Project description:Sirtuins (Sirt) are a family of enzymes that modify chromatin and other proteins to affect gene activity. Loss of Sirt6 leads to a progeria-like phenotype in mice, but the target of SIRT6 action has been elusive. Here we show that Sirt6 binds to thousands of gene promoters in a stress-inducible fashion, guided by the stress-responsive transcription factor NF-κB. Chromatin profiling by ChIP-chip analysis of Sirt6 and NF-KB component RelA combined with expression array data of wildtype, Sirt6 knockout and Sirt6 RelA double knockout cells demonstrates that RelA recruits Sirt6 to NF-KB targets in response to TNF-a induction and that many of these targets are important for senescence and aging. comparison of wild type, Sirt6-/- and Sirt6-/- RelA-/- MEF cells

Loss of Sirt6 leads to a progeria-like phenotype in mice, but the target of SIRT6 action has been elusive. Here we show that Sirt6 binds to thousands of gene promoters in a stress-inducible fashion, guided by the stress-responsive transcription factor NF-?B. Chromatin profiling by ChIP-chip analysis of Sirt6 and NF-KB component RelA combined with expression array data of wildtype, Sirt6 knockout and Sirt6 RelA double knockout cells demonstrates that RelA recruits Sirt6 to NF-KB targets in response to TNF-a induction and that many of these targets are important for senescence and aging. comparison of wild type, RelA -/- and Sirt6-/- MEF cells

Project description:We harvested spleen tissue from Sirt6-/- or Sirt6-/- RelA+/- animals and then completed genome-wide microarray analysis. Total RNA was extracted with TRIzol (Invitrogen) and amplified with Amino Allyl MessageAmp II Amplification kit. Amplified age-matched wild-type tissues were used as reference RNA for analysis. Array hybridization of mouse MEEBO arrays is as described (Hendrickson et al., PLoS ONE, 2008).
