To better understand the mechanisms of miRNAs in PUFA-modulated cellular pathways, we compared physical signs and immune statuses of PUFA-treated rats. The results indicated that omega-3 PUFAs decreased production of pro-inflammatory cytokines such as interleukin-6, C-reactive protein, and tumor necrosis factor-a, at the same time, increased proportion of CD8+ suppressor T cells and regulatory T cells in rats. The changes of these biological parameters showed that the PUFA diet-induced autoimmune (AI)-prone and AI-averse rat models were successfully established. As following steps, differentially expressed miRNAs were filtered in peripheral serum by microarray assay and validated in PBMC, liver, visceral fat, and pituitary gland by stem-loop real-time quantitative-PCR (RT-qPCR). Biological databases and computational algorithms were used to classify the potential target genes of these PUFA-induced differentially expressed miRNAs.
