Report of the Jumpstarting Brain Tumor Drug Development Coalition and FDA clinical trials clinical outcome assessment endpoints workshop (October 15, 2014, Bethesda MD).

On October 15, 2014, a workshop was held on the use of clinical outcome assessments in clinical trials for high-grade glioma of the brain. This workshop was sponsored by the Jumpstarting Brain Tumor Drug Development Coalition, consisting of the National Brain Tumor Society, the Society for Neuro-Oncology, the Musella Foundation for Brain Tumor Research and Information, and Accelerate Brain Cancer Cure. It was planned and carried out with participation from the US Food and Drug Administration.

Effects of pre-natal alcohol exposure on hippocampal synaptic plasticity: Sex, age and methodological considerations.

The consumption of alcohol during gestation is detrimental to the developing central nervous system (CNS). The severity of structural and functional brain alterations associated with alcohol intake depends on many factors including the timing and duration of alcohol consumption. The hippocampal formation, a brain region implicated in learning and memory, is highly susceptible to the effects of developmental alcohol exposure.

Prenatal ethanol (EtOH) exposure alters the sensitivity of the adult dentate gyrus to acute EtOH exposure.

Background: Prenatal ethanol (EtOH) exposure results in a spectrum of structural, cognitive, and behavioral abnormalities, collectively termed "fetal alcohol spectrum disorders" (FASDs). The hippocampal formation, an area of the brain strongly linked with learning and memory, is particularly vulnerable to the teratogenic effects of EtOH. Prenatal EtOH exposure can lead to long-lasting impairments in the ability to process spatial information, as well as produce long-lasting deficits in the ability of animals to exhibit long-term potentiation (LTP), a biological model of learning and memory processing.

Enhanced deficits in long-term potentiation in the adult dentate gyrus with 2nd trimester ethanol consumption.

Ethanol exposure during pregnancy can cause structural and functional changes in the brain that can impair cognitive capacity. The hippocampal formation, an area of the brain strongly linked with learning and memory, is particularly vulnerable to the teratogenic effects of ethanol. In the present experiments we sought to determine if the functional effects of developmental ethanol exposure could be linked to ethanol exposure during any single trimester-equivalent.

The effects of exercise on adolescent hippocampal neurogenesis in a rat model of binge alcohol exposure during the brain growth spurt.

Exposure to alcohol during the brain growth spurt results in impaired cognition and learning in adulthood. This impairment is accompanied by permanent structural changes in the hippocampal formation. Exercise improves performance on hippocampal-dependent learning and memory tasks and increases adult neurogenesis in the rat hippocampal dentate gyrus.

Binge-like postnatal alcohol exposure triggers cortical gliogenesis in adolescent rats.

The long-term effects of binge-like postnatal alcohol exposure on cell proliferation and differentiation in the adolescent rat neocortex were examined. Unlike the hippocampal dentate gyrus, where proliferation of progenitors results primarily in addition of granule cells in adulthood, the vast majority of newly generated cells in the intact mature rodent neocortex appear to be glial cells. The current study examined cytogenesis in the motor cortex of adolescent and adult rats that were exposed to 5.

Persistent impairment of hippocampal neurogenesis in young adult rats following early postnatal alcohol exposure.

Background: Prenatal alcohol exposure can cause damage to the developing fetus with outcomes including growth deficiency, facial dysmorphology, brain damage, and cognitive and behavioral deficits. Smaller brains in children with FASD have been linked both with reduced cell proliferation in the developing CNS and with apoptotic cell loss of postmitotic neurons. Prenatal alcohol exposure in rodents during the period of brain development comparable to that of the first and second trimesters of human pregnancy persistently alters adult neurogenesis.
