A new study in rats is shedding light on how sleep-deprived lifestyles might impair functioning without people realizing it. The more rats are sleep-deprived, the more some of their neurons take catnaps — with consequent declines in task performance.

Gene therapy that uses a tiny benign virus to take a gene to the rods and cones of the eye's retina (the light-sensing organ) prevented blindness in mice with a genetic blinding syndrome, said researchers from Baylor College of Medicine in an online report of the Proceedings of the National Academy of Sciences.

In the first animal model of Amyotrophic Lateral Sclerosis (ALS), developed by Dr. Udai Pandey, Assistant Professor of Genetics at LSU Health Sciences Center New Orleans, Dr. Pandey's lab has found in fruit flies that blocking the abnormal movement of a protein made by a mutated gene called FUS also blocks the disease process.

It's a conflict with no resolution in sight. On one side, scientists who experiment on animals. On the other, animal rights activists who believe that no animal should ever be harmed. But how far can activists go before their right to free speech threatens the scientists and their work?

An experimental drug that blocks two points of a crucial cancer cell signaling pathway inhibits the growth of ovarian cancer cells and significantly increases survival in an ovarian cancer mouse model, a study at UCLA's Jonsson Comprehensive Cancer Center has found.

Adult mice engineered to have more newborn neurons in their brain memory hub excelled at accurately discriminating between similar experiences — an ability that declines with normal aging and in some anxiety disorders. Boosting such neurogenesis in the adult hippocampus also produced antidepressant-like effects when combined with exercise, in the study funded by the National Institutes of Health.

Researchers at North Carolina State University are narrowing the search for genes involved in non-Hodgkin lymphoma – by turning dogs into humans. Humans and dogs don’t just share companionship and living space, they also share a similar genetic makeup. Additionally, they share the same types of cancer, including lymphoma.

Researchers at Mount Sinai School of Medicine have discovered a way that mutations in a gene called LRRK2 may cause the most common inherited form of Parkinson's disease. The study, published online this month in the journal Public Library of Science, shows that upon specific modification called phosphorylation, LRRK2 protein binds to a family of proteins called 14-3-3, which has a regulatory function inside cells.

By sequencing the genome of a mouse with cancer, researchers at Washington University School of Medicine in St. Louis have uncovered mutations that also drive cancer in humans.

A new study of prostate tumors has shown that a gene, FOXO3, suppresses activation of cells related to immunity and thus leads to a reduced immune response against a growing cancer. One of the main problems in treating cancer by vaccine or immunotherapy is that tumors often evade the body’s immune response — and one of their tricks is to create an environment where immunity is inhibited or suppressed.
