Long-lived proteins exist in a number of tissues in the human body; however, little is known about the reactions involved in their degradation over time. Lens proteins, which do not turn over, provide a useful system to examine such processes. Using a combination of Western blotting and proteomic methodology, age-related changes to a major protein,(More)
A number of mutant Chinese hamster ovary (CHO) cell lines resistant to the cytotoxic action of alpha-amanitin have been isolated. The alpha-amanitin sensitivity of the different mutant cell lines varied widely, but correlated well with the alpha-amanitin sensitivity of the RNA polymerase II activity in each of these mutant cell lines. In comparison with the(More)
