Project description:A mutant screen was conducted in Arabidopsis that was based on deregulated expression of auxin-responsive transgenes. Two different tightly regulated (i.e., very low expression in the absence of auxin treatment and very high expression after exogenous auxin treatment) auxin-responsive promoters were used to drive the expression of both a ?-glucuronidase (GUS) reporter gene and a hygromycin phosphotransferase (HPH)?selectable marker gene. This screen yielded several mutants, and five of the mutations (axe1-1 to axe1-5) mapped to the same locus on chromosome 5. A map-based cloning approach was used to locate the axe1 mutations in an Arabidopsis RPD3-like histone deacetylase gene, referred to as HDA6. The axe1 mutant plants displayed increased expression of the GUS and HPH transgenes in the absence of auxin treatment and increased auxin-inducible expression of the transgenes compared with nonmutant control plants. None of a variety of endogenous, natural auxin-inducible genes in the mutant plants were upregulated like the transgenes, however. Results of treatment with the DNA methylation inhibitor 5-aza-2'-deoxycytidine suggest that the axe1 mutations affect transgene silencing; however, histone deacetylase inhibitors had no affect on transgene silencing in mutant or control plants. The specific effect of AtHDA6 mutations on the auxin-responsive transgenes implicates this RPD3-like histone deacetylase as playing a role in transgene silencing. Furthermore, the effect of AtHDA6 on transgene silencing may be independent of its histone deacetylase activity. *

Project description:Although the Arabidopsis thaliana RPD3-type histone deacetylases have been known to form SIN3 histone deacetylase complexes that are conserved in eukaryotes, it is unknown whether they also form other types of histone deacetylase complexes. Here, we performed affinity purification followed by mass spectrometry and demonstrated that the Arabidopsis RPD3-type histone deacetylases HDA6 and HDA19 can interact with several previously uncharacterized proteins and form three types of plant-specific histone deacetylase complexes, which we named SANT, ESANT, and ARID. RNA-seq indicated that HDA6 and HDA19 function together with other components of the histone deacetylase complexes and co-regulate the expression of a number of genes. HDA6 and HDA19 have been thought to repress gene transcription by histone deacetylation. We found that the histone deacetylase complexes can also repress gene expression via certain histone-deacetylation-independent mechanisms. In the mutants of the histone deacetylase complexes, the expression of a number of stress-induced genes was up-regulated. Several mutants of the histone deacetylase complexes showed severe retardation in growth. Considering that the growth retardation is thought to be a trade-off for the increase of stress tolerance, we predict that the histone deacetylase complexes identified in this study prevent overexpression of stress-induced genes and thereby ensure normal growth of plants under non-stress conditions.

Project description:Histone deacetylase (HDAC) inibitors suppress cell proliferation of prostate cancer, but the detailed mechanisms are unknown. Moreover, HDAC includes 18 family members, namely HDAC1-11 and SIRT1-7, and differences of effects on prostate cancer proliferation among these enzymes are also unknown. Thus, we clarified differences of gene expression between prostate cancer cell line (LNCaP) treated with pan-HDAC inhibitors (TSA and OBP-801) or selective HDAC inhibitor (NCC-149, HDAC8-specific inhibitor)using cDNA microarray. LNCaP treated with TSA (1μM), NCC149 (2μM), OBP-801 (200nM) or DMSO for 24hrs, RNA was extracted from cells, and cDNA array was performed.

A replicate experimental design type is where a series of replicates are performed to evaluate reproducibility or as a pilot study to determine the appropriate number of replicates for a subsequent experiments.
