Anchesi I, Schepici G, Mazzon E. LncRNAs and CircRNAs as Strategies against Pathological Conditions Caused by a Hypoxic/Anoxic State. Biomolecules 2023; 13:1622. [PMID: 38002304 PMCID: PMC10669691 DOI: 10.3390/biom13111622] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 10/26/2023] [Accepted: 10/28/2023] [Indexed: 11/26/2023] Open
Abstract
Brain damage can be induced by oxygen deprivation. It is known that hypoxic or anoxic conditions can lead to changes in the expression levels of non-coding RNAs (ncRNAs), which, in turn, can be related to Central Nervous System (CNS) injuries. Therefore, it could be useful to investigate the involvement of non-coding RNAs (ncRNAs), as well as the underlying mechanisms which are able to modulate them in brain damage induced by hypoxic or anoxic conditions. In this review, we focused on recent research that associates these conditions with long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs). The results of this review demonstrate that the expression of both lncRNAs and circRNAs can be influenced by oxygen deprivation conditions and so they can contribute to inducing damage or providing neuroprotection by affecting specific molecular pathways. Furthermore, several experimental studies have shown that ncRNA activity can be regulated by compounds, thus also modifying their transcriptomic profile and their effects on CNS damages induced by hypoxic/anoxic events.

LINC00938 alleviates hypoxia ischemia encephalopathy induced neonatal brain injury by regulating oxidative stress and inhibiting JNK/p38 MAPK signaling pathway. Exp Neurol 2023; 367:114449. [PMID: 37257715 DOI: 10.1016/j.expneurol.2023.114449] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 05/24/2023] [Accepted: 05/24/2023] [Indexed: 06/02/2023]
Abstract
Hypoxic-ischemic encephalopathy (HIE) is an important factor leading to permanent damage of central nervous system (CNS) and even neonatal death. Long non-coding RNAs (lncRNAs) has been shown to get involved in the pathogenesis of nervous system diseases. LINC00938 is an intergenic lncRNA which is reported to be involved in neurodegenerative disease. However, the potential role of LINC00938 in nerve injury of neonatal HIE is undetermined. Here, we found that the expression of LINC00938 in the whole blood of neonates with HIE was downregulated compared with the non-HIE group. Functional study revealed that the expression of LINC00938 was significantly decreased in oxygen-glucose deprivation (OGD)-induced SH-SY5Y. Knockdown of LINC00938 induced the neural cell apoptosis by increased the protein level of Bax, Cleaved-Caspase3 and decreased the expression of Bcl-2. In addition, overexpression of LINC00938 prevented the apoptosis of SH-SY5Y from OGD injury. RNA-seq analysis showed that MAPK signaling was involved in the anti-apoptosis function of LINC00938. LINC00938 knockdown induced the activation of c-Jun-N-terminal kinase (JNK), p38 mitogen-activated protein kinase, and inhibited the activation of ERK signaling. However, LINC00938 play neuroprotective role in OGD-induced SH-SY5Y by suppression the phosphorylation of JNK and p38 MAPK rather than regulation of ERK signaling pathway. Further analyses illustrated that the cell apoptosis of neuronal cell was dependent on the elevation of reactive oxygen species (ROS) and result in mitochondria dysfunction in LINC00938 knockdown SH-SY5Y. Pretreated with ROS inhibitor N-acetylcysteine amide (NACA) dramatically suppressed LINC00938 knockdown induced oxidative stress and mitochondria dysfunction which induced cell apoptosis. In addition, NACA treatment significantly reduced the expression of p-JNK and p-p38 in OGD-induced SH-SY5Y. Furthermore, overexpression of LINC00938 displayed a notably neuroprotective effect by suppress central nervous system cell apoptosis via alleviating oxidative stress in CoCl2-induced hypoxic HIE model of zebrafish. Taken together, these results suggested that LINC00938 can act as a neuroprotective factor to inhibit oxidative stress and apoptosis of CNS under HIE conditions.

Abstract
IκBζ (encoded by NFKBIZ) is the most recently identified IkappaB family protein. As an atypical member of the IkappaB protein family, NFKBIZ has been the focus of recent studies because of its role in inflammation. Specifically, it is a key gene in the regulation of a variety of inflammatory factors in the NF-KB pathway, thereby affecting the progression of related diseases. In recent years, investigations into NFKBIZ have led to greater understanding of this gene. In this review, we summarize the induction of NFKBIZ and then elucidate its transcription, translation, molecular mechanism and physiological function. Finally, the roles played by NFKBIZ in psoriasis, cancer, kidney injury, autoimmune diseases and other diseases are described. NFKBIZ functions are universal and bidirectional, and therefore, this gene may exert a great influence on the regulation of inflammation and inflammation-related diseases.

Neuroprotective Mechanism of Icariin on Hypoxic Ischemic Brain Damage in Neonatal Mice. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:1330928. [DOI: 10.1155/2022/1330928] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 10/07/2022] [Accepted: 10/27/2022] [Indexed: 11/16/2022]
Abstract
Objective. Our previous results showed that icariin (ICA) could inhibit apoptosis and provide neuroprotection against hypoxic-ischemic brain damage (HIBD) in neonatal mice, but the specific mechanism of its neuroprotective effect remains unknown. This study aims at exploring whether ICA plays a neuroprotective role in apoptosis inhibition by regulating autophagy through the estrogen receptor α (ERα)/estrogen receptor β (ERβ) pathway in neonatal mice with HIBD. Methods. A neonatal mouse model of HIBD was constructed in vivo, and an oxygen and glucose deprivation (OGD) model in HT22 cells from the hippocampal neuronal system was constructed in vitro. The effects of ICA pretreatment on autophagy and the expression of ERα and ERβ were detected in vitro and in vivo, respectively. ICA pretreatment was also supplemented with the autophagy inhibitor 3-methyladenine (3-MA), ERα inhibitor methylpiperidino pyrazole (MPP), and ERβ inhibitor 4-(2-phenyl-5,7-bis (trifluoromethyl) pyrazolo [1,5-a] pyramidin-3-yl) phenol (PHTPP) to further detect whether ICA pretreatment can activate the ERα/ERβ pathway to promote autophagy and reduce HIBD-induced apoptosis to play a neuroprotective role against HIBD in neonatal mice. Results. ICA pretreatment significantly promoted autophagy in HIBD mice. Treatment with 3-MA significantly inhibited the increase in autophagy induced by ICA pretreatment, reversed the neuroprotective effect of ICA pretreatment, and promoted apoptosis. Moreover, ICA pretreatment significantly increased the expression levels of the ERα and ERβ proteins in HIBD newborn mice. Both MPP and PHTPP administration significantly inhibited the expression levels of the ERα and ERβ proteins activated by ICA pretreatment, reversed the neuroprotective effects of ICA pretreatment, inhibited the increase in autophagy induced by ICA pretreatment, and promoted apoptosis. Conclusion. ICA pretreatment may promote autophagy by activating the ERα and ERβ pathways, thus reducing the apoptosis induced by HIBD and exerting a neuroprotective effect on neonatal mice with HIBD.

Abstract
Purpose: To explore the neuroprotective effects of Lutongkeli (LTKL) in traumatic brain injury (TBI) and detect the related mechanism. Methods: TBI model was established with LTKL administration (2 and 4 g/kg/d, p.o.). Motor function of rats was examined by Rotarod test. Nissl staining was used to show neuron morphology. Furthermore, the disease-medicine common targets were obtained with the network pharmacology and analyzed with Kyoto Encyclopedia of Genes and Genomes. Lastly, the predicted targets were validated by real-time polymerase chain reaction. Results: After LTKL administration, neural behavior was significantly improved, and the number of spared neurons in brain was largely increased. Moreover, 68 bioactive compounds were identified, corresponding to 148 LTKL targets; 2,855 genes were closely associated with TBI, of which 87 overlapped with the LTKL targets and were considered to be therapeutically relevant. Functional enrichment analysis suggested LTKL exerted its pharmacological effects in TBI by modulating multiple pathways including apoptosis, inflammation, etc. Lastly, we found LTKL administration could increase the mRNA level of Bcl-2 and decrease the expression of Bax and caspase-3. Conclusions: This study reported the neuroprotective effect of LTKL against TBI is accompanied with anti-apoptosis mechanism, which provides a scientific explanation for the clinical application of LTKL in the treatment of TBI.

Abstract
This study aimed to decipher the effect of glycoprotein nonmetastatic melanoma protein B (GPNMB) on neonatal hypoxic-ischemic encephalopathy (NHIE) and its potential molecular mechanism. The hypoxic-ischemic (HI) model was established in 7-day-old rats, and then, Zea-Longa scores and Nissl staining were performed to measure brain damage post-HI. In addition, gene sequencing was used to detect the differential expression genes (DEGs), and then, Gene Ontology and Kyoto Encyclopedia of Genes and Genomes databases were used to determine the function of DEGs. Furthermore, an oxygen-glucose deprivation (OGD) model was developed in SY5Y cells and human fetal neurons, and then, the level of GPNMB was verified by quantitative real-time polymerase chain reaction. In addition, methyl thiazolyl tetrazolium and cell counting kit-8 assays were applied after GPNMB interference. Finally, the alternative splicing of GPNMB expression was analyzed using Splice Grapher software. The results indicated that HI induced marked neurological impairment and neuron injury in rats. Also, GPNMB was the most obviously upregulated gene in DEGs. Additionally, GPNMB was upregulated significantly in SY5Y and fetal neurons after OGD, and GPNMB-si promoted an increase in cell viability and number. Moreover, we found that the GPNMB alternative splicing type was the Alternative 3' splice site, with the alternative splicing site in 143382985:143404102. Herein, GPNMB promotes a crucial regulatory mechanism with alternative splicing for neuronal survival after NHIE.

Downregulating EVA1C exerts the potential to promote neuron growth after neonatal hypoxic-ischemic encephalopathy injury associated with alternative splicing. IBRAIN 2022; 8:481-491.

Abstract
Neonatal hypoxic-ischemic encephalopathy (NHIE) is one of the major diseases in newborns during the perinatal stage, which globally is the main reason for children's morbidity and mortality. However, the mechanism of NHIE still remains poorly clear. In this study, the 7-day-old rats were subjected to hypoxic-ischemia (HI), then brain damage was detected. Afterward, the expression of eva-1 homolog C (EVA1C) was measured in vitro by establishing the oxygen-glucose deprivation (OGD) model in SHSY5Y cells and human fetal neurons. Subsequently, the potential function and mechanism of EVA1C were explored by silencing EVA1C and alternative splicing prediction. As a result, obvious neurobehavioral impairment and brain infarction were detected through Zea-Longa score and TTC staining; meanwhile, neuron injury was tested by HE and Nissl staining post HI. Moreover, it was found that the expression of EVA1C was notably upregulated in SHSY5Y cells and human fetal neurons after OGD. In addition, cell survival and growth were increased after silencing EVA1C, which might be associated with alternative splicing. In conclusion, EVA1C interference exhibited potential in promoting neuron survival and growth, associated with exon skipping with the alternative splicing site in 34613318:34687258, which may provide the basis for the therapeutic target and mechanism research of NHIE.
