摘要 脱氨神经氨酸(2-keto-3-deoxy-D-glycero-D-galacto-nononic acid,KDN)是唾液酸家族中的三种核心成员之一。KDN单体主要由甘露糖作为前体糖合成得到,KDN大量存在于低等脊椎动物和细菌中,而在哺乳动物中的表达量却很低。近期,有研究报道,KDN在人类肿瘤中高表达,并且会随着肿瘤恶性程度的增高呈正相关增长,因此,推测KDN可能是某些肿瘤的肿瘤标示物。本文介绍了KDN的结构及其生物合成,重点综述了KDN在生物体内及肿瘤中的表达等研究现状,为以后深入研究KDN奠定了良好的基础。 脱氨神经氨酸(2-keto-3-deoxy-D-glycero-D-galacto-nononic acid,KDN)是唾液酸家族中的三种核心成员之一。KDN单体主要由甘露糖作为前体糖合成得到,KDN大量存在于低等脊椎动物和细菌中,而在哺乳动物中的表达量却很低。近期,有研究报道,KDN在人类肿瘤中高表达,并且会随着肿瘤恶性程度的增高呈正相关增长,因此,推测KDN可能是某些肿瘤的肿瘤标示物。本文介绍了KDN的结构及其生物合成,重点综述了KDN在生物体内及肿瘤中的表达等研究现状,为以后深入研究KDN奠定了良好的基础。
