However, the exact mechanisms involved in neuroprotection against transient global cerebral ischemia (tGCI) remain to be elucidated. Herein, we aim at closing the gap in understanding on whether rhodiola sacra reduces neuronal death in hippocampal CA1 and at demonstrating how rhodiola sacra offers neuroprotection after tGCI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The results show that rhodiola sacra (2.4\u2009g\/kg\/d by feeding) pretreatment or\/and postreatment significantly alleviated neuronal injury, inhibited glial activation, and improved cognitive function in male rats subjected to tGCI. The neuroprotection of prophylaxis with rhodiola sacra is equivalent to that of therapeutics. The binding mode of adenosine monophosphate-activated protein kinase (AMPK) \u03b12-subunit with rhodiola sacra was predicted by molecular docking. Further, rhodiola sacra upregulates phosphorylated AMPK and promotes nuclear translocation of nuclear factor erythroid 2 related factor 2 (Nrf2). In addition, rhodiola sacra increases heme oxygenase-1 (HO-1) expression and activity and reduces malondialdehyde (MDA) content in CA1 after tGCI. However, the neuroprotection of rhodiola sacra is abolished by Nrf2 knockdown with small interfering RNA (siRNA) after tGCI. Similarly, the inhibition of AMPK with Compound C or siRNA against AMPK \u03b12 aggravates neuronal death after tGCI through decreasing nuclear Nrf2 and the expression and activity of HO-1, and by increasing the release of MDA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Innovation and Conclusion:<\/jats:title>\n                    <jats:p>\n                      For the first time, this study demonstrates that as a prophylactic or therapeutic agent rhodiola sacra prevents oxidant stress, protects neurons, and improves cognitive function through activating the AMPK\/Nrf2 pathway in tGCI rats.\n                      <jats:italic toggle=\"yes\">Antioxid.
