摘要: LASS基因家族是一组高度保守的长寿基因。LASS基因所编码蛋白质均具有神经酰胺合 成酶活性,可合成不同种类的神经酰胺。神经酰胺是肿瘤细胞生长、信号转导等方面的关键中间体,据 此推测 LASS基因的表达可一定范围内抑制肿瘤的发生和发展。

关键词: 神经酰胺类, 基因, 肿瘤抑制, 肿瘤形成过程

Abstract: LASS gene family is a group of highly conserved and longevous gene LASS protein has a ceramide synthase activity, which can synthesize different types of ceramides. Ceramide is a key intermediate in tumor cells growth, signal transduction and other aspects. Thus it is inferred that the expression of LASS gene can suppress the occurrence and development of tumor within a certain range.

Key words: Ceramides, Genes, tumor suppressor, Neoplastic process
