We identified three sites that were essential for basal COX-2 promoter activity: 1) CCAAT/enhancer-binding protein (C/EBP), 2) aryl hydrocarbon receptor (AhR), and 3) cAMP response element-binding protein (CREB).
|

|
Double mutation of the AhR and CREB-binding sites showed synergy in repressing COX-2 promoter activity as did mutation of all three sites.

|
We demonstrated that the transcription factors from RINm5F nuclear extracts specifically bound to oligonucleotides containing C/EBP, AhR, or CREB consensus sites.

|
Forskolin, an activator of adenyl cyclase, increased COX-2 promoter activity via the CREB site.
|

|
COX-2 promoter activity was also increased by 2,3,7,8-tetrachlorodibenzo-p-dioxin, an AhR activator, through the AhR site.

Here we demonstrate that whereas some members of the family of bone morphogenetic proteins (BMPs) support white adipocyte differentiation, BMP7 singularly promotes differentiation of brown preadipocytes even in the absence of the normally required hormonal induction cocktail.
|

|
BMP7 activates a full program of brown adipogenesis including induction of early regulators of brown fat fate PRDM16 (PR-domain-containing 16; ref. 4) and PGC-1alpha (peroxisome proliferator-activated receptor-gamma (PPARgamma) coactivator-1alpha; ref. 5), increased expression of the brown-fat-defining marker uncoupling protein 1 (UCP1) and adipogenic transcription factors PPARgamma and CCAAT/enhancer-binding proteins (C/EBPs), and induction of mitochondrial biogenesis via p38 mitogen-activated protein (MAP) kinase-(also known as Mapk14) and PGC-1-dependent pathways.

Moreover, BMP7 triggers commitment of mesenchymal progenitor cells to a brown adipocyte lineage, and implantation of these cells into nude mice results in development of adipose tissue containing mostly brown adipocytes.
|

|
Bmp7 knockout embryos show a marked paucity of brown fat and an almost complete absence of UCP1.

|
These data reveal an important role of BMP7 in promoting brown adipocyte differentiation and thermogenesis in vivo and in vitro, and provide a potential new therapeutic approach for the treatment of obesity.

NCB5OR is a novel flavoheme reductase with a cytochrome b5-like domain at the N-terminus and a cytochrome b5 reductase-like domain at the C terminus.

|
Ncb5or knock-out mice develop insulin deficient diabetes and loss of white adipose tissue.

The ER stress response was assessed by induction of BiP, ATF3, ATF6, XBP-1, and C/EBP homologous protein (CHOP).
|
19 |

|
In order to assess the role of ER stress in vivo, we prepared mice that lack both NCB5OR and CHOP, a proapoptotic transcription factor important in the ER stress response.

Ablation of C/EBP homologous protein does not protect T17M RHO mice from retinal degeneration.

The purpose of this study is to investigate the role of CHOP protein in T17M RHO retina.
|
22 |
23646198
|
Wild-type, CHOP-/-, T17M RHO and T17M RHO CHOP-/-mice were used in the study.
|
23 |

|
Dark-adapted ERG analysis demonstrated that by 1 month, the T17M RHO CHOP-/- mice had a 70% reduction of the a-wave amplitude compared to the T17M RHO mice.
|

|
The loss of function in T17M RHO CHOP-/- photoreceptors was associated with a 22-24% decline in the thickness of the outer nuclear layer.
|
25 |

|
These mice had significant reduction in the expression of transcription factors, Crx and Nrl, and also in mouse Rho, and human RHO.
|
26 |

|
In addition, the histone deacetylase 1 (Hdac1) protein was 2-fold elevated in the T17M RHO CHOP-/- retina.
|
27 |

|
The ablation of CHOP led to a reduction in the expression of photoreceptor-specific transcriptional factors, and both endogenous and exogenous RHO mRNA.
