Tailoring cancer treatments to individual patients

Attempts to eradicate cancer are often compared to a “moonshot” — the successful effort that sent the first astronauts to the moon. But imagine if, instead of Newton's second law of motion, which describes the relationship between an object's mass and the amount of force needed to accelerate it, we […]

Discovery could help treat cancer more effectively

University of Alberta researchers have discovered a mechanism that may make cancer cells more susceptible to treatment. Post-doctoral fellow Mohammad Ali and his research team found that the protein RYBP prevents DNA repair in cancer cells, including breast cancer, which in turn could make chemo or radiation therapy more effective. […]

Scientists discover how parasite hacks into its host’s genes in plant-to-plant warfare

Research at Virginia Tech and Penn State that has revealed how a parasitic plant utilizes cross-species gene manipulation to attack its victims could lead to a method to engineer parasite-resistant plants. Dodder, a parasitic plant that damages millions of dollars' worth of crops each year, is a stealthy invader that […]

Stanford mechanical engineers give breast cancer research a boost

One of the most puzzling questions in breast cancer research is why some tumors stay put, while rogue cells from others break free and spread to surrounding tissues, the first step toward creating a more lethal disease. Although researchers have found some signs in mutated genes or telltale proteins on […]

Two UO chemistry projects shed new light on a cancer drug

One of the most widely used drugs to fight cancer could become more effective and safer, based on findings emerging from the lab of UO chemist Vickie DeRose. In two recently published papers, separate projects using different approaches and led by two of DeRose’s doctoral students have made new predictions for […]

Dirt-dwelling microbe produces potential anti-melanoma weapon

A type of soil-dwelling bacterium produces molecules that induce death in melanoma cells, research at Oregon State University shows. The molecule is a secondary metabolite, also known as a natural product, of Streptomyces bottropensis, and its properties are important because there are not many therapies that effectively manage melanoma, the […]

Supercharged antibiotics could turn tide against superbugs

An old drug supercharged by University of Queensland researchers has emerged as a new antibiotic that could destroy some of the world’s most dangerous superbugs. The supercharge technique , led by Dr Mark Blaskovich and Professor Matt Cooper from UQ’s Institute for Molecular Bioscience (IMB), potentially could revitalise other antibiotics. Antibiotic-resistant bacteria […]

Stem cell transplant for severe scleroderma improves survival, quality of life

New clinical trial findings show that a therapeutic regimen involving transplantation of a person’s own blood-forming stem cells can improve survival and quality of life for people with severe scleroderma, a life-threatening autoimmune disease. The regimen, known as myeloablative autologous hematopoietic stem cell transplant (HSCT), includes chemotherapy and total body […]

Cellular barcoding helps scientists understand the behavior of stem cells

By tagging bone marrow cells of mice with a genetic label, or barcode, researchers were able to track and describe the family tree of individual blood cells as they form in their natural environment. The scientists discovered that these cells regenerate differently than their counterparts do after a blood cell […]

Penn Engineers: Bone Marrow Transplant Stem Cells Can 'Swim' Upstream

When a cancer patient receives a bone marrow transplant, time is of the essence. Healthy stem cells, which can restart the production of blood cells and immune system components after a patient’s own are compromised, need to make their way from the circulatory system into the bones as quickly as […]

Unraveling the mechanisms that control cell growth and size

All living cells, from simple yeasts to human brain cells, regulate their rate of growth and their ultimate size and shape. How they do this, however, is one of the fundamental mysteries of biology. A new study, published in Current Biology, reveals a complex network of signals and feedback loops that control […]

Regrowing Limbs Could be the Future for Military Medicine

For some animals, such as salamanders, regrowing a missing limb is a common healing process. But what if people could do the same? Could the future of treating amputations include warfighters regrowing their own muscle, bone, and nerve tissues? “We’re not quite there yet,” said Army Lt. Col. David Saunders, […]

How a tumor grows can predict response to cancer therapy

Individual tumors respond differently to cancer drugs, if at all. Until now, it remained a mystery why tumors have different reactions to the exact same therapy. But a new study at the USC Viterbi School of Engineering finds that tumor growth properties can influence response to cancer drugs. “Identifying a […]
