Transcription levels of cytokines in lung tissues. (a–d) Transcription levels of TNF-α, IL-6, IFN-β, and TGF-β in the lung. Total RNA was extracted from lung tissues, and relative RT-qPCR detection was performed for each cytokine gene. GAPDH was the housekeeping gene, and the results were expressed as 2^−ΔΔCT. , , .
