Researcher identifies mechanisms that may cause resistance to BRAF inhibitor

BRAF mutation occurs in between 40% and 50% of metastasising melanomas (skin cancers), boosting tumour growth.

Cells may need some reactive forms of oxygen to maintain health

Within our bodies, high levels of reactive forms of oxygen can damage proteins and contribute to diabetic complications and many other diseases.

New fluorescence microscopy approach improves image resolution by merging three views into one

Researchers have developed a new fluorescence microscopy approach that significantly improves image resolution by acquiring three views of a sample at the same time. Their new method is particularly useful for watching the dynamics of biological processes, which can provide insights into how healthy cells work and what goes wrong when diseases occur.

Good ceramides in skin creams and shampoos may hold promise for Alzheimer's treatment

The best-selling lipid in the world, often prominently featured on skin cream and shampoo labels, appears to also hold promise for Alzheimer's treatment, scientists say.

Study offers new hope for preventing chronic lung disease in premature infants

By triggering a process called autophagy -- in which cells literally engulf their own insides --researchers from Drexel University and Yale University were able to decrease lung injury in mice that were exposed to high concentrations of oxygen.

Modifications to RUNX3 protein may promote cancer progression

Scientists from the Cancer Science Institute of Singapore at the National University of Singapore have discovered that modifications to a protein called RUNX3 may promote cancer progression.

UC Davis scientists show how cells control DNA synthesis in mitochondria

Aging, neurodegenerative disorders and metabolic disease are all linked to mitochondria, structures within our cells that generate chemical energy and maintain their own DNA. In a fundamental discovery with far-reaching implications, scientists at the University of California, Davis, now show how cells control DNA synthesis in mitochondria and couple it to mitochondrial division.

Selfish mutant mtDNA exploits cellular defenses to cause many diseases

Mitochondrial disorders are a chameleon-like set of diseases that take many different forms and vary widely from individual to individual.

UCI researchers use new imaging method to measure fat metabolism

A team from the University of California, Irvine and supported by the National Institute of Biomedical Imaging and Bioengineering has used a new imaging technique to measure how people break down dietary fat into products the cells of their bodies can use.

Researchers determine how Ki-67 protein disperses chromosomes in dividing cells

Billions of your cells divide every day. Cell division fuels growth and also replaces short-lived cells in some organs, like your skin, blood, and gut.

Pain reliever appears to help preserve vision in animal model of retinal degeneration

A pain medicine that potently activates a receptor vital to a healthy retina appears to help preserve vision in a model of severe retinal degeneration, scientists report.

Scientists discover link between two genes involved in PD and autoimmune diseases

A study publish in the journal CELL indicates that two genes associated with Parkinson's disease (PD) are key regulators of the immune system, providing direct evidence linking Parkinson's to autoimmune disease.

Mutant fruit flies provide insight into origins of Parkinson's disease

The neurodegeneration that occurs in Parkinson’s disease is a result of stress on the endoplasmic reticulum in the cell rather than failure of the mitochondria as previously thought, according to a study in fruit flies.

Researchers reveal novel mechanism of smoke induced collapse of protein homeostasis in COPD

Few threats to public health are as perilous as cigarette smoking, with more than 435,000 Americans dying each year of tobacco-related pulmonary illnesses such as chronic obstructive pulmonary disease (COPD).

Study sheds new light on how overeating may lead to more eating

Research is finally beginning to shed light on some of the reasons that extra weight is difficult to shed permanently. Now, a new study has uncovered another method by which the gut senses how much food a person eats and relays that to the brain.

New and inexpensive technique could help meet global demands for malaria drug

A new and inexpensive technique for mass-producing the main ingredient in the most effective treatment for malaria, artemisinin, could help meet global demands for the drug, according to a study to be published in the journal eLife.

Unlocking the dark proteome: an interview with Dr Kriwacki

The term dark proteome refers to proteins whose structural features and thus functions are not well understood. Many proteins within the dark proteome do not fold into stable three-dimensional structures. These proteins are called intrinsically disordered proteins (IDPs) and feature highly flexible, disordered confirmations.

MDI Biological Laboratory to offer one-week course in Quantitative Fluorescence Microscopy

Science professionals, doctoral and postdoctoral students from across the country will gather May 20 through 27 at the MDI Biological Laboratory in Bar Harbor, Maine, for an intensive one-week course in Quantitative Fluorescence Microscopy.

Rapamycin drug could target neural damage linked to Leigh syndrome

Salk Institute scientists showed how an FDA-approved drug boosts the health of brain cells by limiting their energy use. Like removing unnecessary lighting from a financially strapped household to save on electricity bills, the drug--called rapamycin--prolongs the survival of diseased neurons by forcing them to reduce protein production to conserve cellular energy.

Salk scientists reveal how cellular fuel gauge plays unexpected role in development

Salk scientists have revealed how a cellular "fuel gauge" responsible for monitoring and managing cells' energy processes also has an unexpected role in development. This critical link could help researchers better understand cancer and diabetes pathways.
