The recent discovery of estrogen receptor beta as a biological partner with estrogen receptor alpha in mediating the estrogen response has come at precisely the same time as intensive research is revealing the role played by downstream coregulator proteins in linking nuclear hormone receptor activity to general transcription machinery involved in gene transcriptional activation.

In what is a rapidly evolving area of research, findings to date have led to a proposed model of hormonal action, in which a receptor activated by estrogen or cell-membrane-derived phosphorylation-dependent signaling pathways promotes recruitment of selected members of the multifunctional steroid receptor coactivator family and the cointegrators, p300/CBP and P/CAF.

On the other hand, antiestrogen-bound receptors favour the assembly of receptor-corepressor complexes containing the sequence-related corepressors N-CoR (nuclear receptor corepressor) or SMRT (silencing mediator of retinoid and thyroid hormone receptors), localizing histone deacetylase activity to the promoter and leading to transcriptional repression.

Pancreatic islets from HD transgenic mice express reduced levels of the pancreatic islet hormones insulin, somatostatin, and glucagon and exhibit intrinsic defects in insulin production.

|
HD transgenic mice develop an age-dependent reduction of insulin mRNA expression and diminished expression of key regulators of insulin gene transcription, including the pancreatic homeoprotein PDX-1, E2A proteins, and the coactivators CBP and p300.

Disrupted expression of a subset of transcription factors in pancreatic beta cells by a polyglutamine expansion tract in the huntingtin protein selectively impairs insulin gene expression to result in insulin deficiency and diabetes.

Its effects are optimized by various coactivators including histone acetyltransferases (HATs) such as CBP/p300 and p/CAF.

We therefore carried out chromatin immunoprecipitation (ChIP) assays in monocytes to identify 1) chromatin factors bound to the promoters of tumor necrosis factor-alpha (TNF-alpha) and related NF-kappaB-regulated genes under HG or diabetic conditions, 2) specific lysine (Lys (K)) residues on histone H3 (HH3) and HH4 acetylated in this process.

HG treatment of THP-1 monocytes increased the transcriptional activity of NF-kappaB p65, which was augmented by CBP/p300 and p/CAF.
|

14976218
|
ChIP assays showed that HG increased the recruitment of NF-kappaB p65, CPB, and p/CAF to the TNF-alpha and COX-2 promoters.
|
12 |
14976218
|
Interestingly, ChIP assays also demonstrated concomitant acetylation of HH3 at Lys(9) and Lys(14), and HH4 at Lys(5), Lys(8), and Lys(12) at the TNF-alpha and COX-2 promoters.

Overexpression of histone deacetylase (HDAC) isoforms inhibited p65-mediated TNF-alpha transcription.

Finally, we demonstrated increased HH3 acetylation at TNF-alpha and COX-2 promoters in human blood monocytes from type 1 and type 2 diabetic subjects relative to nondiabetic.

We hypothesized that halofenate might be an insulin sensitizer, and we present data to suggest that halofenate is a selective peroxisome proliferator-activated receptor (PPAR)-gamma modulator (SPPARgammaM).

The data suggest that the partial agonism of HA may be explained in part by effective displacement of corepressors (N-CoR and SMRT) coupled with inefficient recruitment of coactivators (p300, CBP, and TRAP 220).

CITED2 is expressed in human adrenocortical cells and regulated by basic fibroblast growth factor.

|
Therefore, we analyzed CITED2, a CBP/p300 interacting transactivator with transforming activity, in the human adrenal gland.
|

|
As ACTH and basic fibroblast growth factor (bFGF) are connected to the physiology and growth of adrenocortical cells we studied the regulation of CITED2 by these factors in the NCI-H295R adrenocortical carcinoma cell line.
|
27 |

|
In NCI-H295R cells, stimulation by bFGF led to a dose-dependent increase in CITED2 promotor activity, mRNA and protein expression while ACTH had no significant effect.

Interestingly, a CBP/p300-interacting transactivator with ED-rich tail 2 (CITED2), which is necessary for adrenal development, has been linked to aldosterone synthesis.

Histone acetyltransferases (HATs) GCN5 and PCAF (GCN5/PCAF) and CBP and p300 (CBP/p300) are transcription co-activators.

In contrast, CBP/p300 and their HAT activities are essential for ligand-induced Pol II recruitment on, and activation of, NR target genes.
