CNS Neurosci Ther 2024; 30:e14454. [PMID: 37697971 PMCID: PMC10916441 DOI: 10.1111/cns.14454] [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: 04/04/2023] [Revised: 05/19/2023] [Accepted: 08/16/2023] [Indexed: 09/13/2023] Open
Abstract
AIMS We investigated whether human umbilical cord mesenchymal stem cell (hUC-MSC)-derived exosomes bear therapeutic potential against lipopolysaccharide (LPS)-induced neuroinflammation. METHODS Exosomes were isolated from hUC-MSC supernatant by ultra-high-speed centrifugation and characterized by transmission electron microscopy and western blotting. Inflammatory responses were induced by LPS in BV-2 cells, primary microglial cultures, and C57BL/6J mice. H2 O2 was also used to induce inflammation and oxidative stress in BV-2 cells. The effects of hUC-MSC-derived exosomes on inflammatory cytokine expression, oxidative stress, and microglia polarization were studied by immunofluorescence and western blotting. RESULTS Treatment with hUC-MSC-derived exosomes significantly decreased the LPS- or H2 O2 -induced oxidative stress and expression of pro-inflammatory cytokines (IL-6 and TNF-α) in vitro, while promoting an anti-inflammatory (classical M2) phenotype in an LPS-treated mouse model. Mechanistically, the exosomes increased the NRF2 levels and inhibited the LPS-induced NF-κB p65 phosphorylation and NLRP3 inflammasome activation. In contrast, the reactive oxygen species scavenger NAC and NF-κB inhibitor BAY 11-7082 also inhibited the LPS-induced NLRP3 inflammasome activation and switched to the classical M2 phenotype. Treatment with the NRF2 inhibitor ML385 abolished the anti-inflammatory and anti-oxidative effects of the exosomes. CONCLUSION hUC-MSC-derived exosomes ameliorated LPS/H2 O2 -induced neuroinflammation and oxidative stress by inhibiting the microglial NRF2/NF-κB/NLRP3 signaling pathway.

Abstract
The intricate nature of Alzheimer's disease (AD) pathogenesis poses a persistent obstacle to drug development. In recent times, neuroinflammation has emerged as a crucial pathogenic mechanism of AD, and the targeting of inflammation has become a viable approach for the prevention and management of AD. The present study conducted a comprehensive review of the literature between October 2012 and October 2022, identifying a total of 96 references, encompassing 91 distinct pharmaceuticals that have been investigated for their potential impact on AD by inhibiting neuroinflammation. Research has shown that pharmaceuticals have the potential to ameliorate AD by reducing neuroinflammation mainly through regulating inflammatory signaling pathways such as NF‑κB, MAPK, NLRP3, PPARs, STAT3, CREB, PI3K/Akt, Nrf2 and their respective signaling pathways. Among them, tanshinone IIA has been extensively studied for its anti‑inflammatory effects, which have shown significant pharmacological properties and can be applied clinically. Thus, it may hold promise as an effective drug for the treatment of AD. The present review elucidated the inflammatory signaling pathways of pharmaceuticals that have been investigated for their therapeutic efficacy in AD and elucidates their underlying mechanisms. This underscores the auspicious potential of pharmaceuticals in ameliorating AD by impeding neuroinflammation.

Natural medicinal compounds target signal transduction pathways to overcome ABC drug efflux transporter-mediated multidrug resistance in cancer. Drug Resist Updat 2023; 71:101004. [PMID: 37660590 PMCID: PMC10840887 DOI: 10.1016/j.drup.2023.101004] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 08/11/2023] [Accepted: 08/19/2023] [Indexed: 09/05/2023]
Abstract
ATP-binding cassette (ABC) transporters such as ABCB1, ABCG2, and ABCC1 are the major players in drug efflux-mediated multidrug resistance (MDR), which severely affects the efficacy of chemotherapy. Several synthetic compounds block the drug transport by ABC transporters; however, they exhibit a narrow therapeutic window, and produce side effects in non-target normal tissues. Conversely, the downregulation of the expression of ABC drug transporters seems to be a promising strategy to reverse MDR in cancer cells. Several signaling pathways, such as NF-κB, STAT3, Gli, NICD, YAP/TAZ, and Nrf2 upregulate the expression of ABC drug transporters in drug-resistant cancers. Recently, natural medicinal compounds have gained importance to overcome the ABC drug-efflux pump-mediated MDR in cancer. These compounds target transcription factors and the associated signal transduction pathways, thereby downregulating the expression of ABC transporters in drug-resistant cancer cells. Several potent natural compounds have been identified as lead candidates to synergistically enhance chemotherapeutic efficacy, and a few of them are already in clinical trials. Therefore, modulation of signal transduction pathways using natural medicinal compounds for the reversal of ABC drug transporter-mediated MDR in cancer is a novel approach for improving the efficiency of the existing chemotherapeutics. In this review, we discuss the modulatory role of natural medicinal compounds on cellular signaling pathways that regulate the expression of ABC transporters in drug-resistant cancer cells.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 115:154827. [PMID: 37087792 DOI: 10.1016/j.phymed.2023.154827] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Revised: 04/07/2023] [Accepted: 04/16/2023] [Indexed: 05/03/2023]
Abstract
BACKGROUND The rising incidence of metabolic diseases due to chronic inflammation in the adipose tissue has been attributed to factors such as high fat diet (HFD). Previous studies have demonstrated that the total saponins from Panax japonicus (TSPJ) can reduce HFD-induced adipocyte inflammation, but the underlying mechanism remains unclear. In this work, we explored the molecular mechanism by which TSPJ reduces inflammation response in adipocytes. METHODS We first established C57BL/6 mouse and 3T3-L1 adipocyte models. Lentiviruses packaged with the plasmids were injected into mice through the tail vein or into adipocytes to generate the in vivo and in vitro models with miR155 knockdown and overexpression. The mice were fed with HFD to trigger inflammation and administered TSPJ (25 mg/kg∙d and 75 mg/kg∙d) by gavage. The adipocytes were treated with palmitic acid (PA) to trigger inflammation response, then treated with TSPJ (25 μg/ml and 50 μg/ml). Finally, the expression of miR155, inflammatory factors, SOCS1, and NFκB pathway-related proteins was explored. RESULTS TSPJ significantly inhibited the expression of inflammation-related genes and the miR155 expression in adipocytes both in vitro and in vivo. The dual luciferase reporter gene assay revealed that miR155 mediated the downregulation of SOCS1. TSPJ significantly inhibited and upregulated the phosphorylation of the NFκB protein and the SOCS1 proteins, respectively. CONCLUSION TSPJ inhibits miR155 to upregulate the SOCS1 expression, which subsequently inhibits the NFκB signaling pathway, thereby mitigating the inflammatory response in the adipocytes of HFD mice.

Abstract
Multiple lines of evidence indicate that the NF-κB signaling pathway plays a pivotal role in carcinogenesis; activation of NF-κB in cancer increases cell proliferation and suppresses apoptosis, both of which define tumor mass development. Inhibiting NF-κB leads to tumor suppression by blocking the IKK-α/β enzymes, thus inhibiting its translocation. Furthermore, protecting p65 from acetylation and phosphorylation inhibits NF-κB through its active site. Some small molecules are assumed to inhibit NF-κB and IκB function separately. This study took one of the previously reported NF-κB inhibitors (compound D4) as a promising lead and predicted some dual NF-κB and IκB inhibitors. We performed a virtual screening (VS) workflow on a library with 186,146 compounds with 75% similarity to compound D4 on both NF-κB and IκB proteins. A total of 186 compounds were extracted from three steps of VS 36 were common in both proteins. These compounds were subjected to the quantum polarized ligand docking to elect potent compounds with the highest binding affinity for NF-κB and IκB proteins. The MM-GBSA method calculates the lowest binding free energy for eight selected compounds. These analyses found three top-ranked compounds for each protein with suitable pharmacokinetics properties and higher in-silico inhibitory ability. In the last screening, compound CID_4969 was introduced to a molecular dynamics (MDs) simulation study as a common inhibitor for both proteins. The MDs confirmed the main interactions between the final elected compound and NF-κB/IκB proteins. Consequently, the presented computational approaches could be used for designing promising anti-cancer agents.Communicated by Ramaswamy H. Sarma.

Abstract
COVID-19 is caused by the SARS-CoV-2 virus, which enters target cells via interactions with ACE2 and TMPRSS2. Here, we show AKT serine/threonine kinase-dependent epigenetic control of ACE2 and TMPRSS2 expression by high-cannabidiol (CBD) cannabis extracts and their individual components. CBD alone and extracts #1, #5, #7, and #129 downregulated ACE2 and TMPRSS2 in lung fibroblast WI-38 cells through AKT-mediated inhibition. miR-200c-3p and let-7a-5p were two contributing miRNAs in CBD-mediated suppression of ACE2 and TMPRSS2. CBD and terpene PTWT2.2 profoundly inhibited ACE2 and TMPRSS2 expression, both individually and in combination. Extracts #1, #5, #7, and #169 suppressed COX2 expression and remarkably attenuated TNFα/IFNγ-triggered induction of proinflammatory factors IL-6 and IL-8 by AKT pathway. The most abundant molecules present in extracts #1 and #7 modulated the expression of COX2, IL-6, and IL-8 both individually and in combination. These results reveal that high-CBD cannabis extracts attenuated ACE2 and TMPRSS2 expression and the induction of inflammatory mediators COX2, IL-6, and IL-8 via the AKT pathway, highlighting their potential anti-COVID-19 features.

Abstract
Peroxisome proliferator-activated receptors (PPAR-γ, PPAR-α, and PPAR-β/δ) are ligand-dependent nuclear receptors that play a critical role in the regulation of hundreds of genes through their activation. Their expression and targeted activation play an important role in the treatment of a variety of diseases, including neurodegenerative, cardiovascular, diabetes, and cancer. In recent years, several reviews have been published describing the therapeutic potential of PPAR agonists (natural or synthetic) in the disorders listed above; however, no comprehensive report defining the role of naturally derived phytoconstituents as PPAR agonists targeting neurodegenerative diseases has been published. This review will focus on the role of phytoconstituents as PPAR agonists and the relevant preclinical studies and mechanistic insights into their neuroprotective effects. Exemplary research includes flavonoids, fatty acids, cannabinoids, curcumin, genistein, capsaicin, and piperine, all of which have been shown to be PPAR agonists either directly or indirectly. Additionally, a few studies have demonstrated the use of clinical samples in in vitro investigations. The role of the fruit fly Drosophila melanogaster as a potential model for studying neurodegenerative diseases has also been highlighted.

Abstract
OBJECTIVE Dendrobium nobile is a genuine Chinese medicine. Dendrobium nobile Lindl. alkaloids (DNLA) protects against CCl4-induced acute liver injury. This study used RNA-Seq to explore the mechanisms. METHODS Mice were pretreated with DNLA (10 and 20 mg/kg, po) for 7 days, and subsequently intoxicated with CCl4 (20 μL/kg, ip for 24 h). Liver RNA was extracted and subjected to RNA-Seq. The bioinformatics, including PCA, GO, KEGG, two-dimensional clustering, Ingenuity Pathways Analysis (IPA), and Illumina BaseSpace Correlation Engine (BSCE) were used to analyze the data. qPCR was performed on selected genes to verify RNA-Seq results. RESULTS DNLA protection against CCl4 hepatotoxicity was confirmed by histopathology. PCA revealed the distinct gene expression patterns between the different treatment groups. GO showed that CCl4 induced the activation, adhesion and proliferation of immune cells. KEGG showed CCl4 induced oxidative stress, diseases and compromised adaptive responses. CCl4 induced differentially expressed genes (DEGs) were identified by DESeq2 with Padj < 0.05 and 2D-clustered with other groups. DNLA reverted CCl4-induced DEGs in a dose-dependent manner. qPCR analysis of S100 g, Sprr1, CCL3/7, Saa2/3, IL1rn, Cox7a2 and Rad15 confirmed RNA-Seq results. IPA showed that CCl4 treatment altered some signaling and metabolic pathways, which were ameliorated or returned to normal following DNLA treatment. The CCl4-activated mitochondrial oxidative phosphorylation was illustrated as an example. IPA Upstream Regulator Analysis further revealed the activated or inhibited molecules and chemicals that are responsible for CCl4-induced DEGs, and DNLA attenuated these changes. BSCE analysis verified that CCl4-induced DEGs were highly correlated with the GEO database of CCl4 hepatotoxicity in rodents, and DNLA dose-dependently attenuated such correlation. CONCLUSION RNA-Seq revealed CCl4-induced DEGs, disruption of canonical pathways, activation or inhibition of upstream regulators, which are highly correlated with database for CCl4 hepatotoxicity. All these changes were attenuated or returned to normal by DNLA, demonstrating the mechanisms for DNLA to protect against CCl4 hepatotoxicity.

Abstract
Acute and chronic inflammation in the central nervous system plays a critical role in the development of neurodegenerative disorders. Various pro-inflammatory cytokines, chemokines, and enzymes such as TNF-α, IL1-β, IL-6, COX-1, COX-2, iNOS, IKK, and inducible nitric oxide are expressed in several signalling pathways, and mediate the neuroinflammatory process. ROS and NF-kB nuclear translocation are the two fundamental pathways involved in neuroinflammatory pathogenesis in neuronal and glial cells. In recent years several compoundswere designed to affect the neuroinflammation and suppress neurodegenerative process. Derivatives of natural products (NPs) attract the most attention of drug developers and industries due to their safety and lesser side effects in comparison with generic drugs. One of the most well-known NP is piperine, which is a yellow crystalline alkaloid extracted from black and white pepper. Recently, we developed a novel piperine derivative (((2E,4E)-5-(benzo[d][1,3]dioxol-5-yl)-N-(4-(hydroxymethyl)phenyl)penta-2,4-dienamide, D4) to enhance the specificity and efficacy of the base molecule. Next, we evaluated the potential anti-inflammatory properities of D4 in CHME3 and SVG cell-lines corresponding to human microglia and astrocytes, respectively. Our results indicated that D4 inhibited NF-kB translocation pathway, and significantly reduced transcript and protein levels of pro-inflammatory cytokines in comparison with Aspirin, as a well-known non-selective NSAID. Furthermore, in silico study showed excellent D4 bioavailability in oral administration. The results of the present study suggest a novel molecule with high anti-neuroinflammatory potency for further pre-clinical tests and pharmacological drug investigation.
