Osteopontin (OPN) is a neuroprotective molecule that is upregulated following rodent neonatal hypoxic-ischemic (nHI) brain injury. Because Rac1 is a regulator of blood-brain barrier (BBB) stability, we hypothesized a role for this in OPN signaling. nHI was induced by unilateral ligation of the right carotid artery followed by hypoxia (8 % oxygen for 2 h) in(More)
Germinal matrix hemorrhage (GMH) is the most common and devastating neurological problem of premature infants. Current treatment is largely ineffective and GMH has been nonpreventable. Osteopontin (OPN) is an endogenous protein that has been shown to be neuroprotective, however, it has not been tested in GMH. P7 neonatal rats were subjected to stereotactic(More)
BACKGROUND Germinal matrix hemorrhage is a leading cause of mortality and morbidity from prematurity. This brain region is vulnerable to bleeding and re-bleeding within the first 72 hours of preterm life. Cerebroventricular expansion of blood products contributes to the mechanisms of brain injury. Consequences include lifelong hydrocephalus, cerebral palsy,(More)
