Essential Protein Needed for Fertilization

April 17, 2014 | by Wellcome Trust Sanger Institute | Comments

Researchers have discovered interacting proteins on the surface of the sperm and the egg essential to begin mammalian life. These proteins, which allow the sperm and egg to recognize one another, offer new paths towards improved fertility treatments and the development of new contraceptives.

Mouse Model Would Have Predicted Toxicity of Fatal Drug

April 16, 2014 12:22 pm | by PLOS | Comments

Over 20 years after the fatal fialuridine trial, a study demonstrates that mice with humanized livers recapitulate the drug's toxicity.

Why Does Eating Less Increase Life Span?

April 16, 2014 12:05 pm | by Annie Sneed, Scientific American | Comments

Nematode worms, fruit flies, mice and other lab animals live longer, healthier lives when they eat less than they otherwise would if more food were available. Researchers have declared the most popular theory doesn’t make evolutionary sense, and they’ve proposed a new explanation in its place.

'3D' Model Could Reduce Animal Testing of Asthma and Allergy Medications

April 16, 2014 9:40 am | by American Chemical Society | Comments

Scientists report that they’ve developed a simple, “3D” laboratory method to test asthma and allergy medications that mimics what happens in the body, which could help reduce the need for animal testing.             

Researchers Transplant Regenerated Esophagus in Rats

April 15, 2014 2:09 pm | by Karolinska Institutet | Comments

Tissue engineering has been used to construct natural esophagi, which in combination with bone marrow stem cells have been safely and effectively transplanted in rats.

Reversing Alzheimer's Symptoms in Mice

April 15, 2014 1:55 pm | by Deborah Halber, MIT | Comments

Limiting a certain protein in the brain reverses Alzheimer’s symptoms in mice. Researchers found that the overproduction of the protein known as p25 may be the culprit behind the sticky protein-fragment clusters that build up in the brains of Alzheimer's patients.

Age Matters for Regenerating Muscle in Duchenne MS Models

April 15, 2014 1:29 pm | by Susan Gammon, Sanford-Burnham Medical Research Institute | Comments

A team of scientists have published details of how a class of drugs called “HDACis” drive muscle-cell regeneration in the early stages of dystrophic muscles, but fail to work in late stages.

Stress Damage Blocked in Mice

April 14, 2014 2:08 pm | by Bill Hathaway, Yale Univ. | Comments

Ketamine, an anesthetic sometimes abused as a street drug, increases the synaptic connections between brain cells and in low doses acts as a powerful antidepressant. However, stress has the opposite effect, shrinking the number of synaptic spines, triggering depression.

Kidney Regeneration Linked to Gene Found in Mice

April 14, 2014 1:50 pm | by Boston Children's Hospital | Comments

Mice engineered to express Lin28 in their kidneys developed Wilms tumor, which regressed when Lin28 was withdrawn, indicating that strategies aimed at blocking or deactivating the gene hold therapeutic promise for children with Wilms.
