'RNA sponge' mechanism may cause ALS/FTD neurodegeneration
The most common genetic cause of both ALS (amyotrophic lateral sclerosis) and FTD (frontotemporal dementia) was recently identified as an alteration in the gene C9orf72. But how the mutation causes neurodegenerative disease ...

Same signaling enzymes can trigger two different processes in the cell
Stroke, heart attacks and numerous other common disorders result in a massive destruction of cells and tissues called necrosis. It's a violent event: As each cell dies, its membrane ruptures, releasing substances that trigger ...

Cancer suppressor gene links metabolism with cellular aging
The tumor suppressor protein p53 is an attractive target for drug developers. But this path has so far proven difficult, as most p53 regulatory proteins operate via protein-protein interactions, which make for poor drug targets, ...
