Many women struggling to have a baby turn to in-vitro fertilization to improve their chances, and then face further uncertainty and anxiety when confronted with the decision of whether to use frozen or fresh embryos. A new study by a researcher at Yale School of Public Health and co-authors in […]

Researchers at the Case Comprehensive Cancer Center (CCCC) at Case Western Reserve University have helped develop a computer program to find new indications for old drugs. The computer program, called DrugPredict, matches existing data about FDA-approved drugs to diseases, and predicts potential drug efficacy. In a recent study published in Oncogene, the […]

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 […]

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 […]

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 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 […]

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 […]

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. […]

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, […]

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 […]

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 […]

Cancer cells can be destroyed more effectively and selectively with a unique new reusable treatment, activated with a substance found in stinging nettles and ants – thanks to new research by the University of Warwick.  Cancer cells killed more effectively and selectively with a new approach, using a substance found […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

Scientists at the National Eye Institute (NEI), part of the National Institutes of Health, report that tiny tube-like protrusions called primary cilia on cells of the retinal pigment epithelium (RPE) — a layer of cells in the back of the eye  — are essential for the survival of the retina’s […]
