Morin, a matrix metalloproteinase 9 inhibitor, attenuates endothelial-to-mesenchymal transition in atherosclerosis by downregulating Notch-1 signaling.
Objective: Atherosclerotic cardiovascular disease poses a significant health challenge globally. Recent findings highlight the pivotal role of the endothelial-to-mesenchymal transition (EndMT) in atherosclerosis. Morin is a bioflavonoid mainly extracted from white mulberry, a traditional Chinese herbal medicine with anti-inflammatory and antioxidant properties. This study examines whether morin can alleviate atherosclerosis by suppressing EndMT and seeks to elucidate the underlying mechanism.
Methods: We induced an in vitro EndMT model in human umbilical vein endothelial cells (HUVECs) by stimulating the cells with transforming growth factor-β1 (TGF-β1) (10 ng/mL) for 48 h. The in vivo experiments were performed in an atherosclerosis model using apolipoprotein E (ApoE)-/- mice fed with a high-fat diet (HFD). Mice in the intervention group were given morin (50 mg/kg) orally for 4 weeks. Molecular docking and microscale thermophoresis were assayed to understand the interactions between morin and matrix metalloproteinase-9 (MMP-9).
Results: Morin inhibited the expression of EndMT markers in a dose-dependent manner in TGF-β1-treated HUVECs. Administering 50 μmol/L morin suppressed the upregulation of MMP-9 and Notch-1 signaling in TGF-β1-induced EndMT. Moreover, the overexpression of MMP-9 activated Notch-1 signaling, thereby reversing morin's inhibitory effect on EndMT. In the HFD-induced atherosclerotic ApoE-/- mice, morin notably reduced aortic intimal hyperplasia and plaque formation by suppressing EndMT. Furthermore, morin demonstrated a strong binding affinity for MMP-9.
Conclusion: Morin acts as an MMP-9 inhibitor to disrupt EndMT in atherosclerosis by limiting the activation of Notch-1 signaling. This study underscores morin's potential utility in the development of anti-atherosclerotic medication. Please cite this article as: He Y, Qin XX, Liu MW, Sun W.

期刊介绍：
The predecessor of JIM is the Journal of Chinese Integrative Medicine (Zhong Xi Yi Jie He Xue Bao). With this new, English-language publication, we are committed to make JIM an international platform for publishing high-quality papers on complementary and alternative medicine (CAM) and an open forum in which the different professions and international scholarly communities can exchange views, share research and their clinical experience, discuss CAM education, and confer about issues and problems in our various disciplines and in CAM as a whole in order to promote integrative medicine.
JIM is indexed/abstracted in: MEDLINE/PubMed, ScienceDirect, Emerging Sources Citation Index (ESCI), Scopus, Embase, Chemical Abstracts (CA), CAB Abstracts, EBSCO, WPRIM, JST China, Chinese Science Citation Database (CSCD), and China National Knowledge Infrastructure (CNKI).
JIM Editorial Office uses ThomsonReuters ScholarOne Manuscripts as submitting and review system (submission link: http://mc03.manuscriptcentral.com/jcim-en).
JIM is published bimonthly. Manuscripts submitted to JIM should be written in English. Article types include but are not limited to randomized controlled and pragmatic trials, translational and patient-centered effectiveness outcome studies, case series and reports, clinical trial protocols, preclinical and basic science studies, systematic reviews and meta-analyses, papers on methodology and CAM history or education, conference proceedings, editorials, commentaries, short communications, book reviews, and letters to the editor.
Our purpose is to publish a prestigious international journal for studies in integrative medicine. To achieve this aim, we seek to publish high-quality papers on any aspects of integrative medicine, such as acupuncture and traditional Chinese medicine, Ayurveda medicine, herbal medicine, homeopathy, nutrition, chiropractic, mind-body medicine, taichi, qigong, meditation, and any other modalities of CAM; our commitment to international scope ensures that research and progress from all regions of the world are widely covered. These ensure that articles published in JIM have the maximum exposure to the international scholarly community.
JIM can help its authors let their papers reach the widest possible range of readers, and let all those who share an interest in their research field be concerned with their study.
