Description |
ICG-001 is an inhibitor of β-catenin/TCF mediated transcription. It works by specifically binding to cyclic AMP response element-binding protein with an IC50 of 3 μM.

Target |
IC50: 3 μM (CBP)

In Vitro |
ICG-001 (5μM) inhibits leptin-induced EMT, invasion and tumorsphere formation in MCF7 cells[1]. ICG-001 can phenotypically rescue normal nerve growth factor (NGF)-induced neuronal differentiation and neurite outgrowth in the presenilin-1 mutant cells, emphasizing the importance of the TCF/β-catenin signaling pathway on neurite outgrowth and neuronal differentiation[2]. ICG-001 (25μM) treatment reduces the steady-state levels of Survivin and Cyclin D1 RNA and protein in SW480 cells, both of which can be up-regulated by β-catenin. ICG-001 selectively induces apoptosis in transformed cells but not in normal colon cells, and reduces in vitro growth of colon carcinoma cells[3].

In Vivo |
ICG-001 (5 mg/kg per day) significantly inhibits beta-catenin signaling and attenuates bleomycin-induced lung fibrosis in mice, while concurrently preserving the epithelium[2]. Administration of a water-soluble analog of ICG-001 for 9 weeks reduces the formation of colon and small intestinal polyps by 42% as effectively as the nonsteroidal antiinflammatory agent Sulindac, which has consistently demonstrated efficacy in this model. ICG-001 (150 mg/kg, i.v.) demonstrates a dramatic reduction in tumor volume over the 19-day course of treatment, with no mortality or weight loss in the SW620 nude mouse xenograft model of tumor regression[3].

Cell Assay |
To evaluate effects of ICG-001 on α-SMA and collagen type 1 expression, RLE-6TN cells are treated with TGF-β1 (0.25 ng/mL) in the presence or absence of ICG-001 (5.0 μM). After 24 h, cells are harvested and mRNA isolated for analysis by qPCR. RNA is reverse-transcribed using SuperScript reverse transcriptase. Quantitative PCR is performed with SYBR-Green PCR using Real-Time PCR System HT7900. The amplification protocol is set as follows: 95°C denaturation for 10 min followed by 40 cycles of 15-s denaturation at 95°C, 1 min of annealing/extension, and data collection at 60°C.

Animal Admin |
Seven-week-old male C57BL/6J-ApcMin/+and WT C57BL/6J mice are treated orally for 9 weeks with ICG-001a (300 mg/kg per day) or vehicle (1% carboxymethylcellulose), once daily, six times per week. Sulindac is administered in drinking water (160 ppm, dissolved in 8 mM Na2PO4 buffer, pH 7.6). At 16 weeks, the polyp number is counted manually by using a dissecting microscope.
