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 […]

UCLA scientists make cells that enable the sense of touch

Researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have, for the first time, coaxed human stem cells to become sensory interneurons — the cells that give us our sense of touch. The new protocol could be a step toward stem cell–based therapies to […]

Proteomics analyses could present new opportunities to diagnose and treat dementias

In the nervous system, a synapse is the place where signals are passed from neuron to neuron. The recently published paper focuses on synaptic dysfunction and its impact on dementia severity and cognition in the elderly with various dementia diagnoses. In addition to Alzheimer´s disease, the Lewy body dementias are the […]

New study offers added hope for patients awaiting corneal transplants

New national research led by Jonathan Lass of Case Western Reserve University School of Medicine has found that corneal donor tissue can be safely stored for 11 days before transplantation surgery to correct eye problems in people with diseases of the cornea. This is four days longer than the current […]

Cracking Tumor Defiance

Why does immunotherapy achieve dramatic results in some cancer patients but doesn’t help others? It is an urgent and vexing question for many cancer specialists. Now, two research groups from Harvard Medical School based at Dana-Farber Cancer Institute have independently discovered a genetic mechanism in cancer cells that influences whether […]

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. […]

New stem cell method sheds light on a telltale sign of heart disease

While refining ways to grow arterial endothelial cells in the lab, a regenerative biology team at the Morgridge Institute for Research at the University of Wisconsin–Madison unexpectedly unearthed a powerful new model for studying a hallmark of vascular disease. The team, led by Morgridge Institute Fellow Dave Vereide, describes in the Jan. 9, […]

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 […]

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 […]
