To participate as co-receptor in growth factor signaling, heparan sulfate must have specific structural features. Recent studies show that when the levels of 6-O-sulfation of heparan sulfate are diminished by the activity of extracellular heparan sulfate 6-O-endosulfatases (Sulfs), fibroblast growth factor 2-, heparin binding epidermal growth factor-, and(More)
OBJECTIVES/HYPOTHESIS Propranolol has recently been introduced as a novel pharmacologic treatment for infantile hemangiomas. Systematic examination of this treatment in a tertiary care setting has not been described. This study explores the impact of propranolol on both proliferative and involuting hemangiomas at a tertiary vascular anomalies center. (More)
The heparan sulfate proteoglycan syndecan-1 is expressed by myeloma cells and shed into the myeloma microenvironment. High levels of shed syndecan-1 in myeloma patient sera correlate with poor prognosis and studies in animal models indicate that shed syndecan-1 is a potent stimulator of myeloma tumor growth and metastasis. Overexpression of extracellular(More)
IMPORTANCE Endoglin (CD105) and endothelial nitric oxide synthase (eNOS) assist in regulating vascular development. Variation in expression of these factors is linked to errors in vascular growth and remodeling in invasive lesions. OBJECTIVE To clarify the role of endoglin and eNOS in the growth of extracranial head and neck arteriovenous malformations(More)
BACKGROUND Arteriovenous malformations (AVMs) are a type of high-flow vascular malformations that most commonly occurs in the head and neck. They are present at birth but are usually clinically asymptomatic until later in life. The pathogenesis of AVMs remains unclear and therapeutic approaches to AVMs are unsatisfied. In order to provide a tool for(More)
