ASSAYS FOR COMPOUNDS WHICH EXTEND LIFE SPAN

摘要

Methods of identifying agents or compounds which are capable of inhibiting the replication and/or accumulation of DNA circles in cells are described. Also described are methods of assessing the ability of a compound to extend life span, as well as methods of extending life span, comprising administering to a cell a compound identified by the assays described herein which extends life span. The invention also pertains to isolated mWRN, or an active derivative or fragment thereof and to an isolated nucleic acid molecule which encodes mWRN, or an active derivative or fragment thereof.
