We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

Cell Death and Behavior After Neonatal Hypoxia-Ischemia
The goal of the proposed research is to determine the long-term protective properties of caspase-3 blockade in mice subjected to hypoxia-ischemia (H-I) as neonates. Neonatal H-I results in necrotic and apoptotic cell death; brain-derived neurotrophic factor (BDNF)protects both neural tissue and behavioral function following H-I in rats. The first objective of the proposed research is to determine the effectiveness of BDNF pre-treatment in providing long-term protection of brain tissue and behavior following neonatal H-I in mice. The second objective is to determine relationships among regional and cellular brain tissue measures, spatial memory function, and sensory-motor abilities in two strains of mice with mutations in the caspase-3 activation pathway (Bax and caspase-3 knockout). The third objective is to examine brain injury, spatial memory, and sensory-motor performance in Bax and caspase-3 knockout strains following neonatal H-I. The Levine H-I method (unilateral carotid ligation followed by reduced oxygen) will be performed on postnatal day 7 (PN7) mice. Spatial memory will be tested in a Morris water maze task and sensory-motor abilities will be tested at PN 30-45 and at PN85-100. After behavioral testing, quantitative regional volumes of hippocampus and cortex and density of CA1neurons in the hippocampus will be assessed stereologically. Detailed analyses of the effects of caspase-3 inhibition via pharmacological or genetic manipulation will be useful in the further development of neural and behavioral protective agents and strategies following neonatal H-I.
