General description
Neuron-specific enolase (NSE) is a neuronal form of the glycolytic enzyme enolase, which was first found in extracts of brain tissue.
Application
Neuron-specific enolase from human brain has been used in a study to assess human amniotic mesenchymal stem cells in the treatment of focal cerebral ischemia. It has also been used in a study to investigate sinonasal teratocarcinosarcoma with rhabdoid features.
Biochem/physiol Actions
Neuron-specific enolase (NSE) is expressed in all neuronal cell types, and its expression marks the acquisition of synaptic function. Following acute neuronal injury, NSE levels are increased in neuronal cell bodies. Increased levels of NSE in serum and cerebrospinal fluid have been used as markers for injury and neuronal cell death. Tumors derived from many cell types, including most neuronal and neuroendocrine tumors, express NSE.
Neuron-specific enolase promotes survival of neurons and can provide neuroprotective effects by binding to neurons in a calcium-dependent manner.

Sinonasal teratocarcinosarcoma (SNTCS) is a very rare tumor developed in the nasal cavity and paranasal sinuses. The rhabdoid phenotype represents an aggressive biological behavior, but the rhabdoid feature has hitherto not been reported in cases of SNTCS. A 46-year-old man

We previously reported that the gamma gamma-isozyme of enolase, NSE), one of the glycolytic enzymes, promoted the survival of embryonic rat neocortical neurons in culture, but alpha alpha-isozyme (non-neuronal enolase) had no effect. In the present study, the neurotrophic effects
