摘要:

文题释义:
甾醇调节元件结合蛋白:简称SREBP,是一类转录因子家族,主要通过控制内源性胆固醇、脂肪酸、磷脂和三酰甘油合成所需的一系列酶的表达来调控脂质稳态。
创面修复:创面是正常皮肤(组织)在外界致伤因子如外科手术、外力、热、电流、化学物质、低温以及机体内在因素如局部血液供应障碍等作用下所导致的损害。常伴有皮肤完整性的破坏以及一定量正常组织的丢失,同时,皮肤的正常功能受损。通过多种治疗方式使创面恢复完整性及功能性,称为创面修复。

背景:甾醇调节元件结合蛋白(sterol regulatory element binding proteins,SREBP)是一类转录因子家族,主要通过控制内源性胆固醇、脂肪酸、磷脂和三酰甘油合成所需的一系列酶的表达来调控脂质稳态。近年来研究表明SREBP可以参与创面的炎症反应、血管生成及表皮细胞生成来调控创面愈合。
目的:总结创面修复过程中SREBP的主要调控作用及其机制。
方法:用计算机对PubMed、Web of Science、Cochrane library等英文数据库及中国知网、维普中文科技期刊全文数据库、万方医学网、中国生物医学文献数据库等中文数据库进行检索,检索范围从各数据库建库至2021-08-31发表的文献,英文检索词为“Sterol regulatory element binding proteins,Wound,Inflammation,Angiogenesis,Epidermis ”,中文检索词为“甾醇调节元件结合蛋白,创面,炎症,血管,表皮”。根据纳入和排除标准最终纳入48篇文献进行结果分析。
结果与结论:①总结了SREBP转录因子通过调节炎症、促进血管新生、再上皮化等方面促进创面愈合;②列举了调控SREBP转录因子活性的一些方法;③SREBP不仅能调控人体脂质的稳态,还能在创面修复过程中的炎症反应、血管生成、再上皮化有一定的调控作用,为创面修复提供了新的研究方向;④目前SREBP在创面修复的相关临床试验研究较少,其具体的安全性和疗效仍不能完全保证。

Abstract: BACKGROUND: Sterol regulatory element binding proteins (SREBPs) are a family of transcription factors that regulate lipid homeostasis by controlling the expression of a series of enzymes required for the synthesis of endogenous cholesterol, fatty acids, phospholipids, and triglycerides. Recent studies have shown that SREBPs can regulate wound healing through the involvement in wound inflammation, angiogenesis, and epidermal cell formation. 
OBJECTIVE: To summarize the main mechanism and application of SREBPs in wound repair.  
METHODS: English databases, including PubMed, Web of Science, and Cochrane Library, and Chinese databases, including CNKI, VIP, WanFang, and China Biomedical Literature Database, were searched for relevant literature published from database inception to August 31, 2021. The search terms were “sterol regulatory element binding proteins, wound, inflammation, angiogenesis, epidermis” in Chinese and English.  According to the inclusion and exclusion criteria, 48 documents were included for result analysis.  
RESULTS AND CONCLUSION: SREBP transcription factors can promote wound healing by regulating inflammation, promoting angiogenesis, and reepithelialization. In this review, we list some methods to regulate the activity of SREBP transcription factors. SREBP can regulate human lipid homeostasis, inflammatory responses, angiogenesis, and reepithelialization during wound repair, providing a new research direction for wound repair. To date, there are few clinical trials on the application of SREBP in wound repair, and the specific safety and efficacy of SREBP cannot be fully guaranteed.  

Key words: SREBP, inflammatory response, angiogenesis, reepithelialization, wound repair, review
