title: HDAC3 is linked to cell cycle machinery in MiaPaCa2 cells by regulating transcription of skp2.
abstract: OBJECTIVE
  Histone deacetylases (HDACs) have been linked to cell cycle control in various models, involving regulation of the cyclin-dependent kinase inhibitor p27(Kip1).
  
  
  RESULTS
  Here, we demonstrate that HDAC inhibition by trichostatin A reduces S-phase kinase-associated protein 2 mRNA and protein abundance. Furthermore, in contrast to HDAC1, recruited to the skp2 promoter in the G(0) phase, HDAC3 is bound in early S phase. Activating function of HDAC3 towards the skp2 gene has been validated using RNA interference techniques. siRNAs, targeting HDAC3 specifically, reduced skp2 transcription.
  
  
  CONCLUSIONS
  These findings propose that the skp2 gene is a novel target of HDAC3, mediating cell cycle control and oncogenesis.
