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.

J Microbiol Biotechnol 2024; 34:240-248.

Abstract
In cancer treatment, multi-target approach has paid attention to a reasonable strategy for the potential agents. We investigated whether (E)-2-methoxy-4-(3-(4-methoxyphenyl) prop-1-en-1-yl) phenol (MMPP) could exert an anticancer effect by dual-regulating VEGFR2 and PPARγ. MMPP showed modulating effects in TNBC type (MDA-MB-231 and MDA-MB-468) and luminal A type (MCF7) breast cancer cell lines. MMPP enhanced PPARγ transcriptional activity and inhibited VEGFR2 phosphorylation. MMPP-induced signaling by VEGFR2 and PPARγ ultimately triggered the downregulation of AKT activity. MMPP exhibited anticancer effects, as evidenced by growth inhibition, inducement of apoptosis, and suppression of migration and invasion. At the molecular level, MMPP activated pro-apoptotic proteins (caspase3, caspase8, caspase9, and bax), while inhibiting the anti-apoptotic proteins (bcl2). Additionally, MMPP inhibited the mRNA expressions of EMT-promoting transcription factors. Therefore, our findings showed molecular mechanisms of MMPP by regulating VEGFR2 and PPARγ, and suggested that MMPP has potential to treat breast cancer.

Abstract
Long noncoding RNA (lncRNA) has been shown to participate in adipogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs). In this study, we aimed to investigate the role of lncRNA-LOC646762 in adipogenic differentiation of BMSCs. Transcriptome sequencing revealed a positive correlation between LOC646762 transcription and expression of adipogenic marker genes in adipogenic differentiation. Moreover, LOC646762 overexpression did not negatively impact the cell proliferation of BMSCs. Besides, LOC646762 plays a crucial role in adipogenic differentiation, as evidenced by its positive correlation with adipogenic marker gene expression. Its possible interaction with its proposed target C/EBPβ suggests its involvement in essential pathways governing adipogenesis. Collectively, our study outcomes provide valuable insights into the molecular mechanisms underlying the adipogenic differentiation of BMSCs and lay a strong foundation for further research in regenerative medicine.

Abstract
Obesity is a major risk factor for a variety of diseases and contributes to chronic inflammation. Resveratrol is a naturally occurring antioxidant that can reduce adipogenesis. In this study, the antiadipogenic and anti-inflammatory activities of resveratrol-enriched rice were investigated in 3T3-L1 adipocyte cells. Cotreatment of dexamethasone and isobutylmethylxanthin upregulated adipogenic transcription factors and signaling pathways. Subsequent treatment of adipocytes with rice seed extracts suppressed the differentiation of 3T3-L1 by downregulating adipogenic transcription factors (peroxisome proliferator-activated receptor γ and CCAAT/enhancer-binding protein α) and signaling pathways (extracellular signal-regulated kinase 1/2 and protein kinase B Akt), this was especially observed in cells treated with germinated resveratrol-enriched rice seed extract (DJ526_5). DJ526_5 treatment also markedly reduced lipid accumulation in the cells and expression of adipogenic genes. Lipopolysaccharide (LPS)-induced inflammatory cytokines (prostaglandin-endoperoxide synthase 2 (COX-2), tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6) decreased in cells treated with DJ526_5. Collectively, DJ526_5 exerts antiadipogenic effects by suppressing the expression of adipogenesis transcription factors. Moreover, DJ526_5 ameliorates anti-inflammatory effects in 3T3-L1 adipocytes by inhibiting the activation of phosphorylation NF-κB p65 and ERK ½ (MAPK). These results highlight the potential of resveratrol-enriched rice as an alternative obesity-reducing and anti-inflammatory agent.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 112:154685.

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.

Pharmaceuticals (Basel) 2023; 16:ph16040480. [PMID: 37111237 PMCID: PMC10146917 DOI: 10.3390/ph16040480] [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: 02/28/2023] [Revised: 03/14/2023] [Accepted: 03/21/2023] [Indexed: 04/29/2023] Open
Abstract
(E)-2-methoxy-4-[3-(4-methoxyphenyl) prop-1-en-1-yl] phenol (MMPP), a novel synthetic analog of (E)-2,4-bis(p-hydroxyphenyl)-2-butenal (BHPB), exerts anti-inflammatory and anticancer effects by downregulating the STAT3 pathway. It has also been recently reported that MMPP can act as a PPAR agonist which enhances glucose uptake and increases insulin sensitivity. However, it has not yet been elucidated whether MMPP can act as an antagonist of MD2 and inhibit MD2-dependent pathways. In this study, we evaluated the underlying modulatory effect of MMPP on inflammatory responses in LPS-stimulated THP-1 monocytes. MMPP inhibited the LPS-induced expression of inflammatory cytokines, such as TNF-α, IL-1β, and IL-6, as well as the inflammatory mediator COX-2. MMPP also alleviated the IKKαβ/IκBα and JNK pathways and the nuclear translocation of NF-κB p50 and c-Jun in LPS-stimulated THP-1 monocytes. In addition, the molecular docking analyses and in vitro binding assay revealed that MMPP can directly bind to CD14 and MD2, which are expressed in the plasma membrane, to recognize LPS first. Collectively, MMPP was directly bound to CD14 and MD2 and inhibited the activation of the NF-κB and JNK/AP-1 pathways, which then exerted anti-inflammatory activity. Accordingly, MMPP may be a candidate MD2 inhibitor targeting TLR4, which exerts anti-inflammatory effects.
