Brain Sci 2024; 14:781. [PMID: 39199474 DOI: 10.3390/brainsci14080781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2024] [Revised: 07/11/2024] [Accepted: 07/30/2024] [Indexed: 09/01/2024] Open
Abstract
Cerebral ischemia-reperfusion injury (IRI), occurring after blood supply restoration, contributes significantly to stroke-related deaths. This study explored the combined impact and mechanisms of astragaloside IV (AS-IV), hydroxysafflor yellow A (HSYA), and their combination in mitigating IRI. Male Sprague-Dawley (SD) rats were randomized to the Sham, MCAO, MCAO+AS-IV, MCAO+HSYA, and MCAO+AS-IV+HSYA groups. Neurological deficits and cerebral infarction were examined after restoring the blood supply to the brain. Pathomorphological changes in the cerebral cortex were observed via HE staining. IL-1β and IL-18 were quantified using ELISA. The expression of NF-κB and GSDMD in the ischemic cerebrum was analyzed using immunohistochemistry. The expression levels of NLRP3, ASC, IL-1β, Caspase-1, and GSDMD in the ischemic cerebrum were evaluated using Western blot. The MCAO+AS-IV, MCAO+HSYA, and MCAO+AS-IV+HSYA groups exhibited notably better neurological function and cerebral infarction compared with the MCAO group. The combined treatment demonstrated superior brain tissue injury alleviation. Reductions in NF-κB, GSDMD positive cells, and NLRP3/ASC/IL-1β/Caspase-1/GSDMD protein expression in the ischemic brain were significantly more pronounced with the combined therapy, indicating a synergistic effect in countering cerebral IRI via the NF-κB/NLRP3/Caspase-1/GSDMD pathway inhibition of cell pyroptosis-induced injury.

Lee HL, Kim JM, Go MJ, Lee HS, Kim JH, Heo HJ. Fermented Protaetia brevitarsis Larvae Improves Neurotoxicity in Chronic Ethanol-Induced-Dementia Mice via Suppressing AKT and NF-κB Signaling Pathway. Int J Mol Sci 2024; 25:2629. [PMID: 38473876 DOI: 10.3390/ijms25052629] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 02/21/2024] [Accepted: 02/22/2024] [Indexed: 03/14/2024] Open
Abstract
This study was investigated to examine the neuroprotective effect of fermented Protaetia brevitarsis larvae (FPB) in ethanol-induced-dementia mice. Consumption of FPB by mice resulted in improved memory dysfunction in the Y-maze, passive avoidance, and Morris water maze tests. FPB significantly decreased oxidative stress by regulating levels of malondialdehyde (MDA), superoxide dismutase (SOD), and reduced glutathione (GSH) in brain tissues. In addition, FPB restored cerebral mitochondrial dysfunction by modulating levels of reactive oxygen species (ROS), mitochondrial membrane potential (MMP), and ATP. In addition, FPB enhanced the cholinergic system via the regulation of acetylcholine (ACh) content, acetylcholinesterase (AChE) activity, and expressions of AChE and choline acetyltransferase (ChAT) in brain tissues. FPB ameliorated neuronal apoptosis through modulation of the protein kinase B (AKT)/B-cell lymphoma (BCL)-2 signaling pathway. Also, FPB improved inflammation response by down-regulating the toll-like receptor (TLR)-4/nuclear factor (NF)-κB pathway. Additionally, FPB ameliorated synaptic plasticity via the increase of the expressions of synaptophysin (SYP), postsynaptic density protein (PSD)-95, and growth-associated protein (GAP)-43. Treatment with FPB also reinforced the blood-brain barrier by increasing tight junctions including zonula occludens (ZO)-1, occludin, and claudin-1. In conclusion, these results show that FPB can improve cognitive impairment via AKT/NF-κB pathways in ethanol-induced-dementia mice.

Abstract
Angelica gigas Nakai (AGN) root is a medicinal herbal widely used in traditional medicine in Korea. AGN root ethanolic extract dietary supplements are marketed in the United States for memory health and pain management. We comprehensively reviewed the anticancer, analgesic, pro-memory and other bio-activities of AGN extract and its signature phytochemicals decursin, decursinol angelate, and decursinol a decade ago in 2012 and updated their anticancer activities in 2015. In the last decade, significant progress has been made for understanding the pharmacokinetics (PK) and metabolism of these compounds in animal models and single dose human PK studies have been published by us and others. In addition to increased knowledge of the known bioactivities, new bioactivities with potential novel health benefits have been reported in animal models of cerebral ischemia/stroke, anxiety, sleep disorder, epilepsy, inflammatory bowel disease, sepsis, metabolic disorders, osteoporosis, osteoarthritis, and even male infertility. Herein, we will update PK and metabolism of pyranocoumarins, review in vivo bioactivities from animal models and human studies, and critically appraise the relevant active compounds, the cellular and molecular pharmacodynamic targets, and pertinent mechanisms of action. Knowledge gaps include whether human pyranocoumarin PK metrics are AGN dose dependent and subjected to metabolic ceiling, or metabolic adaptation after repeated use. Critical clinical translation challenges include sourcing of AGN extracts, product consistency and quality control, and AGN dose optimization for different health conditions and disease indications. Future research directions are articulated to fill knowledge gaps and address these challenges.
