Sequencing of F4/40+ CD11b+ macrophages from adipose tissue of miR-146a WT or deficient mice on high fat or normal chow diet

We identify regulatory mechanisms that influence inflammation and metabolism during metabolic disease development. In addition to the other data represented in our paper, we performed RNA-seq to demonstrate a role for miR-146a, an anti-inflammatory miRNA, in regulating both inflammation and cellular metabolism during obesity. Overall design: Each sample represents pooled cells from three mice of the same genotype and treatment group. Samples were pooled before FACS to ensure sufficient cell numbers for sorting and RNA collection. WT or miR-146a-/- mice were treated with either high fat diet or normal chow diet for 14 weeks starting from 6 weeks of age. Mice were sacrificed and live, singlet CD45+ CD11b+ F4/80+ cells were sorted from the stromal vascular fraction of adipose tissue using FACS Aria. RNA was collected from the sorted cells via Qiazol/RNeasy Kit (Qiagen) and library preparation used Illumina TruSeq Stranded RNA Kit with Ribo-Zero Gold. RNA-seq was performed using Illumina HiSeq 50 cycle single-read sequencing version 4. Sequence alignment was performed through the University of Utah Bioinformatics Core Facility.
