Tanshinone IIA Alleviates Traumatic Brain Injury by Reducing Ischemia‒Reperfusion via the miR-124-5p/FoxO1 Axis

<div>Tanshinone IIA reduces the I/R-induced inflammatory response and neuronal cell apoptosis. (a) TUNEL assay of apoptosis in rat cortical cells, scale bar = 100 <i>μ</i>m; (b–d) ELISA analysis of IL-1<i>β</i>, IL-6, and TNF-<i>α</i> levels; (e) apoptosis-related proteins were examined by western blot; (f) RT-qPCR was used to analyze the mRNA expression of apoptosis related proteins. <svg height="10.7395pt" id="M7" style="vertical-align:-0.6370001pt" version="1.1" viewbox="-0.0498162
