  • Patent number: 9358249
    Abstract: In certain embodiments this invention pertains to the discovery that inhibition of the expression and/or activity of eukaryotic initiation factor 4A (eIF4A) inhibits the aging process. Accordingly, in certain embodiments, methods are provided for inhibiting/slowing aging. The methods typically involve administering to a mammal an agent that inhibits the expression and/or activity of eukaryotic initiation factor 4A (eIF4A) in an amount sufficient to inhibit expression or activity of EIF4A, where the agent is not resveratrol.

  • Patent number: 8703438
    Abstract: Drug affinity responsive target stability (DARTS) is a method of drug target ID with several significant advantages over current techniques. In certain embodiments the method involves contacting a sample comprising one or more protein target(s) with a test agent to form a sample/test agent mixture; contacting the mixture with a protease; and identifying a protein or protein fragment that is protected from proteolysis, wherein the protection from proteolysis is an indicator that the protein or protein fragment binds to or interacts with the test agent.
