Dapagliflozin regulates chondrocyte homeostasis and protects against osteoarthritis via targets AMPKα and SGLT2.
Article in Cell death discovery, 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
Osteoarthritis (OA) is a degenerative joint disease characterized by progressive cartilage degradation and a complex pathogenesis. Degenerated chondrocytes exhibit an imbalance between catabolism and anabolism, leading to cartilage matrix loss. Currently, there are no effective clinical therapies to halt or reverse this degeneration. This study investigated the therapeutic potential of Dapagliflozin (DAPA) for OA. We demonstrated that DAPA exerts protective effects on cartilage explants from patients with OA as well as in surgically induced OA models in mice. In vitro studies revealed that DAPA ameliorates OA by restoring chondrocyte metabolic homeostasis. Transcriptome sequencing showed that DAPA activated the AMP-activated protein kinase (AMPK) signaling pathway while suppressing MAPK signaling. Mechanistically, AMPKα was identified as a novel target of DAPA. DAPA alleviated excessive catabolism by targeting both AMPKα and SGLT2, while promoting anabolic processes through AMPKα activation. Furthermore, DAPA rescued impaired autophagy caused by SGLT2 upregulation in degenerated chondrocytes. Our findings demonstrated that DAPA regulates cartilage metabolism by concurrently modulating AMPKα and SGLT2, underscoring the therapeutic promise of combined AMPK activation and SGLT2 inhibition in OA treatment.
