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.

Restricting the blood flow to the arm may improve outcomes of heart surgery

A new study suggests that patients undergoing coronary artery bypass surgery may have improved outcomes by having a procedure done that temporarily restricts the blood flow in their arm.

Proteins involved in fragile X syndrome identified

The interplay of two proteins that bind to messenger RNA, a molecule that mediates translation of the information encoded in genes into proteins, triggers the appearance of fragile X-associated tremor/ataxia syndrome (FTAX), a late-life disorder associated with the gene that causes fragile X syndrome in children, said researchers from Baylor College of Medicine in Houston and Emory University School of Medicine in a report that appears today in the journal Neuron.

New understanding of how HSV-1 attacks cells

A team of University of Kentucky researchers has identified the roles that herpes simplex virus type 1 (HSV-1) proteins play during the invasion of cells and the formation of skin lesions known as cold sores and fever blisters.

Reactivating a critical gene lost in kidney cancer reduces tumor growth

Researchers at Mayo Clinic Jacksonville, have found that a key gene is often silenced in clear cell renal cell carcinoma, the most common type of kidney cancer, and when they restored that gene in human kidney cancer cells in culture and animal experiments, tumors stopped growing and many disappeared.

Scientists discover new mechanism for viral replication

Researchers at the University of Pennsylvania School of Medicine have identified a new strategy that Kaposi's Sarcoma Associated Herpesvirus (KSHV) uses to dupe infected cells into replicating its viral genome.

Obesity and aversion to exercise could enhance the risk of pancreatic cancer

Obesity and aversion to exercise have become hallmarks of modern society and a new study suggests that a blood protein linked to these lifestyle factors may be an indicator for an increased risk of developing pancreatic cancer.

New target for the development of anti-influenza drugs

Scientists at Cure Lab, Inc., a biotechnology company based in Canton, Massachusetts, in collaboration with researchers at Boston University and Harvard Medical School have discovered a potential new target for the development of anti-influenza (flu) drugs, including those that may be effective against potentially pandemic influenza strains like H5N1.

Sirtuin protein instrumental in fat production and metabolism

A new Joslin Diabetes Center-led study has identified a protein found in fat cells that may play a major role in how fat is produced and stored, offering a new target for treatments to prevent obesity and reduce the risk for type 2 diabetes.

Mice use specialized neurons to detect carbon dioxide in the air

For mice, carbon dioxide often means danger - too many animals breathing in too small a space or a hungry predator exhaling nearby.

Scientists describe a new way of creating novel enzymes

The intricate interplay of proteins and other chemicals that underlies most biological activities requires the participation of enzymes, specialized molecules that accelerate chemical reactions between molecules.

Low levels of key protein may indicate pancreatic cancer risk

A protein that dwindles in response to obesity and a sedentary lifestyle may one day help doctors predict which people are at increased risk for pancreatic cancer, new research by Dana-Farber Cancer Institute and collaborating scientists indicates.

Researchers discover how a protein modulates the inflammatory response in acute respiratory distress syndrome

Researchers at the University of Illinois at Chicago College of Medicine have discovered how a protein modulates the inflammatory response in sudden, life-threatening lung failure.

HIV protein both causes brain injury and prevents its repair

New evidence reported in the August issue of Cell Stem Cell, a publication of Cell Press, offers a novel perspective on how the HIV/AIDS virus leads to learning and memory deficits, a condition known as HIV-associated dementia.

Effectiveness of mouse breeds that mimic Alzheimer's disease symptoms questioned

Scientists have shown that recently developed mouse breeds that mimic the symptoms of Alzheimer's disease (AD) may not be as effective as previously assumed.

New findings on cholesterol metabolism

A team of researchers investigating cholesterol and lipid transport has performed experiments that cast serious doubt on the dominant hypothesis of how the body rids its cells of "bad" cholesterol (LDL) and increases "good" cholesterol (HDL).

New insight into fragile X tremor/ataxia syndrome

Researchers have reported new insight into the pathology underlying a recently identified neurological disorder that strikes middle-aged adults that is caused by alterations in the same gene that causes fragile X syndrome.
