To get more insight into the biological functions of the individual HDAC family members, we have used RNA interference in combination with microarray analysis in Drosophila S2 cells. Silencing of Drosophila HDAC1 (DHDAC1), but not of the other DHDAC family members, leads to increased histone acetylation. Silencing of either DHDAC1 or DHDAC3 leads to cell growth inhibition and deregulated transcription of both common and distinct groups of genes. Silencing DHDAC2 leads to increased tubulin acetylation levels but was not associated with a deregulation of gene expression. No growth of phenotype and no significant deregulation of gene expression was observed upon silencing of DHDAC4 and DHDACX. Loss of DHDAC1 or exposure of S2 cells to the small molecule HDAC inhibitor trichostatin both lead to a G(2) arrest and were associated with significantly overlapping gene expression signatures in which genes involved in nucleobase and lipid metabolism, DNA replication, cell cycle regulation, and signal transduction were over-represented. A large number of these genes were shown to also be deregulated upon loss of the co-repressor SIN3 (Pile, L. A., Spellman, P. T., Katzenberger, R. J., and Wassarman, D. A. (2003) J. Biol. Chem. 278, 37840-37848). We conclude the following. 1) DHDAC1 and -3 have distinct functions in the control of gene expression. 2) Under the tested conditions, DHDAC2, -4, and X have no detectable transcriptional functions in S2 cells. 3) The anti-proliferative and transcriptional effects of trichostatin are largely recapitulated by the loss of DHDAC1. 4) The deacetylase activity of DHDAC1 significantly contributes to the repressor function of SIN3."xsd:string |
