Humans and their pet dogs are close, so close that they both develop a type of cancer called diffuse large B-cell lymphoma. In humans it's the most common lymphoma subtype while in dogs, it's one of the most common cancers in veterinary oncology. Now, a study comparing canine and human B-cell lymphoma has found molecular similarities between the cancers, allowing researchers to better understand the origins of the disease in both species.

Vampire bat venom could prove the key ingredient in future medication for stroke and high blood pressure after an international team of scientists identified ''a whole suite'' of ways bats prevent blood from clotting.

Researchers at Duke Medicine have found a way to prevent epilepsy in mice that have already experienced a long period of seizures--a feat that could help scientists develop new drugs to treat the serious neurological disorder.

Exercise can lead to more regular sleep patterns, an improved immune system, better brain function and a longer life, research suggests.

Glasgow University scientists found that old mice took longer to adapt to changes to their daily routine, but that their synchronisation improved if they had access to a running wheel.

Researchers have known for some time that stem cells are capable of producing new cells, but the new study shows how a select group of stem cells can create progenitors that then generate numerous subtypes of cells.

Studies in zebrafish reveal abundant potential source for repair of injured heart muscle.

A study of wild mice, which typically carry several parasitic infections at a time, finds treating one infection may worsen another.

In what CSU is calling the most realistic study of its kind, scientists are hoping to better understand how tuberculosis is transmitted, thanks in part to humans infected with the killer disease and hundreds of guinea pigs.

Scientists commonly use just four species to investigate the basic processes shared by all living creatures. Tom Shakespeare explains how the fruit fly, the zebra fish, the roundworm and the mouse found themselves at the forefront of scientific research.

Researchers at UC Berkeley have developed an easier and more effective method for inserting genes into eye cells that could greatly expand gene therapy to help restore sight to patients with blinding diseases ranging from inherited defects like retinitis pigmentosa to degenerative illnesses of old age, such as macular degeneration. The engineered virus works far better than current therapies in rodent models of two human degenerative eye diseases, and can penetrate photoreceptor cells in monkeys’ eyes, which are like those of humans.

Working with mice, researchers led by Mayumi Ito at New York University have identified a population of stem cells lying beneath the base of the nail that can orchestrate the restoration of a partially amputated digit.

A team of NIH-supported researchers is the first to show, in mice, an unexpected two-step process that happens during the growth and regeneration of inner ear tip links. Tip links are extracellular tethers that link stereocilia, the tiny sensory projections on inner ear hair cells that convert sound into electrical signals, and play a key role in hearing. The discovery offers a possible mechanism for potential interventions that could preserve hearing in people whose hearing loss is caused by genetic disorders related to tip link dysfunction.

The mouse hospital at Beth Israel Deaconess and a few similar ones elsewhere are at the forefront of a new approach to studying human cancers. The mice are given genes that make them develop tumors in the same organs as humans, which means the researchers need scanners to watch the tumors’ growth inside the animals’ bodies. So the mouse hospitals have tiny ultrasound machines, CT and PET scanners, and magnetic resonance imaging machines with little stretchers to slide the mice into the machines. They also have mouse pharmacies to formulate medicines in mouse-size doses and mouse clinical laboratories specially designed to do analyses on minute drops of mouse blood and vanishingly small quantities of mouse urine. That lets them follow cancers’ growth and responses to treatments.

Animal studies indicate that delivering chemotherapy through inhalation significantly improves the rate of successfully treating lung tumors.

N.C. State University and Yale University researchers uncovered the developmental pathway to one frog species’ carnivorous diet – helping us to understand our own guts in the process.

The master and his dog are both very nervous. On a Thursday morning in April, Randy Wildebrandt has brought Jazzy, a black, 14-year-old poodle, to the MU veterinary hospital for an examination of a cancerous tumor on her right hind leg. She will be injected with a radioactive liquid for a PET, or positron emission topography scan to determine whether her treatment is shrinking the tumor, then she'll spend a day in isolation while the radiation wears off. Jazzy is one of several dogs receiving experimental treatments through the comparative oncology program at MU. Veterinarians hope they can examine the dogs' responses to the treatments to learn new ways of fighting cancer in humans.

If you prod a zebrafish embryo, it will normally twitch its tail and try to escape. By watching embryos that wouldn’t twitch properly, a team of scientists has discovered that a gene called STAC3is the cause of a rare inherited muscle disorder called Native American myopathy (NAM). The team also showed that STAC3 plays an important and previously unrecognized role in muscle contractions.

Scientists at the National Institutes of Health, and their colleagues, have discovered that a gene called BACH2 may play a central role in the development of diverse allergic and autoimmune diseases, such as multiple sclerosis, asthma, Crohn's disease, celiac disease, and type-1 diabetes. In autoimmune diseases, the immune system attacks normal cells and tissues in the body that are generally recognized as “self” and do not normally trigger immune responses. Autoimmunity can occur in infectious diseases and cancer.

Researchers at the Perelman School of Medicine, University of Pennsylvania have developed a new gene therapy to thwart a potential influenza pandemic. Specifically, investigators in the Gene Therapy Program, Department of Pathology and Laboratory Medicine, directed by James M. Wilson, MD, PhD, demonstrated that a single dose of an adeno-associated virus (AAV) expressing a broadly neutralizing flu antibody into the nasal passages of mice and ferrets gives them complete protection and substantial reductions in flu replication when exposed to lethal strains of H5N1 and H1N1 flu virus. These strains were isolated from samples associated from historic human pandemics – one from the infamous 1918 flu pandemic and another from 2009.
