phosphorylation of DDR1 in mammary epithelial cells and on adhesion of such
cells to collagen,9 we first tested the impact of pertussis and cholera toxins
on the collagen-induced phosphorylation of DDR1 in normal HB2 cells. We found
that the phosphorylation was almost abolished by pertussis toxin (Fig. 2a,b), but
was not affected by cholera toxin (Fig. 2c).""" ;
