Long Non-coding RNA H19 Promotes NLRP3-Mediated Pyroptosis After Subarachnoid Hemorrhage in Rats. Transl Stroke Res 2023; 14:987-1001. [PMID: 36418735 DOI: 10.1007/s12975-022-01104-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 10/11/2022] [Accepted: 11/09/2022] [Indexed: 11/25/2022]
Abstract
NLRP3 inflammasomes have been reported to be an essential mediator in the inflammatory response during early brain injury (EBI) following subarachnoid hemorrhage (SAH). Recent studies have indicated that NLRP3 inflammasome-mediated pyroptosis and long non-coding RNA (lncRNA) H19 can participate in the inflammatory response. However, the roles and functions of lncRNA H19 in NLRP3 inflammasome-mediated pyroptosis during EBI after SAH are unknown and need to be further elucidated. NLRP3 inflammasome proteins were significantly elevated in CSF of human with SAH induced EBI and presented a positive correlation with severity. In ipsilateral hemisphere cortex of rats, these NLRP3 inflammasome proteins were also increased and accompanied with upregulation of H19, and both of NLRP3 and H19 were peaked at 24 h after SAH. However, knockdown of H19 markedly decreased the expression of NLRP3 inflammasome proteins at 24 h after SAH in rats and also ameliorated EBI, showing improved neurobehavioral deficits, cerebral edema, and neuronal injury. Moreover, knocking down of H19 downregulated the expression of Gasdermin D (GSDMD) in microglia in SAH rats. Similarly, knockdown of H19 also alleviated OxyHb-induced pyroptosis and NLRP3-mediated inflammasomes activation in primary microglia. Lastly, H19 competitively sponged with rno-miR-138-5p and then upregulated NLRP3 expression in the post-SAH inflammatory response. lncRNA H19 promotes NLRP3-mediated pyroptosis by functioning as rno-miR-138-5p sponge in rats during EBI after SAH, which might provide a potential therapeutic target for post-SAH inflammation regulation.

Antifungal effect of the liposome encapsulation of the Trans- Caryophylene and its association with fluconazole. Chem Biol Interact 2023; 373:110377. [PMID: 36754224 DOI: 10.1016/j.cbi.2023.110377] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 01/25/2023] [Accepted: 01/31/2023] [Indexed: 02/08/2023]
Abstract
Trans-Caryophyllene (TC), a sesquiterpene, with proven biological activities, which in this work was tested alone, encapsulated in liposomes and associated with Fluconazole in vitro in an attempt to enhance the effect of the drug. Liposomes were characterized from vesicle size, polydispersity index, and Zeta potential, and imaging by scanning electron microscopy. Antifungal assays were performed against Candida albicans, Candida tropicalis and Candida krusei by microdilution to determine the IC50 values and the viability curve. The Minimum Fungicidal Concentration (MFC) was performed by subcultivation in solid medium and the inhibitory effect of the association of TC and Fluconazole and tests to verify morphological changes was performed in micro-cultivation chambers based on concentrations on microdilution plates. The corresponding IC50 data of the substances ranged from 34.4 to 65249 μg/mL, considerably high values compared to the control (Fluconazole). The MFC of all compounds showing fungistatic effect. The performance of the compounds on the cell viability curve was similar in all tested strains, as they showed no antifungal potential when compared to the control (FCZ), when associated with FCZ they showed no significant antifungal activity. The free and liposomal TC also managed to restrict 100% of the fungal dimorphism, in both concentrations, against C. albicans, and against C. tropicalis the isolated TC did not show a significant inhibitory effect; however, against the C. krusei strain inhibited 100% in filamentous growth in both concentrations, which is statistically relevant. The liposomes were homogeneous, with vesicles with diameters of 185.46 nm for the control and 143.8 nm for the liposomal TC, and a surface charge potential of - 42.6 mV. By scanning microscopy, the spherical shapes of the vesicles were verified.

Oral Administration of Ethanolic Extract of Shrimp Shells-Loaded Liposome Protects against Aβ-Induced Memory Impairment in Rats. Foods 2022; 11:foods11172673. [PMID: 36076858 PMCID: PMC9455250 DOI: 10.3390/foods11172673] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 08/23/2022] [Accepted: 08/30/2022] [Indexed: 11/16/2022] Open
Abstract
Alzheimer's disease is characterized by a progressive loss of memory and cognition. Accumulation of amyloid-beta (Aβ) in the brain is a well-known pathological hallmark of the disease. In this study, the ethanolic extract of white shrimp (Litopenaous vannamei) shells and the ethanolic extract-loaded liposome were tested for the neuroprotective effects on Aβ1-42-induced memory impairment in rats. The commercial astaxanthin was used as a control. Treatment with the ethanolic extract of shrimp shells (EESS) at the dose of 100 mg/kg BW showed no protective effect in Aβ-treated rats. However, treatment with an EESS-loaded liposome at the dose of 100 mg/kg BW significantly improved memory ability in Morris water maze and object recognition tests. The beneficial effect of the EESS-loaded liposome was ensured by the increase of the memory-related proteins including BDNF/TrkB and pre- and post-synaptic protein markers GAP-43 and PSD-95 as well as pErk1/2/Erk1/2 in the cortex and hippocampus. These findings indicated the neuroprotective effects of the EESS-loaded liposome on Aβ-induced memory impairment in rats. It produced beneficial effects on learning behavior probably through the function of BDNF/TrkB/pErk1/2/Erk1/2 signaling pathway and subsequently the upregulation of synaptic proteins. The present study provided evidence that the neuroprotective property of the ESSE-loaded liposome could be a promising strategy for AD protection.

Laminin as a Biomarker of Blood-Brain Barrier Disruption under Neuroinflammation: A Systematic Review. Int J Mol Sci 2022; 23:ijms23126788. [PMID: 35743229 PMCID: PMC9224176 DOI: 10.3390/ijms23126788] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 06/03/2022] [Accepted: 06/10/2022] [Indexed: 01/01/2023] Open
Abstract
Laminin, a non-collagenous glycoprotein present in the brain extracellular matrix, helps to maintain blood–brain barrier (BBB) integrity and regulation. Neuroinflammation can compromise laminin structure and function, increasing BBB permeability. The aim of this paper is to determine if neuroinflammation-induced laminin functional changes may serve as a potential biomarker of alterations in the BBB. The 38 publications included evaluated neuroinflammation, BBB disruption, and laminin, and were assessed for quality and risk of bias (protocol registered in PROSPERO; CRD42020212547). We found that laminin may be a good indicator of BBB overall structural integrity, although changes in expression are dependent on the pathologic or experimental model used. In ischemic stroke, permanent vascular damage correlates with increased laminin expression (β and γ subunits), while transient damage correlates with reduced laminin expression (α subunits). Laminin was reduced in traumatic brain injury and cerebral hemorrhage studies but increased in multiple sclerosis and status epilepticus studies. Despite these observations, there is limited knowledge about the role played by different subunits or isoforms (such as 411 or 511) of laminin in maintaining structural architecture of the BBB under neuroinflammation. Further studies may clarify this aspect and the possibility of using laminin as a biomarker in different pathologies, which have alterations in BBB function in common.

Abstract
Subarachnoid hemorrhage (SAH), a type of hemorrhagic stroke, is a neurological emergency with high morbidity and mortality. Early brain injury (EBI) after SAH is the leading cause of poor prognosis in SAH patients. TRX system is a NADPH-dependent antioxidant system which is composed of thioredoxin reductase (TRXR), thioredoxin (TRX). The pentose phosphate pathway (PPP), a pathway through which glucose can be metabolized, is a major source of NADPH. Thioredoxin 1 (TRX1) is a member of thioredoxin system mainly located in cytoplasm. Serine/threonine kinases ataxia telangiectasia mutated (ATM) is an important oxidative stress receptor, and TRX1 can regulate ATM phosphorylation and then affect the activity of PPP key enzyme glucose 6-phosphate dehydrogenase (G6PD). However, whether TRX1 is involved in the regulation of PPP pathway after subarachnoid hemorrhage remains unclear. The results showed that after SAH, the level of TRX1 and phosphor-ATM decreased while the level of TRXR1 increased. G6PD protein level remained unchanged but the activity decreased, and the NADPH contents decreased. Overexpression of TRX1 by lentivirus upregulates the level of phosphor-ATM, G6PD activity and NADPH content. TRX1 overexpression improved short-term and long-term neurobehavioral outcomes and alleviated neuronal impairment in rats. Nissl staining showed that upregulation of TRX1 reduced cortical neuron injury. Our study shows that TRX1 participates in the PPP pathway by regulating phosphorylation ATM, which is accomplished by affecting G6PD activity. TRX1 may be an important target for EBI intervention after SAH.

Enhancing S-nitrosoglutathione reductase decreases S-nitrosylation of Drp1 and reduces neuronal apoptosis in experimental subarachnoid hemorrhage both in vivo and in vitro. Brain Res Bull 2022; 183:184-200.

Abstract
Subarachnoid hemorrhage (SAH) is a hemorrhagic stroke with a high mortality and disability rate. Nitric oxide (NO) can promote blood supply through vasodilation, leading to protein S-nitrosylation. However, the function of S-nitrosylation in neurons after SAH remains unclear. Excessive NO in the pathological state is converted into S-nitrosoglutathione (GSNO) and stored in cells, which leads to high S-nitrosylation of intracellular proteins and causes nitrosative stress. S-nitrosoglutathione reductase (GSNOR) promotes GSNO degradation and protects cells from excessive S-nitrosylation. We conducted an in vivo rat carotid puncture model and an in vitro neuron hemoglobin intervention. The results showed that SAH induction increased NO, GSNO, neuron protein S-nitrosylation, and neuronal apoptosis, while decreasing the level and activity of GSNOR. GSNOR overexpression by lentivirus decreased GSNO but had little effect on NO. GSNOR overexpression also improved short- and long-term neurobehavioral outcomes in rats and alleviated nitrosative stress. Furthermore, GSNOR reduced neuronal apoptosis and played a neuroprotective role by alleviating Drp1 S-nitrosylation, reducing mitochondrial division. Thus, the regulation of GSNOR in early brain injury and neuronal denitrosylation may play an important role in neuroprotection.
