摘要:

文题释义:

网络药理学:是一种新兴的交叉学科,结合了系统生物学、生物信息学、药理学和多组学技术,旨在从整体层面深入研究药物与生物系统之间的复杂相互作用,其核心理念是通过构建和分析生物分子网络,研究药物与疾病之间的多靶点、多途径相互作用机制,从而打破传统药物研究中“单一药物、单一靶点”的局限,为药物研发和疾病治疗提供更为全面和系统的理论支持。
细胞外囊泡:是由细胞主动分泌或被动释放的纳米级(30-1 000 nm)膜包被结构,具有脂质双分子层,内含蛋白质、核酸(DNA、RNA)和代谢物等生物活性分子。根据细胞外囊泡来源、大小和形成机制,主要分为3类:外泌体、微囊泡、凋亡小体,分别通过内体途径、细胞膜出芽和细胞凋亡形成。细胞外囊泡在细胞间通讯、免疫调节、组织修复和疾病发生中发挥重要作用。

摘要
背景:黑色素的过度生成是导致皮肤色素沉着和色斑形成的主要原因,生成过程受多种酶和细胞信号通路的调控。白芷作为一种传统中药材,其提取物在美白和抗炎方面具有一定的功效,但其细胞外囊泡在抗黑色素生成中的作用尚不清楚。
目的:探讨白芷细胞外囊泡对黑色素生成的影响及潜在机制。
方法:首先利用超速差速离心法从白芷中分离和纯化细胞外囊泡,通过透射电子显微镜和纳米流式分析仪对细胞外囊泡形态和粒径进行表征。采用网络药理学分析方法,筛选出9种白芷的活性成分,并预测活性成分与黑色素生成相关基因的相互作用。最后利用野生AB型斑马鱼动物模型,将不同浓度的白芷细胞外囊泡作用于斑马鱼,通过观察体表色素沉着变化以及测定酪氨酸酶活性,评估白芷细胞外囊泡的抗黑色素生成效果。

结果与结论:白芷细胞外囊泡呈典型的囊泡形态,粒径分布在30-150 nm。网络药理学分析发现,白芷中的多种活性成分如油酸乙酯、别欧前胡素等与黑色素生成相关基因如GSK3β、MITF等可能存在相互作用。在斑马鱼模型中,白芷细胞外囊泡处理组的体表色素沉着明显减少。此外,白芷细胞外囊泡还能显著降低斑马鱼的酪氨酸酶活性,其中1×108 particle/mL细胞外囊泡降低酪氨酸酶活性约30%。这些结果表明,白芷细胞外囊泡具有显著的抗黑色素生成功效,作用机制可能与调控黑色素生成相关基因酪氨酸酶的表达有关。因此,白芷细胞外囊泡有望作为美白化妆品的活性成分,为皮肤色素沉着问题的解决提供了新的思路和方法。

Abstract: BACKGROUND: Excessive melanin production is a primary cause of skin pigmentation and the formation of age spots. This process is intricately regulated by various enzymes and cellular signaling pathways. Angelica dahurica, a traditional Chinese medicinal herb, has long been recognized for its potential benefits in skin whitening and anti-inflammatory effects. However, the role of its extracellular vesicles in inhibiting melanogenesis remains largely unexplored.
OBJECTIVE: To investigate the effects of Angelica dahurica extracellular vesicles on melanin production and their underlying mechanisms.
METHODS: Extracellular vesicles were first isolated and purified from Angelica dahurica using ultracentrifugation. The morphology and size distribution of these vesicles were characterized using transmission electron microscopy and nanoparticle tracking analysis. Through network pharmacology analysis, we identified nine active components in Angelica dahurica and predicted their interactions with genes involved in melanogenesis. Finally, different concentrations of Angelica dahurica extracellular vesicles were applied to a wild-type AB zebrafish model to assess their anti-melanogenesis effects by observing changes in surface pigmentation and measuring tyrosinase activity. 
RESULTS AND CONCLUSION: Angelica dahurica extracellular vesicles exhibited typical vesicular morphology with a size distribution ranging from 30 to 150 nm. Network pharmacology analysis suggested that several active components in Angelica dahurica, such as ethyl linoleate and byakangelicin, may interact with melanogenesis-related genes like GSK3β and MITF. In the zebrafish model, treatment with Angelica dahurica extracellular vesicles significantly reduced surface pigmentation. Moreover, these Angelica dahurica extracellular vesicles notably decreased tyrosinase activity in zebrafish, with a reduction of approximately 30% at a concentration of 1×108 particles/mL. These findings indicate that Angelica dahurica extracellular vesicles possess significant anti-melanogenesis effects, likely through the regulation of melanogenesis-related genes and enzymes. Therefore, Angelica dahurica extracellular vesicles hold great potential as active ingredients in whitening cosmetics, offering new insights and approaches for addressing skin pigmentation issues.
