An association between high blood cholesterol and breast cancer has been found in a study of more than 1 million patients over a 14-year time period in the UK.
Researchers completed a study that generated pseudogene expression profiles in 2,808 patient samples representing seven cancer types. The results indicated that the science of pseudogene expression analysis may very well play a key role in explaining how cancer occurs.
Scientists have shown that a member of the protein family known as SUMO (small ubiquitin-like modifier) is a key to why tumor cells multiply uncontrollably, especially in the case of glioblastoma.
Located deep in the human gut, the small intestine is not easy to examine. Now, researchers are developing a new imaging technique involving nanoparticles suspended in liquid to form “nanojuice” that patients would drink.
Patients suffering from osteoporosis or bone fractures might benefit from a new discovery of the protein statherin, which plays an important role in bone regeneration.
A new study by radiation oncologists has found that proton beam therapy significantly improved disease free survival and tumor control when compared to IMRT in a variety of advanced head and neck cancers.
A team of researchers has shown for the first time that stem cells created using different methods produce differing cells. The findings provide new insights into the basic biology of stem cells and could ultimately lead to improved therapies.
Researchers at the University of California, San Diego School of Medicine say a protein essential to regulating cell cycle progression – the process of cell division and replication – activates a key tumor suppressor, rather than inactivating it as previously thought.
White-bread lovers take heart. Scientists are now reporting that this much-maligned food seems to encourage the growth of some of our most helpful inhabitants — beneficial gut bacteria. In addition to this surprising find, their study also revealed that when looking at effects of food on our “microbiomes,” considering the whole diet, not just individual ingredients, is critical.
Researchers have spotted a strong family trait in two distant relatives: The channels that permit entry of sodium and calcium ions into cells turn out to share similar means for regulating ion intake, they said.
A genomic analysis of clear cell renal cell carcinoma (ccRCC), the most common form of kidney cancer, from 72 patients has uncovered 31 genes that are key to development, growth and spread of the cancer, according to researchers.
Emotional and behavioral problems show up even with low exposure to lead, and as blood lead levels increase in children, so do the problems, according to new research.
The government is expanding its "mystery disease" program, funding a network at six universities around the country to help diagnose patients with diseases so rare they've been told they're undiagnosable. The National Institutes of Health has evaluated hundreds of these cold-case patients in its campus research hospital as part of a pilot program since 2008. Demand is so great, there's a waiting list.
Bone marrow transplants can reverse severe sickle cell disease in adults, a small study by government scientists found, echoing results seen with a similar technique used in children. The researchers and others say the findings show age need not be a barrier and that the technique may change practice for some adult patients when standard treatment fails.
At 21, MS had Jennifer Molson “wheelchair bound.” But since her stem cell transplant, she has worked, driven, danced at her own wedding. The story had a room of 1,000 professional stem cell scientists sniffling loudly at the International Society for Stem Cell Research (ISSCR) meeting—said sniffling reaching a crescendo when the quiet, pretty Molson concluded: “I’m living proof stem cells can save lives.”
Almost 40 percent of pancreatic cancers– one of the deadliest forms of cancer– could be avoided in the UK through maintaining a healthy weight and not smoking, according to new research.
A discovery by Australian immunologists uncovered an additional role for antibody-making ‘B cells.’ The finding shows that B cells also participate in the development of ‘regulatory T cells.’ Until now, the only non-thymic cells known to educate the regulators were dendritic cells, which travel to the thymus to deliver ‘antigen’, samples of substances toxic to the body. We now know that B cells can do the same thing.
The risk of developing cancer increases with age. Factors like smoking and regular aspirin use also affect the risk of cancer—although in the opposite sense. Researchers from the University of Basel were now able to show that aspirin use and smoking both influence aging processes of the female genome that are connected to colorectal cancer.
The evolution of the ribosome, a large molecular structure found in the cells of all species, has been revealed in unprecedented detail in a new study.
Engineers and neuroscientists have developed a method to measure the response of an individual neuron to transcranial magnetic stimulation (TMS) of the brain. The advance will help researchers understand the underlying physiological effects of TMS.
Researchers have developed a new supercooling technique to increase the amount of time human organs could remain viable outside the body. This study was conducted in rats, and if it succeeds in humans, it would enable a world-wide allocation of donor organs, saving more lives.
New experiments have identified a compound that might halt the progression of Alzheimer’s by interfering with the role amyloid-beta plays in the formation of blood clots.
Scientists have discovered that obese individuals lack a protein that is essential for regulating blood glucose levels, causing them to face higher risks of developing diabetes.
By looking at the copy of the human genome present in healthy cells, researchers were able to build a picture of each cell's development from the early embryo on its journey to become part of an adult organ.
Optogenetics requires a light source to be implanted in the brain, where it can reach the cells that need to be controlled. Now, engineers have developed the first light-sensitive molecule that enables neurons to be silenced noninvasively, using a light source outside the skull.
