This study aimed to explore the regulatory effect of anserine on HUVEC cell injury and thrombosis in deep venous thrombosis (DVT) rats, and to elucidate the underlying molecular mechanisms.
Non-targeted metabolomics data analyses were conducted using an ultra-performance liquid chromatography system Vanquish UHPLC and mass spectrometer to detect plasma metabolism profiles. The transcriptome sequencing and gene intervention experiments were performed to verify the regulatory effect. Further and experiments were performed. Enzyme-linked immunosorbent assay was used to detect the levels of P-selectin, E-selectin, and vWF, hematoxylin-eosin (HE) staining was performed to observe thrombotic and inflammatory cell infiltration, flow cytometry and TUNEL assays were performed to detect apoptosis, and qPCR and WB assays were conducted to determine the gene and protein expression.
Anserine alleviated HUVECs injury, reduced adhesion molecule expression, and inflammation. It decreased P-selectin, E-selectin, vWF, THBD, TFPI levels, and apoptosis while promoting NOS3, ET-1, and NO release in HUVECs. In DVT rats, anserine reduced P-selectin, E-selectin, vWF, thrombosis, cell infiltration, apoptosis, and promoted NO release. Transcriptome sequencing and gene intervention confirmed anserine's regulation of the PI3K-Akt pathway and coagulation via MYB. CARNMT1, a regulatory enzyme for anserine metabolism, increased anserine content, inhibiting coagulation, thrombosis, cell infiltration, and promoting NO release in rats.
This study confirmed anserine could alleviate DVT by improving the inflammatory response, inhibiting blood agglutination, and promoting vasodilation, providing new potential therapeutic targets, important scientific evidence for the development of DVT management, and new clues for an in-depth understanding of its molecular mechanisms.
本研究旨在探讨鹅肌肽对深静脉血栓形成(DVT)大鼠人脐静脉内皮细胞(HUVEC)损伤和血栓形成的调节作用,并阐明其潜在的分子机制。
使用超高效液相色谱系统Vanquish UHPLC和质谱仪进行非靶向代谢组学数据分析,以检测血浆代谢谱。进行转录组测序和基因干预实验以验证调节作用。进一步进行了[此处原文缺失相关具体实验内容]实验。采用酶联免疫吸附测定法检测P-选择素、E-选择素和血管性血友病因子(vWF)的水平,进行苏木精-伊红(HE)染色以观察血栓形成和炎症细胞浸润,采用流式细胞术和TUNEL测定法检测细胞凋亡,并进行qPCR和WB测定以确定基因和蛋白表达。
鹅肌肽减轻了HUVECs损伤,降低了黏附分子表达和炎症反应。它降低了HUVECs中P-选择素、E-选择素、vWF、血栓调节蛋白(THBD)、组织因子途径抑制物(TFPI)水平,并减少了细胞凋亡,同时促进了一氧化氮合酶3(NOS3)、内皮素-1(ET-1)和一氧化氮(NO)的释放。在DVT大鼠中,鹅肌肽降低了P-选择素、E-选择素、vWF水平,减轻了血栓形成、细胞浸润和细胞凋亡,并促进了NO释放。转录组测序和基因干预证实了鹅肌肽通过MYB对PI3K-Akt途径和凝血的调节作用。鹅肌肽代谢的调节酶CARNMT1增加了鹅肌肽含量,抑制了大鼠的凝血、血栓形成和细胞浸润,并促进了NO释放。
本研究证实鹅肌肽可通过改善炎症反应、抑制血液凝集和促进血管舒张来减轻DVT,为DVT治疗提供了新的潜在治疗靶点、重要的科学证据,并为深入了解其分子机制提供了新线索。
