感染时的细胞周期位置对人巨细胞病毒(HCMV)基因表达有深远的影响,因此需要在HCMV实验的设计和控制中加以考虑。虽然G 0/G1细胞支持病毒转录的立即开始,但通过S和G2细胞周期阶段的细胞阻止HCMV进入裂解复制周期。在这里,我们提供了两个快速和可靠的协议,允许一个确定指定的宿主细胞的细胞周期分布和监测病毒蛋白表达作为细胞周期状态的函数。这两种方法都利用胸苷类似物5-乙炔基-2 ′-脱氧尿苷和“点击”化学以温和和敏感的方式标记HCMV非允许S期细胞。
The cell cycle position at the time of infection has a profound influence on human cytomegalovirus (HCMV) gene expression and therefore needs consideration in the design and control of HCMV experiments. While G0/G1 cells support the immediate onset of viral transcription, cells progressing through the S and G2 cell cycle phases prevent HCMV from entering the lytic replication cycle. Here, we provide two fast and reliable protocols that allow one to determine the cell cycle distribution of the designated host cells and monitor viral protein expression as a function of the cell cycle state. Both protocols make use of the thymidine analogue 5-ethynyl-2′-deoxyuridine and “click” chemistry to label HCMV-non-permissive S phase cells in a gentle and sensitive way.
