Total RNA was extracted from the BV-2 cells of different treatment groups using the EZ-Press RNA purification kit (EZ Bioscience, Roseville, CA, USA). Then, a Reverse Transcription Kit (EZ Bioscience, Roseville, CA, USA) was used to convert the extracted RNA into cDNA using specific primers (EZ Bioscience, Roseville, CA, USA) to amplify the cDNA templates. The mRNA levels of various genes (COX2, TNF-α, IL-1β, and IL-6) compared with GAPDH were evaluated by 2−ΔΔCt. The primer sequences used in this study refer to previous studies [52 (link),53 (link),54 (link)] (Table 1).
