8-oxoG RNA IP data set 2: Air pollution mixture derived from the reaction of 100 ppb acrolein, 97 ppb methacrolein, 44 ppb alpha-pinene and 100 ppb O3 for 1.5 h

While environmental agents such as air pollution have been shown to be causative to diseases, yet limited knowledge exist on their mechanism of action. Here we used RNA-sequencing in combination with specific immunoprecipitation of 8-oxo-7,8-dihydroguanosine (8-oxoG) to identify transcripts accumulating oxidation after exposure to air pollution (derived from the reaction of acrolein, methacrolein, alpha-pinene and ozone) in bronchial epithelial BEAS-2B cells. Results from this analysis suggest a functional role of the 8-oxoG modified transcripts after air pollution exposure in pathways that are central regulators of cell metabolism, growth, proliferation and maintenance of cellular structure. This study highlights a critical role for a RNA epitranscriptomics modification that can be used to further characterize biological responses to external stressors once considered indistinguishable. Overall design: 8-oxoG was measured from rRNA depleted RNA in BEAS-2B cells exposed to air pollution mixtures (derived from the reaction of 100 ppb acrolein, 97 ppb methacrolein, 44 ppb alpha-pinene and 100 ppb O3) and clean air for 1.5 hours. Two biological replicates are available from control input, and two biological replicates for IP 8-oxoG RNA.
