Integrative transcriptomic and single-cell analysis identifies anoikis-related molecular signatures in vascular calcification.
Article in Renal failure, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundVascular calcification (VC) is a life-threatening complication of chronic kidney disease (CKD) driven by vascular smooth muscle cell (VSMC) osteogenic transdifferentiation. Anoikis, a form of adhesion-dependent apoptosis, is involved in cardiovascular remodeling, yet its regulatory role in CKD-associated VC remains unexplored.
methodsWe performed an integrative transcriptomic and single‑cell analysis using a human
resultsWe identified 48 differentially expressed anoikis‑related genes, with the signal derived mainly from human VSMCs rather than cross‑species conservation. The cell adhesion molecule pathway was significantly dysregulated. Seven hub genes were identified: BDNF, CRYAB, CYP1B1, DAPK1, HAS2, PDGFRB, and PLAU. The seven‑gene model achieved an AUC of 0.811 in the independent validation cohort. Single‑cell analysis revealed cell‑type‑specific expression patterns, with the highest anoikis module scores in osteoblast‑like cells and macrophages.
conclusionsThis study identifies novel anoikis‑related molecular signatures associated with VC. These genes are involved in cell adhesion, VSMC homeostasis, chaperone‑mediated cytoprotection, and matrix remodeling. Our exploratory findings provide new insights into VC pathogenesis and require further functional and clinical validation in CKD‑specific cohorts.
