Description
In this study, we hypothesize that acetyl CoA carboxylase (ACC) is an important intermediate in Cystic fibrosis (CF) inflammatory signaling cascade. Here, we demonstrate that ACC inhibition mimics the cellular effects of ibuprofen promoting both redistribution of intracellular cholesterol and increased rates of microtubule reformation, while decreasing RhoA expression in CF epithelial cell models. Inhibiting ACC polymerization with citrate increases RhoA expression and decreases microtubule reformation rates in wild-type epithelial cells, suggesting pro-inflammatory signaling. Together, these findings demonstrate a novel mechanism of high-dose ibuprofen efficacy and point to a potential new therapeutic target for anti-inflammatory drugs in CF. Overall design: Compare broader impact of ACC inhibition on TOFA-treated (5-(Tetradecyloxy-2-furoic acid) CF HNE cells

Description
RNA-seq analysis of 16 B6J x B6NJ-F2 mice which are homozygous for either the wild-type B6J allele (binge-resistant; J/J) or mutant B6NJ allele (binge-prone; N/N), at rs240617401, a marker denoting a missense SNP in Cyfip2. Genotype identity is denoted as either J for binge-resistant; J/J, or N for binge-prone; N/N. Overall design: A sample size of N=8 per genotype was employed (4 females, 4 males; 69-100 days old at the time of sacrifice). Striatum punches were harvested on Day 24 immediately following the 5-min behavioral test on the EPM, stored in RNAlater for 48 h, blotted dry with a kimwipe, and transferred to -80ºC. Total RNA was isolated and shipped to the University of Chicago Genomics Core Facility for cDNA library preparation using the Illumina TruSeq Stranded mRNA LT Sample Prep Kit (50 bp single-end reads). Samples were sequenced using the Illumina HiSeq 4000 with 16 samples per lane over four lanes (technical quadruplicates). FASTQ files were quality checked via FASTQC and all samples exhibited Phred quality scores greater than 30 (i.e. less than 0.1% sequencing error). FASTQ files were used to align reads to the reference genome using TopHat (mm10; UCSC Genome Browser). Read counts per gene were quantified using the HTSeq Python package.

Description
RNA-seq analysis of 8 Cyfip2N/- and 8 Cyfip2N/N mice. Cyfip2N/- are mice contain one copy of the B6NJ missense mutation and one copy of the nonsense mutation (binge-resistant; N/-), whereas Cyfip2N/N are mice that have two mutated B6NJ allele (binge-prone; N/N), at rs240617401, a marker denoting a missense SNP in Cyfip2. Genotype identity is denoted as either J for binge-resistant; N/-, or N for binge-prone; N/N. Overall design: A sample size of N=8 per genotype was employed (4 females, 4 males; 82-84 days old at the time of sacrifice). Striatum punches were harvested on Day 24 immediately following the 5-min behavioral test on the EPM, stored in RNAlater for 48 h, blotted dry with a kimwipe, and transferred to -80ºC.

Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Dysregulation of Wnt/TCF signaling is closely associated with cancers arising from the gastrointestinal tract, inlcluding colon cancer and liver cancer. The goal of this study is to understand the transcriptional programs underlying Wnt/TCF activation in gastrointestinal cancers. We examined the transcriptional responses to TCF inhibition in cultured human colon cancer cells and liver cancer cells that are characteristic of Wnt pathway activation.

FoxA transcription factors are involved in development and tumorigenesis of the gastrointestinal tract. However, the downstream programs controlled by FoxA factors remain poorly understood. The goal of this study is to understand the transcriptional responses regulated by FoxA proteins in liver and colon cancer cells.

Description
Leishmania major infected human dendritic cells (DCs) exhibit a marked induction of IL-12 ultimately promoting a robust Th1-mediated response associated with parasite killing and protective immunity. In this study, we utilized Affymetrix Genechips to globally assess the host cell genes and pathways associated with L. major infection during early infection (2, 4, 8, and 24 hrs) in human myeloid-derived DCs. Bioinformatic analyses of the hybridized microarray chips identified 728 genes, represented by 848 unique probe sets, which, when compared to uninfected samples were observed to be significantly differentially expressed by one-way ANOVA. Altogether, the data provide a genome-wide perspective on the transcriptional influences Leishmania species exert within human DCs during early infection, and provides a platform for further investigations toward functionally characterizing candidate genes of importance to the IL-12 based immune response to infections.

Description
The ductus arteriosus (DA) is a fetal vascular shunt that is located between the main pulmonary artery and the aorta. Oxygenated fetal blood from the placenta is shunted past the uninflated fetal lungs, crosses the DA, and is then available to the peripheral organs. In utero closure of the DA is deleterious, but postnatal closure of the DA is necessary for establishment of pulmonary circulation and the transition to newborn life.

Description
Individuals with cystic fibrosis (CF) experience elevated inflammation in multiple organs, but whether this reflects an inherent feature of CF cells or is a consequence of a pro-inflammatory environment is not clear. Using CRISPR/Cas9-mediated mutagenesis of CFTR, 17 subclonal cell lines were generated from Caco-2 cells. Clonal lines with functional CFTR (CFTR+) were compared to those without (CFTR-) to directly address the role of CFTR in inflammatory gene regulation. All lines maintained CFTR mRNA production and formation of tight junctions. CFTR+ lines displayed short circuit currents in response to forskolin, while the CFTR- lines did not. Baseline expression of both cytokines was not different between the lines regardless of CFTR genotype. All lines responded to TNFa and IL1b by increasing IL6 and CXCL8 (IL8) mRNA levels, but the CFTR- lines produced more CXCL8 mRNA than the CFTR+ lines. Transcriptomes of 6 CFTR- and 6 CFTR+ lines, before and after stimulation by TNFa, were compared for differential expression as a function of CFTR genotype. While some genes appeared to be differentially expressed simply because of CFTR's absence, others required stimulation for differences to be apparent. Together, these data suggest cells respond to CFTR's absence by modulating transcriptional networks, some of which are only apparent when cells are exposed to different environmental contexts, such as inflammation. With regards to inflammation, these data suggest a model in which CFTR's absence leads to a poised, pro-inflammatory state of cells that is only revealed by stimulation. Overall design: Compare cells with intact CFTR to cells lacking CFTR for overall gene expression under basal and TNFa-stimulated conditions

Pancreatic Ductal Adenocarcinoma (PDAC) is one of the most aggressive human malignancies. In our studies, we find that the Gli transcription factors are required for Kras initiation of pancreatic tumorigenesis. In order to identify the downstream transcriptional targets of Gli in PDAC, we conducted gene expression analysis using Gli3T, a transcriptional repressor of Gli.
