該研究利用CRISPR/Cas9(clustered regularly interspaced short palindromic repeats/CRISPR associated protein 9)基因編輯系統(tǒng)構(gòu)建了TP53(tumor antigen p53)基因敲除He La細(xì)胞系。CRISPR/Cas9系統(tǒng)能夠精確地切開(kāi)TP53基因并在雙鏈斷裂處插入選擇標(biāo)記(通過(guò)與供體質(zhì)粒進(jìn)行同源重組獲得)。進(jìn)一步的功能試驗(yàn)表明,TP53基因敲除的He La細(xì)胞擁有更強(qiáng)的細(xì)胞增殖能力、化療耐藥性以及氧化應(yīng)激能力,提示He La(TP53–/–)惡性程度增強(qiáng)。所有的數(shù)據(jù)旨在描述一個(gè)簡(jiǎn)單和有效的方法,即通過(guò)CRISPR/Cas9系統(tǒng)來(lái)構(gòu)建基因缺失細(xì)胞系,期望在較大程度上幫助研究和闡明基因功能以及細(xì)胞機(jī)制。
