[PMID: 37964635 PMCID: PMC11139683] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 09/17/2023] [Accepted: 11/03/2023] [Indexed: 11/16/2023] Open
Abstract
Many types of cancer are associated with excessive angiogenesis. Anti-angiogenic treatment is an effective strategy for treating solid cancers. This study aimed to demonstrate the inhibitory effects of (E)-2-methoxy-4-(3-(4-methoxyphenyl) prop-1-en-1-yl) phenol (MMPP) in VEGFA-induced angiogenesis. The results indicated that MMPP effectively suppressed various angiogenic processes, such as cell migration, invasion, tube formation, and sprouting of new vessels in human umbilical vein endothelial cells (HUVECs) and mouse aortic ring. The inhibitory mechanism of MMPP on angiogenesis involves targeting VEGFR2. MMPP showed high binding affinity for the VEGFR2 ATP-binding domain. Additionally, MMPP improved VEGFR2 thermal stability and inhibited VEGFR2 kinase activity, suppressing the downstream VEGFR2/AKT/ERK pathway. MMPP attenuated the activation and nuclear translocation of NF-κB, and it downregulated NF-κB target genes such as VEGFA, VEGFR2, MMP2, and MMP9. Furthermore, conditioned medium from MMPP-treated breast cancer cells effectively inhibited angiogenesis in endothelial cells. These results suggested that MMPP had great promise as a novel VEGFR2 inhibitor with potent anti-angiogenic properties for cancer treatment via VEGFR2/AKT/ERK/NF-κB signaling pathway.

Jeon KB, Park HM, Kim S, Kim NY, Lee TE, Oh DK, Yoon DY. Phorbal-12-mysristate-13-acetate-induced inflammation is restored by protectin DX through PPARγ in human promonocytic U937 cells. Life Sci 2024; 336:122288. [PMID: 38007146 DOI: 10.1016/j.lfs.2023.122288] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Revised: 11/07/2023] [Accepted: 11/20/2023] [Indexed: 11/27/2023]
Abstract
AIMS Protectin DX (PDX), a specialized pro-resolving mediator, is an important pharmaceutical compound with potential antioxidant and inflammation-resolving effects. However, the fundamental mechanism by which PDX's ameliorate chronic inflammatory diseases has not yet been elucidated. This study aims to evaluate the anti-inflammatory properties and PPARγ-mediated mechanisms of PDX in phorbal-12-mysristate-13-acetate (PMA)-stimulated human promonocytic U937 cells. MAIN METHODS We confirmed the effects of PDX on expressions of pro-inflammatory cytokines, mediators, and CD14 using conventional PCR, RT-qPCR, ELISA, and flow cytometry. Using western blotting, immunofluorescence, and reactive oxygen species (ROS) determination, we observed that PDX regulated PMA-induced signaling cascades. Molecular docking analysis and a cellular thermal shift assay were conducted to verify the interaction between PDX and the proliferator-activated receptor-γ (PPARγ) ligand binding domain. Western blotting was then employed to explore the alterations in PPARγ expression levels and validate PDX as a PPARγ full agonist. KEY FINDINGS PDX attenuated protein and mRNA expression levels of interleukin-6, tumor necrosis factor-α, and cyclooxygenase-2 in PMA-treated U937 cells. PDX acts as a PPARγ agonist, exerting a modulating effect on the ROS/JNK/c-Fos signaling pathways. Furthermore, PDX reduced human monocyte differentiation antigen CD14 expression levels. SIGNIFICANCE PPARγ exhibits pro-resolving effects to regulate the excessive inflammation. These results suggest that PDX demonstrates the resolution of inflammation, indicating the potential for therapeutic targeting of chronic inflammatory diseases.

Cinnamomum verum extract inhibits NOX2/ROS and PKCδ/JNK/AP-1/NF-κB pathway-mediated inflammatory response in PMA-stimulated THP-1 monocytes. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 112:154685. [PMID: 36753827 DOI: 10.1016/j.phymed.2023.154685] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 12/08/2022] [Accepted: 01/28/2023] [Indexed: 06/18/2023]
Abstract
BACKGROUND Cinnamomum verum J. Presl (Cinnamon) is widely used in the food and pharmaceutical industries. C. verum exhibits various biological activities. However, it is unclear whether C. verum can inhibit NOX, a major source of ROS generation, and exert anti-inflammatory and antioxidant effects in PMA-stimulated THP-1 cells. PURPOSE This study investigates the anti-inflammatory and antioxidant effects of C. verum in PMA-stimulated THP-1 cells. METHODS The MeOH extract of C. verum was analyzed using UPLC-QTOF/MS. Anti-inflammatory and antioxidant effects of C. verum extract were examined by DCF-DA staining, immunofluorescence staining, RT-PCR, and immunoblotting in PMA-stimulated THP-1 cells. RESULTS C. verum and its components, cinnamic acid and coumarin, significantly attenuated the expression of IL-1β, IL-8, CCL5, and COX-2 in PMA-stimulated THP-1. C. verum decreased ROS levels via NOX2 downregulation, as well as ameliorated plasma membrane translocation of PKCδ and decreased JNK phosphorylation. Besides, C. verum suppressed the nuclear translocation of AP-1 and NF-κB, which modulates diverse pro-inflammatory genes. CONCLUSION C. verum effectively inhibits inflammation and oxidative stress during monocyte-macrophage differentiation and downregulates inflammatory mediators via NOX2/ROS and PKCδ/JNK/AP-1/NF-κB signaling.

Abstract
Rheumatoid arthritis is a chronic inflammatory autoimmune disease, causing articular and extra-articular dysfunctions among patients, and it could result in irreversible joint damages or disability if untreated. A traditional Chinese medicine formula, Huayu-Qiangshen-Tongbi (HT) formula, has been observed successful in controlling rheumatoid arthritis progression in traditional Chinese medicine clinics. In this study, we conducted a systematic analysis of the HT formula with a purpose of proposing for its potential mechanism of action using network pharmacological methods. The potential targets of the formula were collected and screened according to the topological features of their protein–protein interaction network, and we subsequently validated our prediction results through in vitro experiments. We proposed that the HT formula could interfere with the bone metabolism and the inflammatory pathways of the body. The experimental validation results indicated that HT formula could exhibit anti-inflammatory effects by regulating several signaling pathways specifically the Toll-like receptor signaling pathway, phosphoinositide-3-kinase–Akt signaling pathway, hypoxia-inducible factor 1 signaling pathway, mitogen-activated protein kinase signaling pathway and activator protein 1 signaling pathway.

Chun HW, Kim SJ, Pham TH, Bak Y, Oh J, Ryu HW, Oh SR, Hong JT, Yoon DY. Epimagnolin A inhibits IL-6 production by inhibiting p38/NF-κB and AP-1 signaling pathways in PMA-stimulated THP-1 cells. ENVIRONMENTAL TOXICOLOGY 2019; 34:796-803. [PMID: 30919561 DOI: 10.1002/tox.22746] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/18/2018] [Revised: 03/07/2019] [Accepted: 03/14/2019] [Indexed: 06/09/2023]
Abstract
Epimagnolin A is a lignan obtained from the flower buds of Magnolia fargesii, which is traditionally used in Asian medicine for treating headache and nasal congestion. A herbal compound fargesin obtained from M. fargesii, has exerted anti-inflammatory effects in human monocytic THP-1 cells in the previous study. The anti-inflammatory effects of epimagnolin A, however, have been not elucidated yet. In this study, it was demonstrated that epimagnolin A reduced phorbol-12-myristate-13-acetate (PMA)-induced IL-6 promoter activity and IL-6 production in human monocytic THP-1 cells. Furthermore, it was investigated the modulating effects of epimagnolin A on mitogen-activated protein kinase, nuclear factor-kappa B (NF-κB), and activator protein 1 (AP-1) activities. Phosphorylation of p38 and nuclear translocation of p50 and c-Jun were down-regulated by epimagnolin A in the PMA-stimulated THP-1 cell. The results revealed that epimagnolin A attenuated the binding affinity of NF-κB and AP-1 transcription factors to IL-6 promoter and IL-6 production through p38/NF-kB and AP-1 signaling pathways in the PMA-stimulated THP-1 cells. These results suggest that epimagnolin A can be a useful drug for the treatment of inflammatory diseases.
