32 case / 6 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

BACKGROUND: Glucocorticoid (GC) refractoriness is a common and unpredictable phenomenon in ulcerative colitis (UC). Although it has been demonstrated that NFkB is involved in its mechanism of action (MoA), there are no conclusive studies on the molecular functions involved. The current study describes in depth the MoA related to GC failure, by integrating transcriptomic data from UC patients, and updated molecular data on UC and GC. METHODS: miRNA and mRNA expression from rectal biopsies of active UC patients, obtained before and on the 3rd day of GC treatment, were evaluated by sequencing and microarrays, respectively. The differential results obtained were integrated into the mathematical models generated by Systems Biology. RESULTS: This computational approach identified 64 proteins, among which 18 stand out, either by being associated to the MoA or by providing a major capacity to classify the patients according to GC response. The biological functions of these proteins have been linked with inflammation, machinery GC-induced transcription and angiogenesis. All the selected proteins but one —Acidic leucine-rich Nuclear Phosphoprotein 32 family member E (ANP32E) — had previously been related to UC and/or GC-induced biological actions. ANP32E has been linked to the exchange of H2A to H2A.z histone, which promotes CG receptor complex-activated transcription. Western blot and immunofluorescence assays confirmed the predictive results obtained by Systems Biology. CONCLUSIONS: A comprehensive MoA of GC refractoriness has been described, highlighting the key role of GC-induced transcription in this phenomenon. Several proteins have been identified as putative predictors of GC refractoriness.

Overall design

Intestinal tissue from individuals with or without active ulcerative colitis (AUC) was collected and, those with AUC were characterized for their capacity to response to glucocorticoids treatment. microRNAs and mRNAs profiles were studied for each sample by microRNAseq and gene expression microarray, respectively.

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

Both groups meet the minimum of 2 samples.

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

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.

Bioinformatician Review

Bioinformatician review required

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

Analysis readiness has blockers that must be resolved 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 Ulcerative colitis Disease context came from Normalization rules.
  • Likely case group Ulcerative colitis 32 samples
  • Likely control group Healthy control 6 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: Ulcerative colitis.
  • Processed data is available for downstream review.
  • External evidence: PubMed links 1 publication; 1 DOI available: PMID 30329026.
  • Publication context: ANP32E, a Protein Involved in Steroid-Refractoriness in Ulcerative Colitis, Identified by a Systems Biology Approach.. Journal of Crohn's & colitis, 2019. PMID 30329026. DOI 10.1093/ecco-jcc/jjy171.

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.
  • Microarray expression context downgraded below primary bulk RNA-seq for the default tissue ranking.
  • Small RNA, miRNA, circRNA, or extracellular-vesicle RNA context downgraded for primary mRNA tissue ranking.
  • Overall score capped because comparison suitability is weak for the selected search intent.
  • Overall score capped because microarray cohorts should be compared separately from RNA-seq cohorts.
  • Comparison suitability score is below the Phase 1 recommended threshold.
