Transcriptional Profiling of B19 Virus Nonstructure Protein (NS1) transduced CD36+ Erythoid Progenitor Cells (EPCs)

B19V NS1 is known to be cytotoxic and involved in the pathogenesis of B19V infection. Our previous data demonstrated that NS1 impaired the cell-cycle progression of the CD36+ EPCs by inducing a stable G2 arrest. Microarray analysis was used to identify genes whose expressions were associated with the NS1-induced G2 arrest. A total of 1045 genes displayed a more than 1.5-fold differential expression in the NS1-transduced cells. Out of 1045 differentially expressed genes, 177 were involved in cell-cycle regulation and 51 were involved in the regulation of cell differentiation.
