In prospective trials, the cyclooxygenase inhibitor aspirin (acetylsalicylic acid) reduced the risk of AD and PD, as well as cardiovascular events and many late-onset cancers. Considering the role played by protein hyperphosphorylation in aggregation and neurodegenerative diseases, and aspirin's known ability to donate acetyl groups, we asked whether aspirin might reduce both phosphorylation and aggregation by acetylating protein targets.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Aspirin was substantially more effective than salicylate in reducing or delaying aggregation in human neuroblastoma cells grown\n                      <jats:italic toggle=\"yes\">in vitro<\/jats:italic>\n                      , and in\n                      <jats:italic toggle=\"yes\">Caenorhabditis elegans<\/jats:italic>\n                      models of human neurodegenerative diseases\n                      <jats:italic toggle=\"yes\">in vivo.<\/jats:italic>\n                      Aspirin acetylates many proteins, while reducing phosphorylation, suggesting that acetylation may oppose phosphorylation. Surprisingly, acetylated proteins were largely excluded from compact aggregates. Molecular-dynamic simulations indicate that acetylation of amyloid peptide energetically disfavors its association into dimers and octamers, and oligomers that do form are less compact and stable than those comprising unacetylated peptides.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Innovation:<\/jats:title>\n                    <jats:p>\n                      Hyperphosphorylation predisposes certain proteins to aggregate (\n                      <jats:italic toggle=\"yes\">e.g.,<\/jats:italic>\n                      tau, \u03b1-synuclein, and transactive response DNA-binding protein 43 [TDP-43]), and it is a critical pathogenic marker in both cardiovascular and neurodegenerative diseases.
