Tracheoesophageal fistula characterisation

ABSTRACT: Esophageal atresia and tracheoesophageal fistula (EA/TEF) are relatively frequently occurring foregut malformations with a largely unknown etiology. EA/TEF is thought to have a strong genetic component and several genes have been proven to be involved in syndromic EA/TEF. However, it is not clear which biological processes or gene networks are disturbed. To gain more insight in the origin of the TEF, we aimed to examine and describe TEF composition using a combination of whole-genome transcription profiling and (immuno-) histochemical stainings. We hypothesized that such characterization of human TEFs provides insight in the molecular and mechanistic etiology of EA/TEF. Data analysis was carried out using BRB-array tools version 4.6.0 (October 2018) in combination with R version 3.5.1 (July 2018). For each probe set, the geometric mean of the hybridization intensities of all samples was calculated. The level of expression of each probe set was determined relative to this geometric mean and logarithmically transformed (on a base 2 scale) to ascribe equal weight to gene-expression levels with similar relative distances to the geometric mean.

Association of microRNAs with colon tumor metastases

Project description:We compared the expression of microRNAs in primary colon tumors with their paired liver metastases using the Nanostring human microRNA assays version 1 23 microRNAs were found to be differentially expressed between colon primary tumors and their paired metastases Total mRNA was extracted from flash frozen primary colon tumors and paired metastases. 18 tissues from 9 donors were used for this study. 100 ng of RNA was hybridized to Nanostring Human 0microRNA assays version 1.0. Data was normalized according to manufacterer's recommendation. This included background substraction and normalizing to the geometric mean of the highest 75 microRNAs.

Comparative genomic and transcriptomic analysis revealed genetic characteristics related to solvent formation and xylose utilization in Clostridium acetobutylicum EA 2018

Project description:Transcriptomic profiling of gene expression in EA 2018 relative to that of ATCC824 revealed several key genes related to solvent formation. For example, spo0A and adhEII have higher expression level, and most of the acid formation related genes have lower expression level in EA 2018. Cells for RNA isolation were grown on P2 medium and collected at 9 h, 13 h, 17 h, 21 h, 24 h and 30 h by centrifugation at 4M-BM-0C and 4500 x g for 10 min. Total RNA was extracted and purified by using Trizol (Invitrogen, Carlsbad, CA, USA) and RNeasy cleanup kit (Qiagen, Inc., Valencia, CA, USA) according to the manufacturerM-bM-^@M-^Ys protocol. The total RNA yield was quantified by spectrophotometric analysis (NanoDrop Technology, Cambridge, UK) and the quality was verified by gel electrophoresis. Agilent oligonucleotide microarrays technology was used for monochromic analysis, in which probes (size: 60bp; three replicates for each ORF) from the two groups were labeled by incorporation of cyanine 3 (Cy3) (Agilent Technologies, Palo Alto, CA, USA). Average linkage hierarchical clustering was performed using Cluster 3.0, and gene clusters were visualized in Treeview

Multimodal single cell analyses reveal mechanisms of perianal fistula in diverse Crohn’s disease [Multiome]

Project description:Crohn’s disease (CD) is a chronic inflammatory condition that can affect any part of the gastrointestinal tract. African ancestry (AA) populations have been substantially under-represented in genome-wide association studies (GWAS) of CD and inflammatory bowel disease (IBD), reflecting in part the lower prevalence of CD in AA compared to European ancestry (EA) populations. Importantly, CD complicated by perianal fistulae has been found to be more prevalent and severe in African-ancestry patients. Perianal fistulae arise from the distal rectal mucosa and can course to a cutaneous surface, resulting in highly morbid complications. Monoclonal antibodies against anti-TNF are the mainstay of treatment, but recurrence and secondary loss-of-response is common. In severe, uncontrolled cases, complete proctectomy is required. The intestine is unique among adult tissues in that under homeostasis, residential macrophages are continually replenished from recruited blood monocytes. In EA cohorts, we established that chronic monocyte cultures stimulated with NOD2 agonists result in aberrant myeloid-stromal differentiation stratified by risk allele carrier status. NOD2 risk alleles are not associated with perianal fistulae; African-American patients with CD do not carry them (except via recent European ancestry admixture). There is no direct association between known CD GWAS risk loci and the risk of developing perianal fistula. Here, we present direct ex-vivo, single cell multiomic analyses of colorectal tissues and perianal fistulous tracts in AA and EA cases to define mechanisms of perianal fistula development. We implicate myeloid-stromal crosstalk and define cell subtypes using single cell RNA (scRNASeq), ATAC sequencing, and chronic, unstimulated monocyte cultures. Transcription factor motifs and ATAC signals co-localized with fine-mapped GWAS loci provide insight to cell-specific and transcriptional network regulation.
