Comparison of intestinal surface CD3- refractory celiac disease type II (RCDII) cell lines with intestinal surface CD3+ cell lines of non-RCDII patients

Whole-study status Not suitable

Selected cohort requirements

Samples meeting selected requirements: 0 cases / 0 controls

View matching samples

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

Analysis of transcriptional differences between aberrant (surface CD3-) RCDII cell lines and regular (surface CD3+) intraepithelial cell lines in order to characterize aberrant RCDII cells. All cell lines were cultured from duodenal biopsies of RCDII or non-RCDII (either celiac or non-celiac) patients.

Overall design

We compared 3 RCDII cell lines from RCDII patients P1-P3 with the following control cell lines: CD3+CD4+ T cell line from P1 and P3, CD3+CD8+ T cell line from P3 and mixed CD4/CD8+ T cell lines from non-RCDII patients. All control cells matched the phenotype of mature T cells (CD3+CD4+ and/or CD3+CD8+). Samples were randomly distributed among two BeadChips and measured in duplicates.

Metadata Quality Components

Analysis Readiness

Not ready
43% DE readiness

Contrast completeness

10/25 pts

Only one side of the contrast is present; downstream DE needs both groups.

Minimum group size

0/20 pts

Minimum group size cannot be evaluated until a complete contrast exists.

Processed data availability

20/20 pts

Processed data is marked available in the GEO index.

Sample decision clarity

3/15 pts

Unassigned or review-needed samples remain before analysis.

Blocking warnings

0/10 pts

Critical warnings must be resolved before downstream analysis.

Metadata normalization

10/10 pts

Metadata quality is high enough to support downstream handoff.

Blockers

  • No complete case/control contrast is available.
  • 20 samples are still unassigned.
  • 22 samples need manual grouping review.
  • Critical dataset warnings must be resolved.

Next Steps

  • Resolve unassigned or review-needed samples in the grouping table.
  • Resolve critical warnings before downstream analysis.

Analysis Preparation Checklist

3/6 ready

Group labels reviewed

Blocked

No complete case/control grouping exists yet.

Review the sample grouping table and assign both case and control groups.

Minimum sample count met

Blocked

At least one group has fewer than 2 samples.

Choose a larger dataset or merge only scientifically valid groups.

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

Needs review

22 review-needed samples and 20 unassigned samples remain.

Resolve ambiguous and unassigned samples before finalizing the contrast.

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.

Analysis readiness has blockers that must be resolved before DE.

Analysis preparation checklist contains blocked items.

No complete case/control or treatment/control contrast is available.

At least one comparison group has fewer than two samples.

One or more samples are unassigned and need manual grouping decisions.

One or more samples were flagged for manual review.

Critical dataset warnings are present.

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

Study design is model-system or unclear and should be reviewed before analysis.

Intent Interpretation

  • Downgrade or exclusion reason Comparison: Unclear study design. Specimen: Cell line. Comparison suitability: 0%. Derived from current-intent ranking reasons.

Ranking Facts

Supporting evidence

  • Interpreted disease metadata: Crohn's disease.
  • Processed data is available for downstream review.
  • External evidence: PubMed links 1 publication; 1 DOI available: PMID 22760007.

Cautions

  • Comparison: Unclear study design. Specimen: Cell line. Comparison suitability: 0%.
  • Downgraded for tissue search because it is a model-system experiment.
  • Downgraded for tissue search because study design or specimen source is unclear.
  • Downgraded assay: microarray cohorts are separated from the RNA-seq intent.
  • Excluded sample type flags reduce suitability.
  • Organoid or cell-line experiment downgraded for patient tissue search intent.
  • Unclear study design downgraded for patient tissue tumor-vs-normal search intent.
  • Missing or unclear metadata. Unclear study design downgraded for patient tissue tumor-vs-normal search intent.
  • Excluded model-system sample markers reduce suitability.
  • Overall score capped because comparison suitability is weak for the selected search intent.
  • Missing or unclear metadata. Comparison - Unclear study design. Specimen - Cell line. Comparison suitability: 0%.
  • Missing or unclear metadata. Downgraded for tissue search because study design or specimen source is unclear.
  • Comparison suitability score is below the Phase 1 recommended threshold.
