PI3K pathway activity in the normal airway of smokers with lung cancer, and in smokers with airway dysplasia

Cytologically normal airway epithelial samples were collected during bronchoscopy of current and former smokers. Subjects enrolled in this study were either under suspicion of having lung cancer, had dysplasia in their airway, or were a healthy current, former or never smoker. We supplemented existing GEO series (GSE4115 and GSE7895) with the samples in this study to explore PI3K pathway activity in the these cohorts.

Provenance — who produced it, who reused it

Linked to 2 papers in the literature. Roles are inferred factual signals (who deposited the data vs who reused it), with counts — never a judgement about any author.

Standardized, field-standard QC computed by touching the data — every metric states how it was obtained

No quantitative QC rubric exists for this data type yet, so it is deliberately left unscored — this is an honest "not applicable", not a poor rating.

measured = computed from the data · extrapolated/reported = derived or from the repository · dq-1.0 · provisional — verify independently

Scientific quality

Based on hands-on reproduction of the papers that use this dataset. A reproducible paper that stands on this data is positive evidence; a flagged one is a prompt to look closer — never a verdict on the dataset itself without the evidence.
