Study dusts sugar coating off little-known regulation in cells
In Alzheimer's disease, brain neurons become clogged with tangled proteins. Scientists suspect these tangles arise partly due to malfunctions in a little-known regulatory system within cells. Now, researchers have dramatically ...

Extensive protein interaction network controls gene regulation
The genes of a cell are like the 88 keys of a piano. To play chords and music, however, the keys must be activated in exact combinations by a pianist's hands. Those hands represent the coregulators of a cell that simultaneously ...

In Brief: Guiding cancer cells to their fate
It is often said that the best way to spur change is to work within the system. Here, researchers create control devices based on RNA, which can be used to synthetically rewire cellular behavior, making the cells more sensitive ...

'Runaway' development implicated in loss of function of the aging brain
The brain undergoes rapid growth and development in the early years of life and then degenerates as we progress into old age, yet little is known about the biological processes that distinguish brain development and aging. ...

New role for the JNK protein
Put simply, a tumor is the result of out-of-control cell growth. To assure that the cell cycle - the cell's process of duplicating itself to make more cells - goes smoothly, a large network of proteins tells other proteins ...
