Mechanism for the inducible apoptosis of senescent cells in INK-ATTAC mice. Zygotic cells are transfected with a construct encoding an FKBP/Casp8 complex plus a green fluorescent protein, all under the control of the Ink4a/Arf promoter (active only in senescent cells). Administration of the dimerizer AP20187 leads to conformation of an active caspase-8 and selective apoptosis of senescent cells in the whole organism. FKBP FK506 binding protein, IRES internal ribosomal entry site, GFP green fluorescent protein
