P53 maintains gallid alpha herpesvirus 1 replication by direct regulation of nucleotide metabolism and ATP synthesis through its target genes.

ABSTRACT: P53, a well-known tumor suppressor, has been confirmed to regulate the infection of various viruses, including chicken viruses. Our previous study observed antiviral effect of p53 inhibitor Pifithrin-α (PFT-α) on the infection of avian infectious laryngotracheitis virus (ILTV), one of the major avian viruses economically significant to the poultry industry globally. However, the potential link between this antiviral effect of PFT-α and p53 remains unclear. Using chicken LMH cell line which is permissive for ILTV infection as model, we explore the effects of p53 on ILTV replication and its underlying molecular mechanism based on genome-wide transcriptome analysis of genes with p53 binding sites. The putative p53 target genes were validated by ChIP-qPCR and RT-qPCR. Results demonstrated that
