Project description:We have carried out global gene expression analysis to clarify the interrelationship between 1,25-dihydroxyvitamin D3 and differentiation-driven gene expression patterns in developing human monocyte-derived dendritic cells. Monocytes were treated with 10 nM 1,25-dihydroxyvitamin D3 or vehicle 14 hours after plating for 12 hours or 5 days. Monocytes, differentiating dendritic cells (+/-1,25-dihydroxyvitamin D3 for 12 hours) and immature dendritic cells (+/-1,25-dihydroxyvitamin D3 for 5 days) were harvested. This design allows one to identify genes regulated by differentiation and/or 1,25-dihydroxyvitamin D3 in human monocyte-derived dendritic cells.

Project description:To examine the miRNA changes that occur during macrophage and dendritic cell differentiation we used the miRCURY LNATM microRNA Array (7th Gen) to profile monocyte-derived macrophages and monocyte-derived dendritic cells. Of the 2046 probes present on the assay, we detected expression of ~400 (20%) miRNAs across all samples.

Project description:Identification of MEK-ERK or p38MAPK dependent genes in human monocyte derived dendritic cells. Dendritic cells (DC) promote tolerance or immunity depending on their maturation state. Previous studies have revealed that DC maturation is enhanced or accelerated upon MEK-ERK signaling pathway inhibition. We have now determined the contribution of MEK-ERK activation to the profile of gene expression of human immature monocyte-derived dendritic cells (MDDC) and peripheral blood myeloid DC. ERK inhibition altered the expression of genes that mediate CCL19-directed migration (CCR7) and LDL binding (CD36, SCARB1, OLR1, CXCL16) by immature DC. Besides, ERK upregulated CCL2 expression while impaired the expression of DC maturation markers (RUNX3, ITGB7, IDO1). MEK-ERK-regulated genes exhibited an over-representation of cognate sequences for the Aryl Hydrocarbon Receptor (AhR) transcription factor, and we show that AhR mediates some of the ERK-dependent transcriptional effects in DC. Therefore, MEK-ERK signaling pathway regulates antigen capture, lymph node homing and the acquisition of maturation-associated genes, and its contribution to the maintenance of the immature state of MDDC and myeloid DC is partly dependent on the activity of AhR. Since pharmacological modulation of the MEK-ERK signaling pathway has been proposed as a potential therapeutic strategy for cancer, our findings indicate that ERK inhibitors might influence the generation of anti-tumor responses through regulation of critical DC effector functions. Human peripheral blood monocytes from three independent healthy donors (DC4, DC5 and DC7) were isolated by anti-CD14-labeled magnetic microbeads. CD14+ monocytes were cultured for 5 days in RPMI 10% FCS containing GM-CSF and IL-4 to generate immature monocyte-derived dendritic cells (MDDC). Immature MDDC were exposed to MEK inhibitor, U0126, or p38MAPK inhibitor, SB203580 for 1 hour and a final dose of GM-CSF and IL-4 were added to the culture. Cells were collected for analysis after 4, 10 or 24 hours.Total RNA from each condition was extracted using the All prep DNA/RNA/protein mini kit (Qiagen) and hybridized to an Agilent Human Whole Genome (4x44) Oligo Microarray. All experimental procedures were performed following manufacturer instructions.

Experiment Overall Design: Human monocytes were obtained from buffy coats from healthy donors by Ficoll gradient centrifugation followed by immunomagnetic cell separation with anti-CD14-conjugated microbeads. Monocytes were cultured in RPMI-1640 supplemented with 10% FBS, 800 U/ml GM-CSF and 500 U/ml IL-4. Monocytes were treated with 10 nM 1,25-dihydroxyvitamin D3 or vehicle 14 hours after plating for 12 hours or 5 days. Monocytes, differentiating dendritic cells (+/-1,25-dihydroxyvitamin D3 for 12 hours) and immature dendritic cells (+/-1,25-dihydroxyvitamin D3 for 5 days) were harvested. Experiments were performed in biological triplicates representing samples from different donors. 15 samples were processed and hybridized to Human Genome U133 Plus 2.0 Arrays.

Project description:We performed RNA-seq experiments on 14 samples to identify differential expressed genes between MelanA- and caIKK-treated monocyte-derived dendritic cells (DCs). DCs electroporated with RNA encoding melanoma antigen recognized by T cells 1 (MelanA) were used as control, and DCs electroporated with RNA encoding constitutively active IKKβ (caIKK) were used as case.
