5 case / 12 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 treatment of auto-inflammatory diseases is often limited by resistance to single cytokine blockade, primarily anti-TNF antibodies. This is a particularly important cause of treatment failure in inflammatory bowel disease (IBD). The transcription factor T-bet is a critical regulator of intestinal homeostasis and is genetically linked to mucosal inflammation by causal variation in its binding sites. However, transcription factors such as T-bet are difficult to target therapeutically. Using CDK9 inhibitors, we show that modulation of P-TEFb (cyclinT1/CDK9), a transcriptional elongation factor downstream of T-bet, potently represses genes responsible for pro-inflammatory signalling, and in particular genes regulated by T-bet. Remarkably, CDK9 inhibition targets genes that are highly expressed in anti-TNF resistant IBD and that predict non-response to anti-TNF therapy. Collectively, our findings reveal CDK9 as a potential target in anti-TNF resistant IBD, which has the potential for rapid translation to the clinic.

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.

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

  • Disease context Crohn's disease, inflammatory bowel disease, ulcerative colitis Disease context came from Normalization rules.
  • Likely case group Treated 5 samples
  • Likely control group Untreated 12 samples

Intent Interpretation

  • Downgrade or exclusion reason Downgraded for tissue search because it is a treatment/control experiment. Derived from current-intent ranking reasons.

Ranking Facts

Supporting evidence

  • Comparison: Treatment vs control. Specimen: Tissue. Comparison suitability: 0%.
  • Prioritized assay: bulk RNA-seq is the active assay expectation.
  • Interpreted disease metadata: Crohn's disease, Inflammatory bowel disease, Ulcerative colitis.
  • Processed data is available for downstream review.
  • External evidence: PubMed links 1 publication; 1 DOI available: PMID 35660024.
  • Publication context: Cyclin-dependent Kinase 9 as a Potential Target for Anti-TNF-resistant Inflammatory Bowel Disease.. Cellular and molecular gastroenterology and hepatology, 2022. PMID 35660024. DOI 10.1016/j.jcmgh.2022.05.011.

Cautions

  • Downgraded for tissue search because it is a treatment/control experiment.
  • Treatment/control experiment downgraded because this ranking targets tumor-vs-normal tissue comparisons.
  • Overall score capped because comparison suitability is weak for the selected search intent.
  • Comparison suitability score is below the Phase 1 recommended threshold.
