MUC1 and Patent ductus arteriosus: In PDA, MUC1 interacts with both E- and P-selectins (Mcdermott et al., 2001) to facilitate extravasation and transmits signals into the cell from the surrounding microenvironment to induce increased invasion through stabilization and phosphorylation of FRA-1 and c-JUN (Hanson et al., 2016; Besmer et al., 2011).
