ALS is caused by the accumulation of misfolded protein that eventually leads to neuronal cell death....
ALS is caused by the accumulation of misfolded protein that eventually leads to neuronal cell death. Just as is the case with prion diseases (e.g., Mad Cow disease), there is a spreading effect: even the presence of a small amount of misfolded (e.g., mutant) protein can cause other WT proteins of the same kind to become misfolded, which join the large misfolded aggregate forming in diseased cells. This is the principle mechanism thought to be behind the spreading of neurodegeneration...

You want to track translation of your transcription factor within a pancreatic cell for your Excellence...
You want to track translation of your transcription factor within a pancreatic cell for your Excellence in Research project. You perform a pulse-chase experiment, where radioactive amino acids are introduced to the cell over a short period of time (pulse) and then are washed away (chase). The radioactive amino acids will be introduced into newly synthesized protein and you can track the radioactive proteins as they are sorted throughout the cell. You also add a drug that prevents translation of...
