Next Generation Sequencing Facilitates Quantitative Analysis of Ern1f/f and Ern1f/fLyz2-Cre macrophage Transcriptomes

ABSTRACT: Purpose: IRE1 are indicated to play important role in LPS-induced macrophage activation. The goals of this study are to investigate the effects of IRE1a abrogation in macrophages on Interleukin-4-induced alernative activation of macrophages. Methods: Total cellular RNAs of M2-polarized BMDMs by IL-4 treatment were isolated and subjected to commercial RNA-seq analysis. RNA-seq data were uniquely mapped to mm10 reference genome by TopHat v1.4.1. Expression values were assigned to gene level by Cufflinks v1.3.0. Results: Map ratios of all RNA-seq samples were above 80%. Merged expression values of all samples included 10,863 genes. Principle component analysis showed distinguished patterns between groups. Conclusions: Our study represents detailed analysis of transcriptomes of IL-4-activated macrophages, with biologic replicates, generated by RNA-seq technology. Based on the analysis of our RNA-seq data, increased expression levels of marker genes of macrophage alternative activation were found in IRE1a-abrogated macrophages copared to control cells. Our results demonstrates the loss of ER stress sensor IRE1a in macrophages enhanced IL-4-induced alternative activation.

Histone Deacetylase 3 is an Epigenomic Brake in Macrophage Alternative Activation (microarray)

Project description:Macrophages, a key cellular component of inflammation, become functionally polarized in a signal- and context-specific manner. Th2 cytokines such as IL-4 polarize macrophages to a state of alternative activation that limits inflammation and promotes wound healing. Alternative activation is mediated by a transcriptional program that is influenced by epigenomic modifications including histone acetylation. To determine if Histone Deacetylase 3 (HDAC3) has a role in macrophage polarization including alternative activation, we have performed global gene expression analysis in macrophages with and without HDAC3 and with or without IL-4 exposure. From this data, we conclude that macrophages lacking histone deacetylase 3 (HDAC3) display a polarization phenotype similar to IL-4 induced alternative activation and furthermore are hyper-responsive to IL-4 stimulation. Mouse bone marrow derived macrophages were obtained from both control and HDAC3 KO animals and treated with vehicle control (BSA) or IL-4 for 24 hours. RNA was isolated and subjected to analysis using an Agilent Whole Genome Microarray Kit.

Genome-wide analysis of mouse macrophages stimulated with IL-4 (Biogel and thioglycollate macrophages) (Affymetrix)

Project description:Analysis of alternative activation of macrophages at gene expression level. The study forms part of a wider study where we compare the effects of IL-4 in different human and mouse macrophages. Our results support the notion that in vitro culture conditions greatly affect the macrophage response to IL-4. Total RNA obtained from Thioglycollate and Biogel elicited peritoneal macrophages exposed to 20 ng/ml of IL-4 for 18 hours. Biogel and thioglycollate elicited macrophages were stimulated with the Th2 cytokine IL-4, for RNA extraction and hybridization on Affymetrix microarrays.

Genome-wide analysis of human macrophages stimulated with IL-4 (10ng/ml) (Illumina)

Project description:Analysis of alternative activation of macrophages at gene expression level. The study forms part of a wider study where we compare the effects of IL-4 in different human and mouse macrophages. Our results support the notion that in vitro culture conditions greatly affect the macrophage response to IL-4. Total RNA obtained from human monocyte derived macrophages upon exposure to 10 ng/ml of IL-4 for 48 hours. Monocytes were induced to mature into macrophages using X Vivo 10 medium supplemented with 1% autologous serum.

MicroRNA expression in thioglycollate and alternatively activated

Project description:Macrophage activation must be tightly controlled to prevent overzealous responses that cause self-damage. MicroRNAs have been shown to promote classical macrophage activation by blocking concomitant anti-inflammatory signals and transcription factors, but can also place restraints on activation by preventing excessive TLR-signalling. In contrast, the microRNA profile associated with alternatively activated macrophages and their role in regulating wound-healing or anti-helminthic responses has not yet been described. Utilizing an in vivo model of alternative activation, in which adult Brugia malayi nematodes are surgically implanted in the peritoneal cavity of mice, we examined the profile of microRNA expression in these alternatively activated macrophages and compared this to alternatively activated IL-4 receptor knockout macrophages and thioglycollate elicited macrophages. Peritoneal macrophages from BALB/c wild type or IL-4 receptor knockout mice were elicited with thioglycollate or using nemtodes (peritoneal implant of Brugia malayi). The latter leads to a population of alternatively activated macrophages. Microarray analysis was used to examine the microRNA profile of WT alternatively activated macrophages (n = 4), IL-4 receptor knockout alternatively activated macrophages (n = 4), WT thioglycollate elicited macrophages (n = 3) and IL-4 receptor knockout thioglycollate elicited macrophages (n = 3).
