“…Ischemic stroke accounts for ~80% of all cases of stroke, which ranks as the second leading cause of death globally [1]. Despite the significant pharmaceutical advances that have been made in recent years, clinically effective drugs for the treatment of ischemic strokes are still lacking [2].…”

Oleanolic acid (OA), a bioactive ingredient of Panax ginseng, exhibits neuroprotective pharmacological effects. However, the protective role of OA in cerebral ischemia and involved mechanisms remain unclear. This study attempted to explore the therapeutic effects of OA both in vitro and in vivo. OA attenuated cytotoxicity and overproduction of intracellular reactive oxygen species (ROS) by regulation of glycogen synthase kinase-3β (GSK-3β)/heme oxygenase-1 (HO-1) signal in oxygen-glucose deprivation/reoxygenation (OGD/R)-exposed SH-SY5Y cells. Additionally, OA administration significantly reduced the area of cerebral infarction and the neurological scores in the rat models of cerebral ischemia with middle cerebral artery occlusion (MCAO). The OA administration group showed a higher percentage of Nissl+ and NeuN+ cells, along with lower TUNEL+ ratios in the infarct area of MCAO rats. Moreover, OA administration reduced ROS production while it suppressed the GSK-3β activation and upregulated the HO-1 expression in infarcted tissue. Our results illustrated that OA significantly counteracted cerebral ischemia-mediated injury through antioxidant effects induced by the regulation of the GSK-3β/HO-1 signaling pathway, implicating OA as a promising neuroprotective drug for the therapy of ischemic stroke.

“…The mRNA-Seq analysis showed that NRC-03 induced a significant upregulation Ppif gene that encodes CypD, a key regulator of mitochondrial mPTP in OSCC cells, which was also corroborated by RT-qPCR and Western blot analysis. mPTP is an important channel that controls material exchange and information transmission between mitochondria and cytoplasm and plays a key role in mediating apoptosis, necroptosis, and autophagy [ [84] , [85] , [86] ]. mPTP excessive opening leads to mitochondrial stress, which is characterized by impaired mitochondrial dysfunction, mitochondrial swelling, ROS generation, and release of cytochrome c , eventually leading to cell death [ [87] , [88] , [89] ].…”

“…MPTP reflects the structure and function of the mitochondria and it is located between the inner and outer membranes of the organelle (65). The lipid oxidative stress damage to the mitochondrial membrane leads to the abnormal opening of MPTP, which cannot maintain the normal potential difference of the inner membrane, while the oxidative phosphorylation on the inner membrane cannot proceed smoothly (66,67).…”

Gastrodia elata (GE) Blume has been widely used for thousands of years to treat various central and peripheral nervous disorders. P-hydroxybenzaldehyde (PHBA) is a chemical component of GE. However, its role and mechanism in transient focal cerebral ischemia remain unclear. The present study aimed to investigate the protective effect of PHBA on middle cerebral artery occlusion (MCAO) rats. A total of 56 Sprague-Dawley male rats were randomly divided into control, model, PHBA-high dose (PHBA-H) and PHBA-low dose (PHBA-L) groups. The MCAO injury model was replicated in all rats except for the control group. In the control group, only the right common carotid artery was isolated without embolization. After treatment with PHBA, the protective effects (neurological deficit score, cerebral index, weight and cerebral infarct) were analyzed. Western blotting was performed to estimate the protein levels of Bcl-2, Bax and Caspase-3. Apoptotic cells were detected using hematoxylin-eosin staining and TUNEL immunofluorescence assay. Mitochondrial oxidative stress indicators, including reactive oxygen species (ROS), malondialdehyde (MDA) and total superoxide dismutase (T-SOD), while dysfunction indicators, including mitochondrial permeability transition pore (MPTP), ATP and cytochrome C oxidase, were measured using commercial kits. The ultrastructure of mitochondria was observed under an electron microscope. Once the model was successful established, the rats in the MCAO group suffered neurological damage (P<0.001), increased cerebral index (P<0.001), decreased body weight (P<0.001) and had severe cerebral infarction (P<0.001). Moreover, the number of apoptotic cells and the levels of ROS (P<0.001) and MDA (P<0.05) in mitochondria and the protein levels of Bax (P<0.001) and cleaved caspase-3 (P<0.001) were increased. The activities of T-SOD (P<0.001) and cytochrome C oxidase (P<0.001) in the mitochondria, ATP content (P<0.05) and Bcl-2 protein level (P<0.001) decreased, MPTP was stimulated to open and mitochondrial structures were damaged (P<0.001). PHBA treatment resulted in a decrease of the neurological deficit score (PHBA-H 24 h, P<0.001; PHBA-H 6 h and PHBA-L 24 h, P<0.01; PHBA-L 6 h, P<0.05), apoptotic cell number (P<0.001), mitochondrial ROS (P<0.001) and MPTP opening (P<0.001), Bax (P<0.01, P<0.001) and cleaved caspase-3 protein expression (P<0.001) in rats. And the expression of Bcl-2 protein (P<0.001) was increased. In addition, the cerebral index (P<0.05), weight loss (P<0.05), infarction rate (P<0.01) and MDA content (P<0.001) were decrease in the PHBA-H group. The level of ATP (P<0.05) and cytochrome C oxidase (P<0.05) and T-SOD activity (P<0.05) of PHBA-H group rats increased, but no significant difference was observed in the PHBA-L group. Overall, PHBA had a protective effect on transient focal cerebral ischemia in normal rats, regulated the expression of Bcl-2, Bax and cleaved caspase-3 proteins and improved the oxidative stress and dysfunction of mitochondria.
