5-HMF inhibits glucocorticoid-induced osteoporosis through the VEGFR2/PI3K/AKT pathway.
Article in Scientific reports, 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
Chronic administration of glucocorticoids are being linked to an increased risk of osteoporosis. 5-Hydroxymethylfurfural (5-HMF) is a natural compound that possesses various biological activities, including osteogenic regulation. In this research, we sought to investigate the potential of 5-HMF to exert protective effects against glucocorticoid-induced osteoporosis. In cellular investigations, we deployed Western Blot (WB), Real-Time Quantitative real-time PCR (qRT-PCR), Alkaline phosphatase (ALP) and Alizarin S-red (ARS) staining to scrutinize the expression of osteogenic differentiation markers within MC3T3-E1 pre-osteoblasts and BMSCs. We used dexamethasone to establish a mouse model for glucocorticoid-Induced osteoporosis and administered 5-HMF to evaluate its influence on bone density and architecture through the use of micro-CT and histological analysis. In addition, we employed network pharmacology to elucidate the potential pathways and targets of 5-HMF. Finally, we explored the effect of AKT knockout on the treatment of 5-HMF. We found that 5-HMF significantly enhanced VEGFR2 phosphorylation, reestablishing angiogenesis and activating the PI3K/AKT pathway in vitro and in vivo. 5-HMF also inhibited Dexamethasone -induced apoptosis by regulating Bax and Bcl-2 expression. MK2206, an AKT inhibitor, abrogated 5-HMF’s protective properties against GCs. These results indicate that 5-HMF counteracts the negative effects of GCs on osteoblasts and has good bone-promoting differentiation effects.
