Gene expression data from CD14++ CD16- classical monocytes from healthy volunteers and patients with pancreatic ductal adenocarcinoma

ABSTRACT: Transcriptomic profiling of peripheral immune cells can provide a wealth of information. Classical CD14++ CD16- monocytes were isolated from the peripheral blood of healthy volunteers and patients with pancreatic ductal adenocarcinoma and profiled for differential gene expression using Affymetrix human Genechips 2.1 U133. Differentially expressed genes were identified comparing gene expression profiles between healthy and PDAC.

Clinical and molecular characteristics indicate mitochondrial dysfunction in Charcot-Marie-Tooth families with the AARS1 Arg326Trp mutation

Project description:Introduction Aminoacyl tRNA-synthetases are ubiquitously expressed enzymes that attach amino acids to their cognate tRNA molecule. Mutations in several of the aminoacyl tRNA-syntheases are described to cause peripheral neuropathy, i.e. AARS1, GARS1, HARS1, YARS1 and WARS1. The Alanyl-tRNA Synthetase (AARS) is encoded by the AARS1. Bi-allelic mutations have been described responsible for epileptic encephalopathy with persistent myelination defect, while mutation in a single allele cause Charcot-Marie-Tooth disease type 2 (CMT2). Do date it is uncertain how a single AARS1 mutation cause tissue specific neuropathy. Methods The AARS1 was sequenced by next-generation sequencing in probands. Family members were examined by Sanger sequencing. Blood samples from affected and healthy controls were used for quantitative RNA analysis, biochemical analysis of alanine, and proteomics. Results Three Norwegian CMT2 families carried the same novel heterozygous AARS1 variant (NM_001605.2:c.976C>T p.(Arg326Trp)). The three families consisted of in total 17 genetically examined family members, of which 11 individuals carried the AARS1 variant and six unaffected individuals did not carry the variant. All individuals carrying the AARS1 variant presented with a mild to moderately severe CMT2 phenotype with adult onset, except a man age 91 years (reported by his son). Label-free quantitative proteomic analysis of four affected individuals pointed towards an effect on the immune system, comprising proteins known to represent components of systemic response to chronic injury and inflammation. Interestingly, a wide-spread impact on mitochondrial dysfunction was identified. Specifically, the oxidative phosphorylation complexes I, IV and V were highly downregulated. Conclusion Three Norwegian CMT2 families with an AARS1 variant, suggests mitochondrial dysfunction in AARS1 neuropathy.

gene expression Fulminant type 1 diabetes vs classical type 1A diabetes vs healthy controls

Project description:We determined the genes that were differentially expressed between fulminant type 1 diabetes and classical type 1A diabetes or healthy control using gene expression microarray in peripheral blood cells. Ten patients with type 1 diabetes (5 fulminant and 5 classical type 1A) and 6 healthy controls were enrolled in this study. All patients had recovered from ketosis or ketoacidosis at disease onset and had been receiving intensive insulin injection therapy for at least 1 month, which means that all patients and healthy controls were free of metabolic derangements at the time of blood sampling. To determine the genes that were differentially expressed among fulminant type 1 diabetes, classical type 1A and healthy controls, a volcano plot analysis (fold change >1.5 and p-value <0.05) was performed.

Gene expression profiling of the classical (CD14++CD16-), intermediate (CD14++CD16+) and nonclassical (CD14+CD16+) human monocyte subsets

Project description:The new official nomenclature subdivides human monocytes into three subsets, classical (CD14++CD16-), intermediate (CD14++CD16+) and nonclassical (CD14+CD16+). Here, we comprehensively define relationships and unique characteristics of the three human monocyte subsets using microarray and flow cytometry analysis. Our analysis revealed that the intermediate and nonclassical monocyte subsets were most closely related. For the intermediate subset, majority of genes and surface markers were expressed at an intermediary level between the classical and nonclassical subset. There features therefore indicate a close and direct lineage relationship between the intermediate and nonclassical subset. From gene expression profiles, we define unique characteristics for each monocyte subset. Classical monocytes were functionally versatile, due to the expression of a wide range of sensing receptors and several members of the AP-1 transcription factor family. The intermediate subset was distinguished by high expression of MHC class II associated genes. The nonclassical subset were most highly differentiated and defined by genes involved in cytoskeleton rearrangement that explains their highly motile patrolling behavior in vivo. Additionally, we identify unique surface markers, CLEC4D, IL-13RA1 for classical, GFRA2, CLEC10A for intermediate and GPR44 for nonclassical. Our study hence defines the fundamental features of monocyte subsets necessary for future research on monocyte heterogeneity. Three human monocyte subsets, the CD14++CD16- classical, the CD14++CD16+ intermediate and CD14+CD16+ nonclassical subsets were purified using fluorescence activated cell sorting from peripheral blood mononuclear cells. RNA was processed from the three monocyte subsets from 4 individual donors in duplicates, giving a total of 24 samples.
