Traditional techniques consist of exposing the cells to drug or compounds that affect protein production, thereby creating instability. Renaud Geslain, a researcher in Ribas' group and first author of the article, "had a brilliant idea to reproduce the same effect within the cell, without the help of compounds alien to the cell," recalls Ribas. Geslain manipulated a component of the cellular protein synthesis machinery that causes the production of defective proteins. "In response to the accumulation of misfolded proteins, the cellular alarm systems are switched on and stress responses are activated. Given that this approach affects all the proteins, we obtain all the reactions possible, not only responses that could be exclusive to one or a few affected proteins."
