研究问题
Diabetic kidney disease develops in approximately 40% of people with diabetes and is the leading cause of chronic kidney disease and end-stage kidney disease worldwide.
方法
Three human kidney transcriptomic cohorts with DKD and control groups were analyzed: GSE142025 (bulk RNA-seq; 27 DKD expression profiles available in the deposited series and 9 controls; the source study reports 28 enrolled DKD patients) [13], GSE30529 (tubulointerstitial microarray; 10 diabetic and 12 control) [14] and GSE104954 (European Renal cDNA Bank tubulointerstitial microarray; 17 diabetic nephropathy and 21 living-donor control) [15].；The three bulk cohorts are distinct GEO series from separate primary studies and platforms (one bulk RNA-seq and two tubulointerstitial microarrays) with no shared samples; complete patient-level independence cannot be confirmed from public metadata.；This heterogeneity is deliberate: a senescence-associated signal that persists across whole-kidney RNA-seq and two tubulointerstitial microarray series, measured in different patient populations, is less likely to reflect a platform-specific or cohort-specific artefact than a signal derived from a single series.；Single-Nucleus Analysis] zUMIs dgecounts matrices (intron + exon UMI counts) from the…
核心结论
After Benjamini–Hochberg correction across the six two-sided tests, all six had BH-adjusted q values below 0.10, although only one met the prespecified conventional 0.05 threshold ( GSE30529 , Fridman set, FDR = 0.013); the strongest single effect was also in GSE30529 (rank-biserial 0.78, 95% CI 0.45–1.00).；An additional random-effects sensitivity synthesis supported this directional consistency for SenMayo (pooled rank-biserial 0.38, 95% CI 0.11–0.60; I2 = 0%) and Fridman (0.40, 95% CI 0.11–0.63; I2 = 0%). ‖ 结论：The mechanistic classes recovered are largely those with prior experimental or clinical support; the work should therefore be understood not as the discovery of new drug classes but as a calibrated computational framework that confirms disease-relevant biology and points to a small set of testable, prioritized options.
局限
The bulk cohorts also differ in tissue compartment (one whole-kidney and two tubulointerstitial) and array or sequencing platform, which may limit cross-cohort comparability.；Finally, the stricter NCSct, directional-consistency and FDR sensitivity filter did not remove broadly cytotoxic or stress-inducing perturbagens, showing that connectivity calibration alone cannot establish senescence specificity.
