利用CRISPR/Cas9基因编辑系统构建TP53基因敲除HeLa细胞系(英文)
发布时间:2023-08-20 10:38
该研究利用CRISPR/Cas9(clustered regularly interspaced short palindromic repeats/CRISPR associated protein 9)基因编辑系统构建了TP53(tumor antigen p53)基因敲除He La细胞系。CRISPR/Cas9系统能够精确地切开TP53基因并在双链断裂处插入选择标记(通过与供体质粒进行同源重组获得)。进一步的功能试验表明,TP53基因敲除的He La细胞拥有更强的细胞增殖能力、化疗耐药性以及氧化应激能力,提示He La(TP53–/–)恶性程度增强。所有的数据旨在描述一个简单和有效的方法,即通过CRISPR/Cas9系统来构建基因缺失细胞系,期望在较大程度上帮助研究和阐明基因功能以及细胞机制。
