A series of 22 neuroepithelioma and neuroblastoma cell lines were screened for expression of nerve growth factor receptor (NGFR) by flow cytometry, Western blotting, and Northern blotting. All 5 neuroepithelioma cell lines expressed cell surface NGFR, with 30-69% of cells NGFR positive, but the 17 neuroblastoma cell lines tested had a smaller percentage of cell surface NGFR-positive cells (0-21%) and 10 lines were completely lacking cell surface NGFR. SY5Y, a variant line with a neuronal phenotype derived from neuroblastoma line SKNSH, expressed much more NGFR than SHEP, a variant line with an epithelial-like phenotype also derived from SKNSH. By Western blotting, the Mr approximately 69,000 NGFR band was detected for all four neuroepithelioma cell lines tested but was visible for only 8 of 15 neuroblastoma cell lines tested. The band was most intense for neuroepithelioma cell lines SKNMC and TC32. For these two lines, a Mr approximately 56,000 and a Mr approximately 60,000 band were also detected. By Northern blotting, all three neuroepithelioma cell lines tested were positive for the 3.8 kilobase NGFR mRNA, but only 8 of 15 neuroblastoma cell lines were positive. Neuroepithelioma cell line TC32 and neuroblastoma cell line GICAN had the strongest expression of NGFR mRNA. These results demonstrate that NGFR is a biological marker for neuroepithelioma and that NGFR expression is heterogeneous for neuroblastoma cell lines. This series of neural cell lines differing in NGFR expression will be useful for future studies of regulation of NGFR expression and neuronal differentiation.

D009447 Neuroblastoma A common neoplasm of early childhood arising from neural crest cells in the sympathetic nervous system, and characterized by diverse clinical behavior, ranging from spontaneous remission to rapid metastatic progression and death. This tumor is the most common intraabdominal malignancy of childhood, but it may also arise from thorax, neck, or rarely occur in the central nervous system. Histologic features include uniform round cells with hyperchromatic nuclei arranged in nests and separated by fibrovascular septa. Neuroblastomas may be associated with the opsoclonus-myoclonus syndrome.

D011519 Proto-Oncogenes Normal cellular genes homologous to viral oncogenes. The products of proto-oncogenes are important regulators of biological processes and appear to be involved in the events that serve to maintain the ordered procession through the cell cycle. Proto-oncogenes have names of the form c-onc. Proto-Oncogene,Proto Oncogene,Proto Oncogenes
D011956 Receptors, Cell Surface Cell surface proteins that bind signalling molecules external to the cell with high affinity and convert this extracellular event into one or more intracellular signals that alter the behavior of the target cell (From Alberts, Molecular Biology of the Cell, 2nd ed, pp693-5). Cell surface receptors, unlike enzymes, do not chemically alter their ligands.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
