Journal Article
The role of salvianolic acid B and benzoylpaeoniflorin in enhancing angiogenesis through Nrf2/HO-1/VEGFA signaling axis in ischemic stroke recovery
2026
Overview
Angiogenesis is one of the essential protective mechanisms that promote neural repair and regeneration after ischemic stroke (IS). Salvianolic Acid B (SAB) and Benzoyl paeoniflorin (BP) are compounds extracted from the Chinese medicines
Bunge and
Andrews, respectively.
We investigated whether SAB combined with BP alleviated IS by promoting micrangium angiogenesis and determined the potential molecular mechanisms.
The impact of SAB-BP on angiogenesis after IS was investigated in middle cerebral artery occlusion (MCAO) rat model, ponatinib-induced ischemic stroke in zebrafish, and human umbilical vein endothelial cells (HUVECs). The neuroprotective effect of SAB-BP in rats was assessed using behavior tests and histopathological staining. The cerebral thrombosis assessment and angiogenesis assay were performed in the zebrafish model. Cell proliferation and angiogenesis in oxygen-glucose deprivation and reperfusion (OGD/R) HUVECs were assessed through cell viability, tube formation, migration, and invasion assays. Western blot analysis and immunofluorescence staining were used to determine the protein expression levels of Nrf2, HO-1, and VEGFA.
The findings indicated that SAB-BP significantly reduced neurological impairment following IS and promoted the formation of functional vessels in the cerebral ischemic penumbra. Furthermore, SAB-BP up-regulated the protein expression of Nrf2, HO-1, HIF-1α, and VEGFA. Intriguingly, the pro-angiogenic effect of SAB-BP markedly restrained by adding the inhibitor of Nrf2 (ML385).
Our study demonstrates that SAB-BP enhances angiogenesis following IS by modulating the Nrf2/HO-1/VEGFA signaling axis both
and
. SAB-BP could serve as a promising therapeutic agent for IS recovery.
