Scientists have determined the most detailed picture yet of a crucial part of the hepatitis C...
Researchers have shown that tiny quantities of the protein tau can be enough to kick-start an...
A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure.
A research team has identified an immune cell protein that is critical to setting off the body’s initial response against viral infection.
Using a new method to catch elusive “jumping genes” in the act, researchers have found two human proteins that are used by one type of DNA to replicate itself and move from place to place.
Researchers have recently developed a new technique for profiling enzyme activities in cell lysate, a fluid containing the internal contents of cells, allowing them to analyze the enzyme reactions within cells.
The protein in cells that most often drives the development of cancers has eluded scientists’ efforts to block it for three decades– until now.
A research team has found that a specific chemical compound, an aldehyde, can activate UCP1, a protein known as UCP1 that enables babies or hibernating animals to keep warm without shivering, under certain conditions, and that could also trigger fat burning.
Researchers have now solved the structure of a key protein in the Nipah virus, which could pave the way for the development of a much-needed antiviral drug.
Scientists have solved a long-standing conundrum about the immune system and in so doing may have found a new way to boost or reduce immunity therapeutically.
A protein engineered by combining proteins active in HIV and Moloney murine leukemia virus (MLV) replication may lead to safer, more effective retroviral gene therapy.
New research using tissue from the Parkinson's UK Brain Bank suggests that a protein called alpha-synuclein causes the spread of nerve cell death in multiple system atrophy (MSA), a Parkinson's-like condition.
A study new study found that an enzyme that edits RNA may loosen the genome’s control over invasive snippets of DNA that affect how genes are expressed. In fruit flies, that newly understood mechanism appears to contribute to differences among individuals such as eye color and life span.
Two groups of scientists have made complementary discoveries that break new ground on efforts to turn back the body’s clock on cellular activity, paving the way for a better understanding of stem cells, tissue growth and regeneration.
Scientists have demonstrated that that cancer cells need a protein called Bod1 to grow and divide. When this protein is removed, cancer cells lose control of cell division and die.
Imagine a 1950s horror movie monster— a creeping, gelatinous, gluey tangle of gunk that strangles everything around it. That’s what amyloid plaques are like when they form in body tissues.
A new study clarifies the role of calcium signaling in the medically significant communication between skin cells that occurs during wound healing.
Using cells from the stem of a seedling as a model system, biologists are seeking to understand the molecular mechanisms that organize and pattern the hundreds or thousands of microtubular “bones” of the plant cytoskeleton.
Cell biologists have teased apart two integral components of the machinery that causes cells to move. Their discovery shows that cellular projections, which act as hands to help a cell "crawl," are apparently always initiated by a network of message-relaying proteins inside the cell.
A colorful wheel developed bioengineers to visualize protein interactions has won an international competition for novel strategies to study the roots of breast cancer.
The formation of long-term memory is dependent on protein synthesis at a specific location and time in brain tissues. A research team recently developed a new imaging technique to pinpoint exactly where and when cells produce new proteins.
A group of researchers and students has developed a new Web program that will help scientists visually analyze DNA and protein sequence patterns faster and more efficiently than ever before.
A protein increased by endurance exercise has been isolated and given to non-exercising mice, turning on genes that promote brain health and encourage the growth of new nerves involved in learning and memory, researchers say.
Often deadly “triple-negative” breast cancers might be effectively treated in many cases with a drug that targets a previously unknown vulnerability in the tumors, according to a new study. Researchers found blocking cystine from entering triple-negative breast cancer cells can significantly inhibited their growth in culture and when the cancer cells were transplanted into mice.
Naked mole rats have what any animal would want. They live long lives—about 30 years—and stay healthy until the very end. Now, biologists have new insights into the animal's longevity—better-constructed proteins, which are involved in nearly all functions of an animal cell, and consequently, are essential to all organisms.
Blood from HIV-infected human subjects shows an immune response against a cat AIDS virus protein, a surprise finding that could help scientists find a way to develop a human AIDS vaccine, researchers report. This discovery supports further exploration of a human AIDS vaccine derived from regions of the feline AIDS virus.
Researchers have added a new layer of information to the Cancer Cell Line Encyclopedia related to the proteins around which DNA gets wrapped in the cell. This proteomics technique points the way to a potential drug target for pediatric acute lymphoblastic leukemia (ALL).
