The research also has great relevance for patients on Earth who are immobilized for long periods –?paraplegics, quadriplegics, and people in casts, says Long's mentor for the project, SFVAMC staff physician Daniel D. Bikle, MD, PhD, a professor of medicine and dermatology at UCSF. As ...

New molecular pathway could reveal how cells stick together

...re, then you want to go back and demonstrate their relevance to the animal." To study the role of ninjurin in development and immunity, Page-McCaw uses a strategy to exclude the protein from the animal. By developing a mutant fly lacking the gene that codes for the protein, she can examine what goes wrong w...

New insights into autoimmunity and depression

...pathways are similarly affected in humans. "The relevance of the results to the involvement of the central nervous system in SLE is another intriguing aspect of the present study," notes its leading author, Yehuda Shoenfeld, M.D., while emphasizing the need for further investigation through large-scale clin...

Cloned mice created from fully differentiated cells, a milestone in cloning research

...owever, of particular interest to Dr. Cheng is the relevance of their findings to cancer stem cell research. "An interesting question to me is whether SCNT can play a role in understanding or even reprogramming the behavior of cancer stem cells. Such studies may potentially reveal a new set of molecular targ...

Key to acute lung injury lies in Ang2 protein

...reates lung injury and then we showed its clinical relevance by documenting its presence in human patients with acute lung injury." In addition to acute lung injury and pulmonary edema, Bhandari said, an increase in Ang2 and cell death can be seen in other disorders such as heart attacks, stroke, eye diseas...

Effective HIV control may depend on viral protein targeted by immune cells

... responses on the ability to control HIV has clear relevance to vaccine development," says Goulder, who is an associate professor of Medicine at Harvard Medical School....

Dragonfly's metabolic disease provides clues about human obesity

...to think that our dragonfly results might have any relevance for human disease, but it would be irresponsible for us to not point out these possibilities. People who study metabolic disease should test the hypothesis that changes in gut microbial composition can cause these syndromes." __IMAGE_3 Marden'...

... research project has consequently acquired direct relevance to medicine. "What we see in our neuroligin mutants is a more intensified form of the malfunction that occurs in the brain of autistic people," says Brose. "I believe that autism is a disease of the synapses, a synaptopathy." The Max Planck researche...

New mechanism explains glucose effect on wakefulness

...als has never been tested, the daily physiological relevance of their glucose sensing is also unknown." In their experiments, the researchers engineered mice to produce a fluorescent protein only in orexin neurons. Thus, the researchers could isolate the neurons in brain slices from the mice and perform preci...
