNA determines everything from the color of our eyes to our susceptibility to disease. This has motivated scientists to sequence the human genome and develop ways to alter the genetic code, but many diseases are linked to a different fundamental molecule: RNA.

New drug could transform treatment of metastatic triple negative breast cancer

A team of investigators from Houston Methodist Research Institute may have transformed the treatment of metastatic triple negative breast cancer by creating the first drug to successfully eliminate lung metastases in mice.

Could environmental toxins trigger amyloid plaques in the brain? An interview with Dr Paul Alan Cox

Many Chamorro villagers on the island of Guam perished from a puzzling paralytic disease that combines aspects of ALS, Alzheimer's, and Parkinson's disease.

Scientists discover brain mechanisms that separate food consumption from cravings

Researchers investigating eating disorders often study chemical and neurological functions in the brain to discover clues to overeating. Understanding non-homeostatic eating -- or eating that is driven more by palatability, habit and food cues -- and how it works in the brain may help neuroscientists determine how to control cravings, maintain healthier weights and promote healthier lifestyles. Scientists at the University of Missouri recently discovered the chemical circuits and mechanisms in the brain that separate food consumption from cravings. Knowing more about these mechanisms could help researchers develop drugs that reduce overeating.

First atomic-scale view of interaction between HIV capsid and host protein cyclophilin A

A new study offers the first atomic-scale view of an interaction between the HIV capsid - the protein coat that shepherds HIV into the nucleus of human cells - and a host protein known as cyclophilin A. This interaction is key to HIV infection, researchers say.

Unlocking H5N1 virus replication: an interview with Martin Blackledge

We were able to show that one small domain of the polymerase, the part that is essential for entry of a piece of the polymerase into the cell nucleus, changes its conformation to allow it to interact with the transporter protein than takes it into the nucleus.

New research sheds light on circadian rhythms

New research sheds light on how the rhythms of daily life are encoded in the brain. Scientists at Washington University School of Medicine in St. Louis have discovered that different groups of neurons, those charged with keeping time, become active at different times of day despite being on the same molecular clock.

Researchers discover unexpected mechanism linked to aldosterone-induced heart damage

When the heart begins to fail, the body does everything in its power to fix the situation. But sometimes, those compensatory mechanisms ultimately do more harm than good. Such is the case with the adrenal hormone aldosterone, which stimulates the heart to pump harder, causing greater damage to the heart muscle.

Researchers reveal how stress conditions favor lytic reactivation of herpesviruses

Hiding their DNA genome inside the nucleus of the infected cells, the herpesviruses establish a lifelong infection in humans. Not well defined stress conditions are known to wake up these parasites from their dormancy - the latent phase - and reactivate the production of new viral progeny, eventually causing cell death by lysis - the lytic phase.

Longer, more intense period of rehabilitation may boost recovery after stroke or traumatic injury

Cognitive and functional recovery after a stroke or traumatic injury requires intense rehabilitative therapy to help the brain repair and restructure itself. New findings by researchers at University of California, San Diego School of Medicine report that not only is rehabilitation vital - in an animal model, rats with cortical injury that did not receive intensive rehab did not rebuild brain structure or recover function - but that a longer, even more intense period of rehabilitation may produce even greater benefit.

Study identifies new mechanism for controlling HIV replication

Researchers at University of California, San Diego School of Medicine have discovered that HIV infection of human immune cells triggers a massive increase in methylation, a chemical modification, to both human and viral RNA, aiding replication of the virus.

Rehabilitation-induced reorganization of damaged brain circuits responsible for functional recovery

Each year millions of people worldwide suffer from stroke, which can occur to anyone at any time. While some may recover completely, the majority of survivors will experience some form of impairment that requires a lengthy process toward partial or full recovery of functioning. Therefore, continuous improvement of rehabilitation methods is needed to ensure more positive long-term outcomes among survivors.

Scientists discover role of nucleocytoplasmic transport in specific forms of ALS and FTD

Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are two devastating adult-onset neurodegenerative disorders.

Astrocytes implicated in preclinical AD

Astrocytes are activated in the brains of people with autosomal dominant Alzheimer’s disease long before symptoms appear and even before amyloidosis begins, a study shows.
