Effect of benzo(a)pyrene on the replication of vesicular stomatitis virus and transcriptomic analysis.
Benzo(a)pyrene (Bap), a key component of cigarette smoke (CS), is a pollutant and widely present in our daily life. The roles of Bap on viral replication have been amply discussed and controversial. In our present study, we investigated the effect and mechanism of Bap on the replication of vesicular stomatitis virus (VSV) and respiratory syncytial virus (RSV) in vitro. HeLa cells were pre-exposed to Bap at 10 µM for 48 h and then infected with VSV (MOI=1) for 24 h. RNA sequencing analysis was conducted to identify Bap-dysregulated genes and qPCR analysis was used to identify the result. Chronic exposed to Bap significantly inhibited the replication of VSV and RSV in vitro and in vivo. Overall design: HeLa cells were pre-exposed to 10 µM Bap for 48 h and then infected with VSV (MOI=1) for 24 h with continuous exposure to Bap.
