Introduction
Neuron-specific enolase, also known as NSE, is a glycolytic isoenzyme found in central and peripheral neurons and neuroendocrine cells. Enolase-2 is released into the cerebrospinal fluid (CSF) following neural tissue injury. Neoplasms originating from neural or neuroendocrine tissue release Enolase-2 into the bloodstream. Enolase-2 serves as a valuable biomarker and has been detected in patients diagnosed with specific tumors, including neuroblastoma, small cell lung cancer, medullary thyroid cancer, carcinoid tumors, pancreatic endocrine tumors, and melanoma. ENO2 is one of three enolase isoenzymes found in mammals. The ENO2 isoenzyme is present in mature neurons and cells of neuronal origin. A transition from alpha enolase to gamma enolase takes place in neural tissue during the developmental stages of rats and primates.
