in this review the role of cerebrospinal fluid (csf) in mammalian cerebral cortex development has been highlighted. many studies have focused on the potential role of the csf in the developmental process. in particular, the cerebral cortex develops from the germinal epithelium adjacent to the csf. csf contains proteins, growth factors and other neurotrophic factors which are important for neura...

Tyrosine hydroxylase is synthesized de novo in rat superior cervical ganglia in organ culture. The differential rate of synthesis is not increased significantly by the addition of nerve growth factor to the culture. Prior administration of nerve growth factor in vivo, however, leads to an augmented synthesis of tyrosine hydroxylase in ganglia subsequently cultured in vitro. The differential rat...

Studies have shown that sensory nerve damage can activate the p38 mitogen-activated protein kinase (MAPK) pathway, but whether the same type of nerve injury after exercise activates the p38MAPK pathway remains unclear. Several studies have demonstrated that nerve growth factor may play a role in the repair process after peripheral nerve injury, but there has been little research focusing on the...

This study investigated the regulation of Wilms' tumor gene (WT1) in the ovary by nerve growth factor and FSH to better understand signals that initiate early follicular growth. Nerve growth factor showed a direct stimulatory effect on endogenous expression of WT1, whereas FSH attenuated basal and nerve growth factor-stimulated WT1 protein expression, which most likely depended on FSH responsiv...

A previous study has demonstrated that locally administered growth factors such as epidermal growth factor, basic fibroblast growth factor and hepatocyte growth factor can accelerate healing of experimental gastric ulcers in rats. That study indicates that locally administered growth factors can exert potent biological effects resulting in enhanced gastric ulcers healing. However, the fate of i...

the spontaneous regression of neuroblastoma to ganlioneuroma is a rare occurrence. reviewing the literature, we found no more than 12casesreported.'•2.9.,o.'4.1s we report a case of metastatic neuroblastoma of multifocal skeletal and soft tissue areas with gross deformities which regressed to ganglioneuroma, with good prognosis.

background: the potential of plants as a safe and eukaryotic systems, are considered for producing recombinant therapeutic human protein today; but the expression level of heterologous proteins is limited by the post-transcriptional gene silencing (ptgs) response in this new technology. the use of viral suppressors of gene silencing can prevent ptgs and improve transient expression level of for...

Nerve growth factor induces cell death in organotypic cultures of otic vesicle explants. This cell death has a restricted pattern that reproduces the in vivo pattern of apoptosis occurring during inner ear development. In this study, we show that binding of nerve growth factor to its low affinity p75 neurotrophin receptor is essential to achieve the apoptotic response. Blockage of binding to p7...
