Multiple endorphins in neuronal hybrid cell lines.

Abstract
Neuroblastoma x glioma hybrid cells (NG 108CC15) and tumors derived thereof were examined for dynorphin- and alpha-neoendorphin-like material. The techniques employed for analyses of opiate-like material were the isolated mouse vas deferens bioassay and gel chromatography and high pressure liquid chromatography in combination with radioimmunoassays. Dynorphin- and alpha-neoendorphin-like material was detected in both the hybrid cells and the corresponding tumors. Immunoreactive dynorphin and alpha-neoendorphin was also in NCB 20 hybrid cells and in tumors thereof assayed. In all samples investigated, the amounts of alpha-neoendorphin-like material was higher than that of dynorphin-like material. The results revealed considerable variability in the amount of dynorphin- and alpha-neoendorphin-activity between particular samples, suggesting the need for studies into the responsible mechanisms.
