in the lung (Moens et al., 1993; Okubo et al., 2005; Sawai et al., 1993; Stanton
et al., 1992). Furthermore, N-myc has been recently implicated in the regulation
of distal airway progenitor development (Okubo et al., 2005). c-myc, a highly
related myc gene, is a well-established down-stream target of Wnt/β-catenin
signaling in several tissues including intestinal epithelium (Anna et al., 2003;
Cong et al., 2003; Pinto et al., 2003).""" ;
