the cell. This treatment impaired dendrite growth, "which gives us hints that there is a signaling pathway within the cell activated by Dasm1 that we need to explore," she said. The next step, the researchers say, is to knock out the Dasm1 gene in m...
Common cold virus can cause polio in mice when injected into muscles
...th Coxsackievirus facilitated its unusual behavior inside
the body, the study showed. The mice were injected with Coxsackievirus into their calf muscles, an unusual route of entry. Following the injection, the mice began to display symptoms of polio, including an abnormal gait, dropfoot, and lower hind limb...
Bone marrow cells routinely help with wound healing
... bone marrow of the transplanted mice glowed green inside
the bodies of the mice, allowing researchers to track the bone marrow cells throughout the body. Researchers found green cells throughout the body, but observed that the highest concentration of bone marrow cells was in normal skin. That was a surpr...

its cell. Engineers have exploited this capability to remove excess phosphorus--from fertilizers and detergents--from wastewater. Too much phosphorous can over-stimulate microbial growth resulting in eutrophication, where oxygen in the water is depl...
First clinical study of new pediatric croup vaccine shows safety, tolerability in adults

the body. The vaccine consists of Sendai virus (SeV), a mouse virus that is similar enough to hPIV-1 to act as a vaccine, but different enough to have never been associated with a human disease, according to Karen Slobod, M.D., associate member of t...

and outside the gene, and nine of these variations seemed to be associated with clefting. "These individual variations, or SNPs can be assembled into a haplotype," said Mary Marazita, Ph.D., a statistician at the University of Pittsburgh and a major...
Newly discovered protein may be key to muscular dystrophy

the cell to the region outside of the cell. The complex is found in C. elegans, in mice and in humans. In each species, defects in the complex can cause muscle degeneration, but the exact role of the complex in disease has not been clear. In a ...
New 'clock gene' uncovered
...Rora protein plays a role in the circadian rhythms inside
a living creature. They observed a mutant murine model that has a defective Rora gene. This murine model is called "staggerer" because its genetic defect causes a characteristic loss of coordination. As it turns out, the staggerer model with a d...

the eye to rise. When this happens, the optic nerve in the back of the eye can become squeezed. As this is the area that carries the visual signals from eye to brain, vision loss can occur, Borrs said. In earlier studies, Borrs and her research ...
