SRC-1 and GRIP1 coactivate transcription with hepatocyte nuclear factor 4.
|
2 |
9812974
|
In this study, we show that SRC-1 and GRIP1, which act as coactivators for various nuclear receptors, associate with HNF4 in vivo and enhance its transactivation potential.
|
3 |
9812974
|
The AF-2 domain of HNF4 is required for this interaction and for the potentiation of transcriptional activity by these coactivators. p300 can also serve as a coactivator with HNF4, and it synergizes with SRC-1 to further augment the activity of HNF4.
|
4 |
9812974
|
HNF4 is also a key regulator of the expression of hepatocyte nuclear factor-1 (HNF1).
|
5 |
9812974
|
The overexpression of SRC-1 or GRIP1 enhances expression from a HNF1 gene promoter-reporter in HepG2 hepatoma cells, and this requires an intact HNF4-binding site in the HNF1 gene promoter.
|
6 |
9812974
|
Type 1 maturity onset diabetes of young (MODY), which is characterized by abnormal glucose-mediated insulin secretion, is caused by mutations of the HNF4 gene.
|
7 |
9812974
|
A mutation of the HNF4-binding site in the HNF1 gene promoter has also been associated with MODY.
|
8 |
9812974
|
Thus, HNF4 is involved in the regulation of glucose homeostasis at several levels and along with the SRC-1, GRIP1, and p300 may play an important role in the pathophysiology of non-insulin-dependent diabetes mellitus.

Candidate factors have been identified by the observation that changes in glucocorticoid induction parameters in CV-1 cells could be reproduced by varying the cellular levels of coactivators [transcriptional intermediary factor 2 (TIF2), steroid receptor coactivator 1 (SRC-1), and amplified in breast cancer 1 (AIB1)], comodulator [CREB-binding protein (CBP)], or corepressor [silencing mediator for retinoid and thyroid-hormone receptors (SMRT)] without concomitant increases in GR.
|
64 |
10598585

Significantly, the effects of TIF2 and SMRT were mutually antagonistic.

Furthermore, the corepressors SMRT (silencing mediator for retinoid and thyroid receptors) and NCoR (nuclear receptor corepressor) each suppresses gene induction but NCoR acts opposite to SMRT and, like the coactivator TIF2, reduces the EC(50) and increases the partial agonist activity of antiprogestins.

Dax-1 and steroid receptor RNA activator (SRA) function as transcriptional coactivators for steroidogenic factor 1 in steroidogenesis.
|
86 |
19188450
|
The atypical orphan nuclear receptor Dax-1 binds to SF-1 and represses SF-1 target genes.
|
87 |
19188450
|
Paradoxically, however, loss-of-function mutations of Dax-1 also cause adrenal hypoplasia, suggesting that Dax-1 may function as an SF-1 coactivator under some circumstances.
|
88 |
19188450
|
Indeed, we found that Dax-1 can function as a dosage-dependent SF-1 coactivator.
|
89 |
19188450
|
Both SF-1 and Dax-1 bind to steroid receptor RNA activator (SRA), a coactivator that functions as an RNA.
|
90 |
19188450
|
The coactivator TIF2 also associates with Dax-1 and synergistically coactivates SF-1 target gene transcription.
|
91 |
19188450
|
Coactivation by Dax-1 is abolished by SRA knockdown.
|
92 |
19188450
|
The expression of the steroidogenic gene products steroidogenic acute regulatory protein (StAR) and melanocortin 2 receptor is reduced in adrenal Y1 cells following the knockdown of endogenous SRA.
|
93 |
19188450
|
Similarly, the knockdown of endogenous Dax-1 downregulates the expression of the steroidogenic gene products CYP11A1 and StAR in both H295R adrenal and MA-10 Leydig cells.
|
94 |
19188450
|
These findings reveal novel functions of SRA and Dax-1 in steroidogenesis and adrenal biology.

Transcriptional activation by steroid hormone receptors is accompanied by changes in histone and non-histone protein post-translational modification (PTM) that result from the enzymatic activity of coactivator and corepressor proteins such as GRIP1 and CARM1.
|
96 |

We postulate that iAs effects on CARM1 and GRIP1 may underlie some of its therapeutic effects and as well be associated with its toxic effects.

106 |
21035760

Moreover, our results demonstrate that SRC-1 and TIF2 can modulate the expression of the uncoupling protein 3 (UCP3) in an antagonistic manner and that enhanced SRC-1 levels in TIF2-deficient myofibers are critically involved in the metabolic changes of TIF2((i)skm)⁻(/)⁻ mice.

The transcriptional coactivators p/CIP and SRC-1 control insulin resistance through IRS1 in obesity models.
|
114 |
22859932
|
Three p160 family members, p/CIP, SRC1, and TIF2, have been identified as transcriptional coactivators for nuclear hormone receptors and other transcription factors in vitro.
|
115 |
22859932
|
In a previous study, we reported initial characterization of the obesity-resistant phenotypes of p/CIP and SRC-1 double knockout (DKO) mice, which exhibit increased energy expenditure, and suggested that nuclear hormone receptor target genes were involved in these phenotypes.
|
116 |
22859932
|
In this study, we demonstrate that p/CIP and SRC1 control insulin signaling in a cell-autonomous manner both in vitro and in vivo.
|
117 |
22859932
|
Genetic deletion of p/CIP and SRC-1 increases glucose uptake and enhances insulin sensitivity in both regular chow- and high fat diet-fed DKO mice despite increased food intake.
|
118 |
22859932
|
Interestingly, we discover that loss of p/CIP and SRC-1 results in resistance to age-related obesity and glucose intolerance.
|
119 |
22859932
|
We show that expression levels of a key insulin signaling component, insulin receptor substrate 1 (IRS1), are significantly increased in two cell lines representing fat and muscle lineages with p/CIP and SRC-1 deletions and in white adipose tissue and skeletal muscle of DKO mice; this may account for increased glucose metabolism and insulin sensitivity.
|
120 |
22859932
|
This is the first evidence that the p160 coactivators control insulin signaling and glucose metabolism through IRS1.
|
121 |
22859932
|
Therefore, our studies indicate that p/CIP and SRC-1 are potential therapeutic targets not only for obesity but also for diabetes.

Insulin-like growth factor 1 mRNA expression in the uterus of streptozotocin-treated diabetic mice.
|
124 |
23719562
|
We aimed to clarify the changes in the estrous cycle and in insulin-like growth factor 1 (IGF1) expression in the uteri of streptozotocin (STZ)-treated diabetic mice, because IGF1 is one of the main growth factors involved in estrogen-induced uterine growth.
|
125 |
23719562
|
Estrogen is known to stimulate Igf1 mRNA expression in the uterus, but estrogen action was abolished in the uteri of STZ-treated diabetic mice. mRNA expressions of estrogen receptor α (ERα) and steroid hormone receptor coactivators (SRC-1/Ncoa1, SRC-2/Ncoa2, SRC-3/Ncoa3 and CBP/p300/Crebbp) were reduced in the uteri of ovariectomized STZ-treated diabetic mice.
|
126 |
23719562
|
Igf1 expression in ovariectomized diabetic female mice was decreased, and decreased responsiveness to estrogen in the uteri of diabetic mice is probably associated with a reduction in ERα and steroid receptor coactivator mRNA expression.
