Human cytomegalovirus (HCMV) is a virus which has the potential to alter cellular gene expression through multiple mechanisms.
With the application of DNA microarrays, we could monitor the effects of pathogens on host-cell gene expression programmes in great depth and on a broad scale.
Changes in mRNA expression levels of human endothelial-like ECV304 cells following infection with human cytomegalovirus AD169 strain was analyzed by a microarray system comprising 21073 60-mer oligonucleotide probes which represent 18716 human genes or transcripts.
The results from cDNA microarray showed that there were 559 differential expressed genes consisted of 471 upregulated genes and 88 down-regulated genes. Real-time qPCR was performed to validate the expression of 6 selected genes (RPS24, MGC8721, SLC27A3, MST4, TRAF2 and LRRC28), and the results of which were consistent with those from the microarray. Among 237 biology processes, 39 biology processes were found to be related significantly to HCMV-infection. The signal transduction is the most significant biological process with the lowest p value (p=0.005) among all biological process which involved in response to HCMV infection.
Several of these gene products might play key roles in virus-induced pathogenesis. These findings may help to elucidate the pathogenic mechanisms of HCMV caused diseases. [This corrects the article on p. 243 in vol. 13, PMID: 24235919.].
人巨细胞病毒(HCMV)是一种有潜力通过多种机制改变细胞基因表达的病毒。
应用DNA微阵列,我们能够深入且广泛地监测病原体对宿主细胞基因表达程序的影响。
采用包含21073个60聚体寡核苷酸探针(代表18716个人类基因或转录本)的微阵列系统,分析人巨细胞病毒AD169株感染后人内皮样ECV304细胞mRNA表达水平的变化。
cDNA微阵列结果显示,有559个差异表达基因,其中471个上调基因,88个下调基因。进行实时定量PCR验证6个选定基因(RPS24、MGC8721、SLC27A3、MST4、TRAF2和LRRC28)的表达,其结果与微阵列结果一致。在237个生物学过程中,发现39个生物学过程与HCMV感染显著相关。信号转导是所有参与HCMV感染应答的生物学过程中p值最低(p = 0.005)的最显著生物学过程。
这些基因产物中的一些可能在病毒诱导的发病机制中起关键作用。这些发现可能有助于阐明HCMV所致疾病的致病机制。[这纠正了第13卷第243页的文章,PMID:24235919。]
