Scientists identify molecular cause for one form of deafness

...undles of protein filaments within the hair cells, impairing the passage of vibrations and resulting in deafness. Filamentous actin (F-actin) is a rod-like protein that provides structural framework in living cells. F-actin is organized into bundles by espin, a linker protein found in sensory cells, includin...

"It is already known that there is paradoxical dose-dependent effect of nicotine on ovarian tissue. Maybe the same effect is happening in uterine tissue. The effect of a certain molec...

MIT research holds promise for Huntington's treatment

...lar proteins accumulate, poisoning brain cells and impairing patients' motor and cognitive function. Until now, most researchers looking for Huntington's treatments have focused on compounds that prevent or reverse the aggregation of huntingtin proteins. However, recent evidence suggests that the largest incl...

Anthrax stops body from fighting back, study shows

... as the body's first defense against infection, by impairing how they build tiny filaments that allow them to ...d. This led researchers to believe anthrax may be impairing the cells' ability to move and fight off the offending bacteria, an idea that hadonly been studied o...

Brain size may depend upon how neural cells are cleaved

... the effects in vitro. Those studies revealed that impairing Gβγ did result in overproduction of neurons as a result of both daughter cells adopting the neuronal fate. Thus, the researchers concluded that Gβγ does control the orientation of cleavage and the identity of the daughter cells -- whether they will b...
