The platelet tests uniformly revealed rebound activation by all platelet measures (at least twofold increase) while being especially high for ADP-, and collagen-induced aggregation, platelet/endothelial cell adhesion molecule-1 (PECAM-1), glycoprotein (GP)Ib, GPIIb/IIIa activity, P-selectin, protease activated receptor (PAR)-1 thrombin receptor (activated and intact epitopes), and thrombospondin expression. | |||||||||||||||
| |||||||||||||||
|
We next want to test whether E2F1 could up-regulate expression of the endogenous TSP1 gene. | |||||||||||||||
| |||||||||||||||
|
These observations suggested that the DNA binding activity of E2F1 is required for inducing TSP1 expression. | |||||||||||||||
| |||||||||||||||
|
These observations suggested that E2F-1 could regulate TSP1 expression by directly binding to its promoter. | |||||||||||||||
| |||||||||||||||
|
Using promoter assays, Northern blot and ChIP (chromatin immunoprecipitation) assays, we identified that E2F-1 could directly transactivate TSP1 expression by binding to its promoter, further expending TSP1's regulatory factors.
| |||||||||||||||
| |||||||||||||||
|
Taking advantage of cell culture system and zebrafish model, we have identified that ELL could serve as a transcriptional factor to directly up-regulate TSP1 expression [31]. | |||||||||||||||
| |||||||||||||||
|
Of cause, how E2F-1 acting its role in anti-angiogenesis through the regulation of TSP1 expression is definitely worth to be further investigated.
| |||||||||||||||
| |||||||||||||||
|
In addition, we verified that the DNA binding domain and DNA binding ability of E2F-1 were required for transactivating TSP1 expression. | |||||||||||||||
| |||||||||||||||
|
Some authors, have been demonstrated that expresion of TSP-1 is higher in endometriotic lesions and is associated to the extent of their vascularization. | |||||||||||||||
| |||||||||||||||
|
All results of thrombospondin-1 expression were analysed by the Student's t-test. | |||||||||||||||
| |||||||||||||||
|
To further verify E2F-1 binding sites in the promoter of TSP1, on the basis of TSP1-promoter (? | |||||||||||||||
| |||||||||||||||
|
Targeted overexpression of TSP1 in mice suppressed wound healing and tumorigenesis, while lack of functional TSP1 resulted in increased vascularization of selected tissues and significantly decreased the number of excitatory synapses [13], [21], [30]. | |||||||||||||||
| |||||||||||||||
|
In this study, through domain mapping for TSP1 promoter, we identified that the E2F-1 binding consensus sequence located in ? | |||||||||||||||
| |||||||||||||||
|
At the same time, different function domains of E2F1 were cloned into Flag-tagged vector and co-transfected into 293 cells with TSP1 promoter luciferase reporter TSP1(? | |||||||||||||||
| |||||||||||||||
|
Then, we did dose response experiments for E2F-1 overexpression on TSP1 promoter activity. | |||||||||||||||
| |||||||||||||||
|
Flag empty vector or different dose of Flag-tagged E2F-1 expression vector, TSP1(? | |||||||||||||||
| |||||||||||||||
|
At the same time, different function domains of E2F1 were cloned into Flag-tagged vector and co-transfected into 293 cells with TSP1 promoter luciferase reporter TSP1(? | |||||||||||||||
| |||||||||||||||
|
Thus, TSP1, CASP8, HIC1, DcR1, DcR2 and DR4 and RASSF1 were methylated frequently in both tumour types (Astuti et al. 2001c, Margetts et al. 2005). | |||||||||||||||
| |||||||||||||||
|
Both PAR2 and PAR1 activation resulted in up-regulated expression of several genes (CD44, FOSL1, TNFRSF12A, RAB3A, COPEB, CORO1C, THBS1, SDC4) known to be important in cancer. | |||||||||||||||
| |||||||||||||||
|
Previously, it was known to be only activated by PAR1, but now we suggest that PAR2 can also trigger expression of thrombospondin-1.
