~50% of colorectal cancers with microsatellite instability show frameshift mutations in TCF7L2 that result in the loss of the CTBP-binding region (Duval et al, 1999; Cuillliere-Dartigues et al, 2006). These cancer cells show decreased colocalization of CTBP and TCF7L2 and have increased expression of a TCF-dependent reporter gene (Cuilliere-Dartigues et al, 2006).
