The aim of the present study was to characterize the gene expression profile of the phosphodiesterase-4 inhibitor CHF6001 on top of inhaled triple therapy in sputum cells and whole blood of chronic bronchitis patients. Samples for analyses were collected from a multicenter, three-period, three-way, placebo-controlled, double-blind, complete block crossover study. Eligible patients underwent three, 32-day treatment periods during which they received CHF6001 800 or 1600 µg twice daily (total daily doses of 1600 or 3200 µg) or matching placebo, all via multi-dose dry-powder inhaler (NEXThaler). Treatment periods were separated by a 28–42 day washout. Eligible patients were male or female, ≥40 years of age, current or ex-smokers with a smoking history ≥10 pack-years, a diagnosis of COPD, post-bronchodilator forced expiratory volume in 1 second (FEV1) ≥30% and <70% predicted, ratio of FEV1 to forced vital capacity (FVC) <0.70, COPD Assessment Test score ≥10, and a history of chronic bronchitis (defined as chronic cough and sputum production for more than three months per year for at least two years) and treated with inhaled triple ICS/LABA/LAMA therapy for at least two months prior to enrollment. CHF6001 had no effect in blood, but a strong effect in sputum with 1471 and 2598 significantly differentially-expressed probe-sets relative to placebo (p-value adjusted for False Discovery Rate<0.05) for 800 and 1600µg , respectively. Functional enrichment analysis showed significant modulation of key inflammatory pathways involved in cytokine activity, pathogen-associated-pattern-recognition activity, oxidative stress and vitamin D with associated inhibition of downstream inflammatory effectors. A large number of pro-inflammatory genes coding for cytokines and matrix-metalloproteinases were significantly differentially expressed for both doses; the majority (>87%) were downregulated, including macrophage inflammatory protein-1-alpha and 1-beta, interleukin-27-beta, interleukin-12-beta, interleukin-32, tumor necrosis factor-alpha-induced-protein-8, ligand-superfamily-member-15, and matrix-metalloproteinases-7,12 and 14. In conclusion inhaled PDE4-Inhibition by CHF6001 on top of triple therapy in patients with chronic bronchitis patients significantly modulated key inflammatory targets and pathways in the lung but not in blood. Mechanistically these findings support a targeted effect in the lung while minimizing unwanted systemic class-effects

View SamplesWe report that phosphorylated ribosomes can be immunoprecipitated from mouse brain homogenates, resulting in enrichment of transcripts expressed in activated neurons. Overall design: Mice were either injected with a concentrated salt solution or vehicle, hypothalami dissected, and phosphorylated ribosomes immunoprecipitated. RNA was sequenced from the input and IP for each condition (4 samples total).

View SamplesRNA sequencing libraries were made for A-498 and 786-O to detect the transcripts regulated by the lincRNA comparing knockdown and the non-targeting control. Overall design: Two siRNAs were designed, non-target control and the siRNAs were introduced to the cell lines A-498 and 786-O separately by Lipofectamine 2000. After 16 hours total RNA were extracted. Barcoded cDNA libraries were then prepared from total RNA using the Illumina TruSeq RNAseq kit, and sequenced (single-end 36-bp reads) on an Illumina HiSeq instrument.

View SamplesThe experiment aimed at determing the influence of mast cell deficiency on the transcriptome of skin-infiltrating leukocytes in K14HPV16 mice at 2month and 6month of age. Overall design: Skin-inflitrating leucocytes were FACS-purified from mast cell proficient (Mcpt5-Cre-) and mast cell deficient (Mcpt5-Cre+) K14HPV16 mice. Mast cells (CD117 high, FCeR1 high) were excluded from the sorting gate. In order to control for minimal mast cell contamination during sorting from K14HPV16 Mcpt5-Cre- skin, mast cell signature transcripts were identified by comparing transcriptomes of samples fromK14HPV16 Mcpt5-Cre- mice in which mast cells were flow cytometrically included vs excluded.

View SamplesRNA seq was used to compare the expression profile of macrophages in presence and absense of mast cells. MB49 cells were injected i.d. into Mcpt5-Cre+ R26DTA animals and cre-negative littermates. Macrophages were sorted at 20 d.p.i. Overall design: Macrophage RNA profiles of MB49 TAMs (tumor-associated macrophages), harvested at 20 d.p.i. in MC-Proficient and MC-deficient animals

View SamplesWe report that previously described molecular subtypes of colorectal cancer are associated with the response to therapy in patients with metastatic disease. We also identified a patient population with high FOLFIRI sensitivity, as indicated by their 2.7-fold longer overall survival when treated with FOLFIRI, as first-line regimen, instead of FOLFOX. Our results demonstrate the interest of molecular classifications to develop tailored therapies for patients with metastatic colorectal cancer.
