ABSTRACT: Methods: Methods: To better understand the role of resveratrol in the regulation of neutrophils activation and function, neutrophils with or without resveratrol in the expose of LPS were compared in a transcriptome sequencing study. Total RNA was isolated from bone marrow and FACS-separated neutrophils. Transcriptome sequencing libraries were generated using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB, USA) following manufacturer’s recommendations and sequenced on an Illumina Hiseq platform (Illumina, San Diego, CA). Sequences were aligned to the reference genome with TopHat and processed with Cufflinks, which quantifies each transcript in each sample using reference annotations produced bythe University of California Santa Cruz UCSC. Differentially expressed genes with a fold change of >=2.0 and p value<0.01 between resveratrol treated and control neutrophils were submitted to GO and KEGG enrichment analysis, which uses unbiased methods to assess pathway enrichment. Results: Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses revealed that downregulated genes from resveratrol-stimulated neutrophils are involved in neutrophil migration, neutrophil chemotaxis, TNF signaling pathway and cytokine activity, among other. Compared to control neutrophils, neutrophils with resveratrol exhibited downregulated levels of cell survival related genes (Camkk1, Aqp1, Bcl2a1b, etc), cell cycle related genes (Ccnb1, Ccnb2, Cdc20, Cdk1, etc), adhesion and migration related genes (Cass4, Nectin4, Gp5, Gpr35, etc), and cytokines (Csf1, Csf3, Ccl2, Ccl7, Ccl12).
