Transcriptional repression mediated by corepressors N-CoR and SMRT is a critical function of nuclear hormone receptors, and is dysregulated in human myeloid leukemias.

|
Surprisingly, however, numerous biochemical studies have not detected N-CoR or SMRT in mSin3- and HDAC1-containing complexes.

|
Here we show that these RDs are nonredundant, and that one RD, which is conserved in N-CoR and SMRT, represses transcription by interacting directly with class II HDAC4 and HDAC5.

Endogenous N-CoR and SMRT each associate with HDAC4 in a complex that does not contain mSin3A or HDAC1.

Overexpression of GLUT4 in skeletal muscle enhances whole-body insulin action.

|
Exercise increases GLUT4 gene and protein expression, and a binding site for the myocyte enhancer factor 2 (MEF-2) is required on the GLUT4 promoter for this response.

|
In various cell systems, MEF-2 regulation is a balance between transcriptional repression by histone deacetylases (HDACs) and transcriptional activation by the nuclear factor of activated T-cells (NFAT), peroxisome proliferator-activated receptor-gamma coactivator 1 (PGC-1), and the p38 mitogen-activated protein kinase.

After exercise, HDAC5 was dissociated from MEF-2 and exported from the nucleus, whereas nuclear PGC-1 was associated with MEF-2.
|

|
Exercise increased total and nuclear p38 phosphorylation and association with MEF-2, without changes in total or nuclear p38 protein abundance.
|
10 |

|
This result was associated with p38 sequence-specific phosphorylation of MEF-2 and an increase in GLUT4 mRNA.
|
11 |

|
From these data, it appears that HDAC5, PGC-1, and p38 regulate MEF-2 and could be potential targets for modulating GLUT4 expression.

Glucose transporter isoform 4 gene expression is increased immediately following a single bout of exercise, and the GLUT-4 enhancer factor (GEF) and myocyte enhancer factor 2 (MEF2) transcription factors are required for this response.

These studies find possible roles for histone deacetylase 5 (HDAC5), adenosine monophosphate-activated protein kinase (AMPK), peroxisome proliferator-activated receptor gamma coactivator 1alpha (PGC-1alpha) and p38 mitogen-activated protein kinase (MAPK) in regulating MEF2 through a series of complex interactions potentially involving MEF2 repression, coactivation and phosphorylation. 4.

It has been shown that HDAC4 and 5 co-operatively regulate a number of genes involved in various aspects of metabolism.

|
The HDACs are also regulated by ubiquitin-mediated proteasomal degradation, although the exact mediators of this process have not been identified. 5.
|
25 |

|
Together, these data show that HDAC4 and 5 are critical regulators of metabolic gene expression and that understanding their regulation could provide a number of points of intervention for therapies designed to treat metabolic diseases, such as insulin resistance, obesity and Type 2 diabetes.

Involvement of p300/CBP and epigenetic histone acetylation in TGF-β1-mediated gene transcription in mesangial cells.

Transforming growth factor-β1 (TGF-β1)-induced expression of plasminogen activator inhibitor-1 (PAI-1) and p21 in renal mesangial cells (MCs) plays a major role in glomerulosclerosis and hypertrophy, key events in the pathogenesis of diabetic nephropathy.
|

|
We evaluated the roles of histone acetylation, specific HATs, and HDACs in TGF-β1-induced gene expression in rat mesangial cells (RMCs) and in glomeruli from diabetic mice.
|
33 |

|
Overexpression of HATs CREB binding protein (CBP) or p300, but not p300/CBP-activating factor, significantly enhanced TGF-β1-induced PAI-1 and p21 mRNA levels as well as transactivation of their promoters in RMCs.
|
34 |

|
Conversely, they were significantly attenuated by HAT domain mutants of CBP and p300 or overexpression of HDAC-1 and HDAC-5.

Chromatin immunoprecipitation assays showed that TGF-β1 treatment led to a time-dependent enrichment of histone H3-lysine9/14-acetylation (H3K9/14Ac) and p300/CBP occupancies around Smad and Sp1 binding sites at the PAI-1 and p21 promoters.
|
36 |
23235480
|
TGF-β1 also enhanced the interaction of p300 with Smad2/3 and Sp1 and increased Smad2/3 acetylation.
|
37 |
23235480
|
High glucose-treated RMCs exhibited increased PAI-1 and p21 levels, and promoter H3K9/14Ac, which were blocked by TGF-β1 antibodies.
|
38 |
23235480
|
Furthermore, increased PAI-1 and p21 expression was associated with elevated promoter H3K9/14Ac levels in glomeruli from diabetic mice.
|
39 |
23235480
|
Thus TGF-β1-induced PAI-1 and p21 expression involves interaction of p300/CBP with Smads and Sp1, and increased promoter access via p300/CBP-induced H3K9/14Ac.
