Project description:New alkyl-phospholipids (APLs) that are structurally derived from the platelet-activating factor are promising candidates for anticancer treatment. After the incorporation into cell membranes, APLs are able to interfere with a wide variety of key enzymes implicated in cell growth, motility, invasion and apoptosis. Recently, using Agilent cDNA microarray technology, we could demonstrate that the glycosidated APL Ino-C2-PAF inhibited the expression of several genes associated with immune response and inflammation in immortalized keratinocytes HaCaT. Here, we analyzed the impact of Ino-C2-PAF on the gene expression profile of HaCaT cells treated with several pro-inflammatory cytokines (IL-1M-NM-1, IL-17, IL-22, TNF-M-NM-1 and oncostatin-M). The influence of Ino-C2-PAF on the transcriptional profile of immortalized keratinocytes (HaCaT) was analyzed treating HaCaT cells with 5 M-BM-5M Ino-C2-PAF in the presence of a mixture of pro-inflammatory cytokines (IL-1M-NM-1, IL-17, IL-22, TNF-M-NM-1 and oncostatin-M) for 24 h. Control cells were left untreated. Three independent experiments were performed for each condition, except for control cells where only two experiments were performed. Control cells were mainly necessary to demonstrate the efficiency of this in vitro inflammation model for keratinocytes.

Project description:New alkyl-phospholipids (APLs) that are structurally derived from the platelet-activating factor are promising candidates for anticancer treatment. After the incorporation into cell membranes, APLs are able to interfere with a wide variety of key enzymes implicated in cell growth, motility, invasion and apoptosis. Besides the prototype edelfosine, we presented a novel group of APLs, glycosidated phospholipids that efficiently inhibit cell proliferation. Two members of this group, Ino-C2-PAF and Glc-PAF, display high efficacy and low cytotoxicity in immortalized non-tumorigenic skin keratinocyte cell line HaCaT. However, the influence of APLs on the transcription of the whole genome is still unknown. Here, using Agilent cDNA microarray technology, we compared global gene expression profiles of HaCaT cells treated with edelfosine, Ino-C2-PAF or Glc-PAF with the profile of control cells. The influence of APLs on the transcriptional profile of immortalized keratinocytes (HaCaT) was analyzed treating HaCaT cells with respectively 5 M-BM-5M Ino-C2-PAF, Glc-PAF and edelfosine for 24 h. Control cells were left untreated. Three independent experiments were performed for each condition.

Project description:This study evaluated the miRNA expression profile of human neutrophils under resting conditions and after stimulation with PAF and fMLP, applied alone or sequentially. The objective was to determine whether distinct inflammatory stimuli and their order of exposure induce different miRNA expression patterns in neutrophils. Neutrophils from healthy donors were assigned to five conditions: control, PAF, fMLP, PAF followed by fMLP (PF), and fMLP followed by PAF (FP). Total RNA was extracted and hybridized to the Affymetrix miRNA 4.0 Array platform for expression analysis.

Project description:Human neutrophils isolated from peripheral blood of five healthy male donors were analyzed by one-color microarray to investigate transcriptional changes induced by single and sequential stimulation with platelet-activating factor (PAF) and N-formyl-methionyl-leucyl-phenylalanine (fMLP). The experiment included five conditions: unstimulated control, PAF, fMLP, PAF followed by fMLP, and fMLP followed by PAF, totaling 25 samples. This design was used to evaluate whether the order of exposure to endogenous and exogenous inflammatory stimuli influences neutrophil transcriptional responses. Total RNA was extracted after stimulation and hybridized to the Clariom S Human Array according to the manufacturer’s protocol. The study aimed to characterize stimulus-dependent and order-dependent transcriptional profiles in human neutrophils.

Project description:Previous stimulation experiments of stimulated primary murine colonic fibroblasts with IL-36R ligands for 4h in vitro showed an upregulation of pro-inflammatory cytokines e.g. IL-6, IL-1b and chemokines e.g. CXCL1, CCL2 indicating an important role for IL-36 in inflammation. We were interested in analyzing long-term stimulation (9 days) of intestinal fibroblasts to identify a putative differential expression profile. The experimental setup included 6 samples from 3 colons in a pairwise design (3 stimulated vs 3 unstimulated).

Project description:Here, we aim to understand the role of P38 in the airway epithelial cells response to flagellin. We report the gene expression profile of pig airway epithelial cells cultured under air-liquid conditions, pre-incubated or not with the P38 inhibitor SB203580 (20 µM, Tocris Bioscience) for 1 h and then stimulated with 100 ng/ml of a mutated flagellin (FliCΔ174-400) for 2h or 24h. Our data show that flagellin stimulation induce the expression of pro-inflammatory cytokines mainly through the NFkB pathway, with little impact of P38 inhibition in the cells response.
