1 · What the graph read from it

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.

2 · The registry

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

aimTo explore how vacuolar protein sorting 35 (VPS35) regulates astrocytic inflammation, impairs retinal endothelial function and drives early diabetic retinopathy (DR) neurovascular lesions in diabetic mouse model.

methodsA streptozotocin (STZ)-induced C57BL/6J diabetic mouse model was established. Retinal tissues were collected from 0 to 12wk after successful induction of diabetes. Protein expression levels of VPS35, glial fibrillary acidic protein (GFAP), excitatory amino acid transporter 2 (EAAT2), leucine-rich repeat kinase 2 (LRRK2), and vascular endothelium-associated proteins were assessed by Western blotting (WB). The interaction between VPS35 and LRRK2 was verified by co-immunoprecipitation. Vascular leakage and astrocyte activation were evaluated by fundus fluorescein angiography and retinal flat-mount immunofluorescence staining. Primary astrocytes were cultured

resultsIn diabetic mice, retinal VPS35 protein expression exhibited a progressive decline beginning at 4wk post-diabetes onset, whereas GFAP protein expression increased significantly. By 8wk, marked astrocyte activation was observed, accompanied by retinal microvascular leakage and a reduction in vascular area.

conclusionDuring early DR in mice model, decreased retinal VPS35 protein expression induces astrocyte-mediated inflammatory responses and glutamate transport dysfunction. Through the interaction between VPS35 and LRRK2, paracrine inflammatory cytokines subsequently activate the NF-κB signaling pathway in vascular endothelial cells, leading to endothelial dysfunction and further driving DR-associated neurovascular injury. This study provides novel insights into the pathogenesis of DR and highlights the potential of VPS35 as a target for early intervention in DR.
