Fibrostenotic phenotype of fibroblasts in Crohn's disease is dependent on tissue stiffness and reversed by LOX inhibition

Whole-study status Not suitable

Selected cohort requirements

Samples meeting selected requirements: 0 cases / 0 controls

View matching samples

16 case / 8 control samples elsewhere in the study have incomplete or conflicting evidence; they are not included above

Patient pairs verified in indexed sample metadata: 0

A case/control comparison meeting these requirements is not confirmed.

Counts describe samples, not independent patients. Pair verification uses explicit subject identifiers in indexed sample metadata. Zero verified pairs does not establish that the study is unpaired; reported matched-normal design alone is insufficient.

Summary

The results of this study indicate that stenotic fibroblasts exhibit an aberrant response to tissue stiffness with reduced MMP activity, leading to a perpetuous vicious circle of ever more fibrosis formation. Altering the microenvironment by LOX inhibition increases MMP activity and decreases ECM contraction, resulting in a potential anti-fibrotic agent for Crohn’s disease.

Overall design

Total RNA of human intestinal fibroblasts from 8 individual Crohn's disease patients. From every patient we used paired normal, inflamed and stenotic mucosa to isolate fibroblasts.

Ready after review
97% DE readiness

Contrast completeness

25/25 pts

Both case and control groups are present in the proposed grouping.

Minimum group size

20/20 pts

Each contrast group has at least 2 samples.

Processed data is marked available in the GEO index.

Sample decision clarity

15/15 pts

All samples are assigned to a case or control group.

Blocking warnings

7/10 pts

Warnings are present, but none are critical blockers.

Metadata normalization

10/10 pts

Metadata quality is high enough to support downstream handoff.

Blockers

No readiness blockers detected.

Next Steps

  • Verify the proposed sample assignments and case-versus-control comparison against the GEO metadata before using them in DESeq2 or another differential-expression tool.
  • Confirm processed count files and sample identifiers match the exported metadata.

Analysis Preparation Checklist

5/6 ready

Group labels reviewed

Needs review

Siftome proposed case and control labels, but no reviewer confirmation is stored yet.

Open the sample grouping CSV and confirm group labels before analysis.

Minimum sample count met

Ready

Both groups meet the minimum of 2 samples.

Confirm whether the cohort is large enough for the intended statistical analysis.

Processed counts available

Ready

Processed data availability is marked true in the GEO index.

Verify that downloaded processed files contain usable count or expression identifiers.

Ambiguous samples handled

Ready

No review-needed or unassigned samples are present in the proposed grouping.

Review the grouping table for biologically meaningful differences that the automated checks may not detect.

Exclusion decisions recorded

Ready

No hard-excluded samples were detected by the current rules.

Record any manual exclusions in the downstream analysis notes.

Source traceability preserved

Ready

The dataset and sample accessions can be traced back to GEO.

Keep GEO accessions with exported metadata.

Bioinformatician Review

Bioinformatician review required

Ask a bioinformatician to review grouping, count availability, exclusions, and design before DE.

Assay context may require expert handling before DESeq2-style analysis.

Why This Is Ranked Here

Tumor vs normal
Not suitable Dataset does not meet the current suitability threshold.

Applied Review Decisions

No active review decisions affect this ranking.

Derived Classifications

  • Assay differs from search intent Microarray Search intent expects bulk RNA-seq. Assay came from Normalization rules.
  • Disease context Crohn's disease, fibrosis Disease context came from Normalization rules.
  • Likely case group Crohn's disease 16 samples
  • Likely control group Healthy control 8 samples

Intent Interpretation

  • Downgrade or exclusion reason Downgraded assay: microarray cohorts are separated from the RNA-seq intent. Derived from current-intent ranking reasons.

Ranking Facts

Supporting evidence

  • Comparison: Disease/model vs control. Specimen: Tissue. Comparison suitability: 0%.
  • Interpreted disease metadata: Crohn's disease, Fibrosis.
  • Processed data is available for downstream review.
  • External evidence: PubMed links 1 publication; 1 DOI available: PMID 29672662.
  • Publication context: Fibrostenotic Phenotype of Myofibroblasts in Crohn's Disease is Dependent on Tissue Stiffness and Reversed by LOX Inhibition.. Journal of Crohn's & colitis, 2018. PMID 29672662. DOI 10.1093/ecco-jcc/jjy036.

Cautions

  • Downgraded assay: microarray cohorts are separated from the RNA-seq intent.
  • Disease/control design without a tumor/normal comparison is outside tumor/normal triage.
  • Overall score capped because comparison suitability is weak for the selected search intent.
  • Comparison suitability score is below the Phase 1 recommended threshold.
