Phellodendron amurense Rupr. Polysaccharides protects against diabetic nephropathy via alteration of PI3K/GSK-3β/Nrf2/TGF-β/Smad signaling pathway and gut microbiota.
Article in Natural products and bioprospecting, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
In this study, a diabetic nephropathy (DN) rat model was established using 2% Streptozocin (STZ) solution, and an in vitro DN model was constructed by stimulating HK-2 cells with 30 mM glucose to investigate the mechanism of Phellodendron amurense Rupr. Polysaccharides (PAP) in ameliorating DN. Results demonstrated that PAP, a neutral homogeneous polysaccharide with molecular weight of 1.98 × 105 Da composed of Rha, GalA, Gal, and D-Xyl, exerted renal protective effects through multiple pathways. It enhanced renal antioxidant capacity and alleviated oxidative damage in DN by upregulating PI3K/AKT pathway-related protein expression. Simultaneously, PAP activated the TGF-β/Smad pathway via Nrf2 to mitigate renal fibrosis symptoms in DN, while inhibiting cellular apoptosis. Furthermore, PAP suppressed renal inflammation through gut microbiota reduction, thereby protecting against renal injury in DN rats. This study reveals that PAP alleviates DN symptoms by modulating gut microbiota, enhancing antioxidant and anti-fibrotic capacities, and inhibiting apoptotic pathways, comprehensively elucidating its multifaceted therapeutic mechanisms against DN.
