Biological Activity for iCRT 14

iCRT 14 is a potent inhibitor of β-catenin-responsive transcription (CRT) (IC50 = 40.3 nM in assays of Wnt pathway activity). Thought to directly influence the interaction between β-catenin and TCF4. Induces marked G0/G1 cell cycle arrest in HCT-116 and HT29 cell lines. Also acts as transfection enhancer; enhances transgene expression in PC-3 cells by 16 to 35-fold using nonviral systems.

Wnt Signaling Pathway

Wnt Signaling Pathway

The Wnt pathway is involved in cellular differentiation and proliferation in adult tissues and also during embryogenesis. Disturbances within the pathway may lead to the formation of tumors and promote metastasis.
