Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

Human breast milk bought online poses serious health risks

The recent craze for human breast milk, which has become a lucrative online market, poses serious health risks, according to British experts.

Taranis protein could hold key to a good night's sleep

Most of us need seven to eight hours of sleep a night to function well, but some people seem to need a lot less sleep. The difference is largely due to genetic variability. In research published online June 18th in Current Biology, researchers report that two genes, originally known for their regulation of cell division, are required for normal slumber in fly models of sleep: taranis and Cyclin-dependent kinase 1 (Cdk1).

Scientists identify four melanoma subtypes that share common 'downstream' signaling pathways

Cutaneous melanoma, the most deadly form of skin cancer, is now believed to be divided into four distinct genomic subtypes, say researchers at The University of Texas MD Anderson Cancer Center, a finding that could prove valuable in the ever-increasing pursuit of personalized medicine.

Preventing neutrophils from producing NETs can accelerate wound healing in diabetic mice

One of the body's tools for fighting off infection in a wound may actually slow down the healing process, according to new research by a team of Harvard University, Boston Children's Hospital, and Penn State University scientists.

Three studies describe advances toward development of antibodies to stop HIV

A trio of studies being published today in the journals Science and Cell describes advances toward the development of an HIV vaccine. The three study teams all demonstrated techniques for stimulating animal cells to produce antibodies that either could stop HIV from infecting human cells in the laboratory or had the potential to evolve into such antibodies.

Automated droplet-based surface sampling probe analyzes liver biopsy sample in 10 minutes

Surgeons could know while their patients are still on the operating table if a tissue is cancerous, according to researchers from the Department of Energy's Oak Ridge National Laboratory and Brigham and Women's Hospital/Harvard Medical School.

Sequence of immunizations could be the promising route to HIV vaccine

The secret to preventing HIV infection lies within the human immune system, but the more-than-25-year search has so far failed to yield a vaccine capable of training the body to neutralize the ever-changing virus. New research from The Rockefeller University, and collaborating institutions, suggests no single shot will ever do the trick. Instead, the scientists find, a sequence of immunizations might be the most promising route to an HIV vaccine.

International researchers identify previously unknown genetic immunodeficiency

An analysis of five families has revealed a previously unknown genetic immunodeficiency, says an international team led by researchers from Boston Children's Hospital. The condition, linked to mutations in a gene called DOCK2, deactivates many features of the immune system and leaves affected children open to a unique pattern of aggressive, potentially fatal infections early in life.

IDIBELL researchers identify potential treatment for type 2 diabetes

Currently, there are more than 350 million type 2 diabetics and according to the World Health Organization (WHO) by 2030 it will be the 7th leading cause of death worldwide.

University of Delaware researchers identify prime suspects in cataract formation

When cataracts encroach on the eyes, the only effective remedy is to surgically replace the eyes' lenses with synthetic substitutes. But what if scientists found a way to delay or prevent cataracts from forming in the first place? Researchers at the University of Delaware may have found such an opportunity by identifying the prime suspects in the formation of cataracts - deficiency of two genes that encode regulatory proteins.

Nucleoporin proteins play significant role in maintaining embryonic stem cells

What if you found out that pieces of your front door were occasionally flying off the door frame to carry out chores around the house? That's the kind of surprise scientists at the Salk Institute experienced with their recent discovery that nucleoporins -- proteins that act as cellular 'doorways' to help manage what goes in and out of a cell's nucleus -- are actually much bigger players in expressing genes than previously thought.

Study demonstrates potential of new approach for sorting out BRCA1 gene variants

Patients seeking certainty in genetic tests often receive a perplexing result. Many learn they carry a 'variant of unknown significance' of a disease-linked gene. Such variants might -- or equally might not -- increase disease risk.

Experimental AIDS vaccine candidate stimulates immune system to block infection in animal model

New research led by scientists at The Scripps Research Institute, International AIDS Vaccine Initiative and The Rockefeller University shows that an experimental vaccine candidate can stimulate the immune system to block HIV infection in mice.

EPFL scientists show how a major effector protein binds chromatin and regulates gene expression

Inside the cell, DNA is tightly coiled and packed with several proteins into a structure called "chromatin", which allows DNA to fit in the cell while also preventing genes from being expressed at the wrong time. Guided by a chemical "barcode", specialized effector proteins can bind chromatin and either unwind it or compact further to activate or silence genes.

Vinculin protein levels increase with age to alter shape, performance of cardiac muscle cells

The human heart makes precious few new cells but manages to generate billions of life-sustaining beats as it grows old.

Ragweed pollen can trigger strong allergic reactions

Ragweed (Ambrosia artemisiifolia) - an otherwise unremarkable plant - produces pollen that can trigger strong allergic reactions such as asthma even in very small quantities. Scientists from Technische Universität München (TUM) and Helmholtz Zentrum München have now published a joint study showing that the substance previously identified as the major allergen only induces such a vigorous allergic response in combination with the adenosine also present in the pollen.

Findings could lead to treatments for chronic pain caused by nerve damage

Non-narcotic treatments for chronic pain that work well in people, not just mice, are sorely needed. Drawing from human pain genetics, an international team led by Boston Children's Hospital demonstrates a way to break the cycle of pain hypersensitivity without the development of addiction, tolerance or side effects.

Melanoma patients with high levels of H2A.Z.2 protein less likely to survive

Melanoma patients with high levels of a protein that controls the expression of pro-growth genes are less likely to survive, according to a study led by researchers at Icahn School of Medicine at Mount Sinai and published online in the journal Molecular Cell.

Rare form of autoimmune syndrome may be tied to mutations in AIRE gene

A hereditary autoimmune disease that was thought to be exceedingly rare may have a less severe form that affects one in 1,000 people or even more, according to new research conducted at the Weizmann Institute of Science, in Israel, and the University of Bergen, in Norway.
