Role in Cardiac Development and Vasculature
HB-EGF binding and activation of EGF receptors plays a critical role during cardiac valve tissue development and the maintenance of normal heart function in adults. During valve tissue development the interaction of HB-EGF with EGF receptors and heparan sulfate proteogylcans is essential for the prevention of malformation of valves due to enlargement. In the vascular system areas of disturbed flow show upregulation of HB-EGF with promotion of vascular lesions, atherogenesis, and hyperplasia of intimal tissue in vessels. The flow disturbance remodeling of the vascular tissues due to HB-EGF expression contributes to aortic valve disease, peripheral vascular disease, and conduit stenosis.

Famous quotes containing the words role in, role and/or development:
“Friends serve central functions for children that parents do not, and they play a critical role in shaping children’s social skills and their sense of identity. . . . The difference between a child with close friendships and a child who wants to make friends but is unable to can be the difference between a child who is happy and a child who is distressed in one large area of life.”
—Zick Rubin (20th century)
“This [new] period of parenting is an intense one. Never will we know such responsibility, such productive and hard work, such potential for isolation in the caretaking role and such intimacy and close involvement in the growth and development of another human being.”
—Joan Sheingold Ditzion and Dennie Palmer (20th century)
“The highest form of development is to govern one’s self.”
—Zerelda G. Wallace (1817–1901)
