Gene expression patterns induced at different stages of rhinovirus infection in human alveolar epithelial cells

Gene expression analysis of the A549 cells infected with HRV.

Total RNA was extracted from both HRV-infected and mock-infected A549 cells and hybridized to GeneChip PrimeView GeneChip Arrays. (A) Hierarchical cluster and heat map analysis of HRV-affected genes. Horizontal clusters shows genes and clusters in the columns represent samples (samples represent by 1 and orange color are virus infected and samples show by 2 and in green represent mock-infected samples). The DEGs in response to HRV infection were filtered here at p-value ≤ 0.05 and with a fold change of two and above (One-Way Between-Subject ANOVA (unpaired)). Genes shown in red were up-regulated, while genes shown in green were down-regulated, in HRV-infected compared to mock-infected cells. (B) Summary of DE genes induced by HRV72. The DE genes were determined at four time points by filtering of the genes at p-value ≤ 0.05 and with a fold change of 1.5. (C) Venn diagram showing overlap of DEGs in HRV-infected cells compared with mock-infected A459 cells with 1.5-fold (p-value ≤ 0.05). (D) Number of overlap genes in different combination of time points are presented in the table.
