Stem cell factor (SCF) is a highly expressed cytokine in the central nervous system. In the present study, we demonstrate a neuroprotective role for SCF and its tyrosine kinase receptor, c-kit, against camptothecin-induced apoptosis and glutamate excitotoxicity in rat cortical neurons. This protection was blocked by pharmacological or molecular inhibition(More)
OBJECT Intracerebral hemorrhage (ICH) is associated with significant morbidity and mortality. Acute hematoma enlargement is an important predictor of neurological injury and poor clinical prognosis; but neurosurgical clot evacuation may not be feasible in all patients and treatment options remain largely supportive. Thus, novel therapeutic approaches to(More)
Basic fibroblast growth factor (bFGF) and transforming growth factor-beta1 (TGF-beta1) play an important role in proliferation, differentiation, and survival of malignant gliomas and in normal glial cell biology. Because of these critical roles, potential interactions between these key growth factors were investigated. We previously demonstrated that bFGF(More)
17beta-Estradiol (E2) and selective estrogen receptor modulators (SERMs), such as tamoxifen, mediate numerous effects in the brain, including neurosecretion, neuroprotection, and the induction of synaptic plasticity. Astrocytes, the most abundant cell type in the brain, influence many of these same functions and thus may represent a mediator of estrogen(More)
This study used the mRNA differential display technique to identify differentially expressed genes during the process of adipogenesis in the preadipocyte cell line, 3T3-L1. 3T3-L1 cells were treated with dexamethasone, isobutyl-1-methylxanthine, and insulin to induce differentiation into mature adipocytes. Cells were collected at three time-points during(More)
BACKGROUND Numerous factors may give rise to the loss of femoral bone stock that can be encountered in revision hip arthroplasty. Proximal femoral replacement is an option for the treatment of severe proximal femoral bone loss. In this study, we sought to determine the outcome of reconstructive surgery with the use of a modular proximal femoral replacement(More)
