iCRT3 has been used:
- for β- catenin inhibition in dual luciferase assay
- to inhibit β-catenin /TCF interactions and their transcriptional activity
- as wingless/tailess (wnt) antagonist, to determine Wnt/β-catenin signaling is essential for PROX1-mediated regulation of forkhead box protein C2 (FOXC2)(3)catenin inhibition in dual luciferase assay
- to inhibit β- catenin /TCF interactions and their transcriptional activity
- as wingless/tailess (wnt) antagonist, to determine Wnt/β-catenin signaling is essential for PROX1-mediated regulation of forkhead box protein C2 (FOXC2)
| [Uses]
iCRT3, is an inhibitor of both Wnt and β-catenin-responsive transcription (CRT). | [General Description]
iCRT3 is a small cell-permeable oxazole compound. It blocks cytokine secretion in lipopolysaccharide (LPS)-stimulated macrophages. | [Biochem/physiol Actions]
The key mediator of Wnt signaling is the transcriptional co-activator b-catenin. In the cytoplasm, b-catenin is tightly bound to a complex that includes Axin and GSK-3b. Stimulation causes b-catenin stabilization, translocation to the nucleus and association with TCF4 to initiate transcription of responsive genes, referred to as Catenin Responsive Transcription (CRT). Virtually all Wnt-associated cancers are the result of misregulated CRT. Three inhibitors of CRT (iCRT) were identified in a screen that employed RNAi based knockdown of Axin, which stimulates CRT without affecting upstream mechanisms such as GSK activity, transduction by disheveled / frizzled, etc. These compounds are potent inhibitors of CRT reporter genes, as well as endogenous gene targets. The compounds also disrupt b-catenin-TCF4 interaction in a dose dependent manner, and cause G0/G1 arrest in colon tumor lines. | [in vivo]
The tumor growth rates are markedly retarded by iCRT3 treatment. Consistently, the tumor-suppressive role of iCRT3 is accompanied with a reduction in Ki67 index, a proliferation marker[1]. The IL-6 levels in the 10 mg/kg iCRT3 treatment group are 82.9% lower than those in the vehicle group. IL-1β levels are undetectable in the sham but reach 371 pg/mL in septic mice and are down by 30.2% and 53.2%, respectively, with 5 and 10 mg/kg iCRT3. With iCRT3 treatment at doses of 5 and 10 mg/kg, AST levels in these septic mice are 15.4% and 44.2% lower, respectively, than those in the vehicle-treated mice. After treatment with 10 mg/kg iCRT3, lung morphology is improved with much reduced microscopic deterioration, compare to the vehicle group. The number of apoptotic cells in the lung tissues of the iCRT3-treated mice is significantly reduced by 92.7% in comparison with the vehicle group[3]. |
