Description
A deficiency in cystic fibrosis transmembrane conductance regulator (CFTR) function in cystic fibrosis (CF) leads to chronic lung disease. However, the molecular mechanisms are not well understood and therapies that can help all patients remain elusive. CF is associated with abnormalities in fatty acids, ceramides and cholesterol, therefore we examined the impact of CFTR deficiency on lipid metabolism and pro-inflammatory signaling in airway epithelium using mass spectrometric, protein array and RNAseq analyses. We observed a striking imbalance in fatty acid and ceramide metabolism, associated with chronic oxidative stress under basal conditions in CF mouse lung and well differentiated bronchial epithelial cell cultures of CFTR knock out pig and CF patients. Cell autonomous features of all three CF models included high ratios of ω-6- to ω-3-polyunsaturated fatty acids and long- to very long- chain ceramide species (LCC/VLCC). The anti-oxidants glutathione (GSH) and deferoxamine partially corrected the lipid profile indicating that oxidative stress may promote the lipid abnormalities. CFTR-targeted modulators reduced the lipid imbalance and apparent oxidative stress, confirming the CFTR dependence of lipid ratios. RNA sequencing and protein array analysis revealed higher expression and shedding of cytokines and growth factors from CF epithelial cells compared to non-CF cells, consistent with sterile inflammation and tissue remodeling under basal conditions. Treatment with antioxidants or CFTR modulators that mimic the approved combination therapies, Orkambi and Trikafta, did not suppress the inflammatory phenotype. These results suggest that anti-inflammatory therapies may provide additional benefit for CF patients taking CFTR modulator drugs. Overall design: Here we report analysis of nine samples, three of Cf patient (BCF000174), homozygous for F508del CFTR, compared to two non-CF in triplicate each (P21, P11, ErasmusMC, Rotterdam, compared pairwise)

Description
miRNA-1343 is an uncharacterized miRNA predicted to target a number of genes involved in epithelial cell function including TGF-beta signaling, cell adhesion, and cell proliferation. We transiently overexpressed miRNA-1343 or a non-targeting control miRNA in A549 and 16HBE14o- human airway cell lines. As predicted, RNA-seq following miRNA-1343 overexpression showed significant downregulation of genes involved in these pathways. Furthermore, genes involved in cholesterol and lipid biosynthesis were found to be significantly upregulated by miRNA-1343 overexpression. Overall design: mRNA profiles from A549 and 16HBE14o- cells transiently transfected with miRNA-1343 or a negative control (NC) miRNA, in quintuplicate.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
ARC (NSC 188491, SMA-491), 4-amino-6-hydrazino-7-beta-d-ribofuranosyl-7H-pyrrolo-(2,3-d)-pyrimidine-5-carboxamide, is a nucleoside analog with profound in vitro anti-cancer activity. First identified in a high-throughput screen for inhibitors of p21 mRNA expression, subsequent experiments showed that ARC also repressed expression of hdm2 and survivin, leading to its classification as a global inhibitor of transcription 1. The following Hu U133 plus 2.0 arrays represent single time point (24 hour) gene expression analysis of transcripts altered by ARC treatment. Arrays for the other compounds (sangivamycin and doxorubicin) are included as comparators.
Publication Title
ARC (NSC 188491) has identical activity to Sangivamycin (NSC 65346) including inhibition of both P-TEFb and PKC.

Description
Purpose: The goal of this study is to compare the differential expression of transcripts in control kidneys compared to kidneys lacking the miR-17~92 cluster in nephron progenitors and their derivatives by RNA-seq to identify potential miRNA targets in the mutant kidneys. Overall design: mRNA profiles of control and mutant (=Six2-TGC; miR-17~92 flx/flx) embryonic day 16 kidneys were generated by deep sequencing, in triplicate, using Illumina HiSeq2000
Publication Title
MicroRNA-17~92 is required for nephrogenesis and renal function.
