Macrophage migrasomes (M-mig) gene profiling

ABSTRACT: In the present study, we have documented a previously unrecognized membrane vesicles called “migrasomes” (M-mig) that originate from the filament-like nanotubes of macrophage.To characterize the signatures of macrophage migrasomes (M-mig) gene expression that might underlie M-mig-associated biological function. M0-mig, M1-mig, M2-mig and HG-mig genome-wide expression profiling was carried out by using SurePrint G3 Mouse GE V2.0 8X60K Microarrays (Design ID:074809, Agilent Technologies, USA). Total RNA was quantified by the NanoDrop ND-2000 (Thermo Scientific) and the RNA integrity was assessed using Agilent Bioanalyzer 2100 (Agilent Technologies). The sample labeling, microarray hybridization and washing were performed based on the manufacturer’s standard protocols. Briefly, total RNA was transcribed to double strand cDNA, then synthesized into cRNA and labeled with Cyanine-3-CTP. The labeled cRNAs were hybridized onto the microarray. After washing, the arrays were scanned by the Agilent Scanner G2505C (Agilent Technologies). For data analysis, Feature Extraction software (version10.7.1.1, Agilent Technologies) was used to analyze array images to get raw data. Genespring (version14.9, Agilent Technologies) were employed to finish the basic analysis with the raw data. To begin with, the raw data was normalized with the quantile algorithm. Differentially expressed genes were then identified through fold change. The threshold set for up- and down-regulated genes was a fold change>=2.0. Afterwards, GO analysis and KEGG analysis were applied to determine the roles of these differentially expressed mRNAs.
