FMOD and breast cancer: Our results confirm and extend the involvement of Wnt/β-catenin pathway in various tumors (Jansson et al., 2005; Iwai et al., 2010; Anastas and Moon, 2013; Dey et al., 2013) by demonstrating the crucial role of the Wnt/β-catenin pathway in promoting breast cancer metastasis via regulating FMOD transcription.
