  • Patent number: 8426136
    Abstract: The invention provides a method for determining sensitivity of a cell population to apoptosis induced by Smac mimetics as a single agent or in combination with other chemodrugs, which method comprises assaying for an epigenetic modification at the TNF? locus in the cell population as compared to the TNF? locus in a cell population not sensitive to apoptosis induced by Smac mimetics as a single agent or in combination with other chemodrugs, wherein the presence of the epigenetic modification indicates that the cell population is sensitive to apoptosis induced by Smac mimetics as a single agent or in combination with other chemodrugs.
