Abstract
BackgroundIschemic stroke (IS) is the most prevalent type of cerebrovascular disease. Taohong Siwu Decoction (THSWD) has been demonstrated to have neuroprotective benefits during Cerebral Ischemia-Reperfusion Injury (CIRI). Whether THSWD mitigates CIRI by modulating the circDnajc1/miR-27a-5p/C1qc signaling axis is not known. ObjectiveExamine how THSWD provides neuroprotective benefits in reducing the damage wrought by IS. MethodsWe employed middle cerebral artery occlusion/reperfusion (MCAO/R) rat model and oxygen glucose deprivation/re-oxygenation (OGD/R) in vitro model. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR), Western blot (WB), and immunofluorescence analyses (IF) were utilized to detect microglial activation markers TMEM119, CD11b, and Iba1, inflammatory mediators CCL2, CCL6, IL1, IL6, IL10, and TNF-α, as well as circDnajc1, miR-27a-5p, C1qc, C3, and C5aR. ConclusionOur data suggest that THSWD can mitigate inflammatory response, inhibit microglial activation and neuron apoptosis, and exert neuroprotective effects by regulating the circDnajc1/miR-27a-5p/C1qc signaling axis.
