Chromosome manipulation is a useful technique in biological science. We have constructed human artificial chromosomes (HACs) based on the transfection of centromeric alphoid DNA precursors into cultured human cells. Moreover, HAC-based technology has been developed into a novel gene expression vector tool for introducing large-size genomic DNA. This technique provides natural expression, as well as stable expression without the gene silencing that often occurs with conventional vectors in mammalian cells. Here we review the properties of HACs, and issues regarding the use of HAC technology for basic and applied research.

自下而上的人类人工染色体在细胞研究和细胞工程中的应用。

染色体操纵是生物科学中的一种有用技术。我们已经建立了人类人工染色体(HACs),其基础是将着丝粒的Alphoid DNA前体转染到培养的人类细胞中。此外,基于HAC的技术已经发展成为一种新型的基因表达载体工具,用于引入大尺寸的基因组DNA。该技术提供了自然表达以及稳定表达,而没有哺乳动物载体中常规载体经常发生的基因沉默。在这里,我们回顾了HAC的特性,以及有关在基础研究和应用研究中使用HAC技术的问题。
