Trojan Horses, xenon imaging and remote controlled genes

...ane, it can become a sensitive reporter of changes outside the cage. When the cage is "rattled" by a specific cancer protein, for example, the xenon molecule will emit a telltale signal that can be tracked by MRI. "Based on this principle, our lab is generating new biosensors that we hope will identify bio...

But, Sirkar speculated, will it work if the mixtures contain three or four proteins? More questions include: can it be used on viruses or endo...

Study suggests cell-cycle triggers might be cancer drug targets

... cyclins is a linking one. They respond to signals outside the cell and turn the cell-cycle machinery on when needed, enabling the cell to adjust to changes in environment. How this process is carried out in the mouse embryos with no D-type cyclins is a puzzle, says Sicinski who is also an associate professo...

Researchers report new gene test for isolated cleft lip and palate

...hey identified a total of 36 SNPs, both inside 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 contributin...

Newly discovered protein may be key to muscular dystrophy

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 genetic screen, the scientists ...
