The L-myc, N-myc and c-myc genes are members of the myc oncogene family. In particular, L-myc is novel, and amplification of L-myc is still unknown except in small cell lung carcinoma. We examined L-myc amplification in 30 human neuroblastomas using Southern blot hybridization, and found that the L-myc gene was amplified approximately 5-fold in GOTO, a human neuroblastoma cell line. The N-myc gene was also amplified approximately 60-fold and furthermore, over-expression of L-myc and N-myc genes was observed in this cell line. In this report, we describe the coamplification of the myc gene family in the GOTO neuroblastoma cell line.
L-myc、N-myc和c-myc基因是myc癌基因家族的成员。特别是,L-myc是新发现的,除在小细胞肺癌中外,L-myc的扩增情况仍不明确。我们使用Southern印迹杂交法检测了30例人类神经母细胞瘤中的L-myc扩增情况,发现L-myc基因在人类神经母细胞瘤细胞系GOTO中扩增了约5倍。N-myc基因也扩增了约60倍,此外,在该细胞系中还观察到L-myc和N-myc基因的过表达。在本报告中,我们描述了GOTO神经母细胞瘤细胞系中myc基因家族的共扩增情况。
