RNA from the cells was isolated with the RNAeasy mini kit (Qiagen, Hilden, Germany), and cDNA synthesis was performed. PCR was performed using qPCR master mix containing SYBR green with primers of GAPDH and pro-inflammatory molecules (IL-1β, IL-18, NLRP3) (Applied Biosystems 7500 Fast, Foster City, CA, USA) (Table 2). For the detection of miRNAs, miR-223 and endogenous control U6 primer assays were utilized (Qiagen, Hilden, Germany). The expression difference was analyzed by the ΔΔCt method with endogenous normalization to GAPDH or U6 [23 (link)].
