摘　　要：背景:细胞外基质是一个复杂的网络结构,不仅为组织构建提供了物理支撑,还在细胞的生存、增殖、分化、死亡等过程中发挥着重要调控作用。细胞外基质生物化学和生物力学性质的异常改变会显著影响肿瘤细胞的增殖、迁移、免疫逃逸及治疗抵抗等行为。硬度是细胞外基质的重要力学特性,基质硬度的异常与肿瘤进展紧密相关。目的:通过梳理近年来关于细胞外基质硬化的机制、高硬度基质对肿瘤进展的影响以及降低基质硬度治疗癌症等方面的最新研究进展,深化对细胞外基质力学特性的理解,提升对肿瘤进展复杂机制的认识,为肿瘤治疗提供新的思路和方向。方法:以“细胞外基质功能,细胞外基质硬度,胶原蛋白沉积交联,细胞外基质僵硬治疗,免疫治疗”为中文检索词,以“extracellular matrix function,extracellular matrix stiffness,collagen deposition cross-linking,extracellular matrix stiffness therapy,immunotherapy”为英文检索词,检索中国知网、PubMed数据库、万方数据库2016年1月至2024年6月发表的相关文献,最终纳入80篇文章进行综述。结果与结论:①细胞外基质中胶原蛋白和弹性蛋白的沉积和过度交联导致基质重塑,进而增加基质硬度,这种硬化激活了cyclin-D1、Rho/ROCK、p-PXN-Rac1-YAP、STAT3/p-STAT3等促癌信号通路,促进了癌细胞的增殖、转移、肿瘤微血管生成及免疫逃逸等恶性行为,加速了肿瘤的进展;②减少基质蛋白的沉积和交联可以降低基质硬度,不仅可以抑制多种促癌信号通路的活化,还能够增强药物在肿瘤部位的渗透和递送,是癌症治疗的新策略;③目前,基于基质降解以降低肿瘤硬度的药物正在研发中,少数药物已进入临床试验阶段,有望为肿瘤治疗提供新的有力武器。BACKGROUND:The extracellular matrix is a complex network structure,which not only builds physical support for tissue cells,but also plays an important regulatory role in cell survival,proliferation,and death.Abnormal changes in the biochemical and biomechanical properties of the extracellular matrix can significantly affect the proliferation,migration,immune evasion,and treatment resistance of tumor cells.Stiffness is an important mechanical property of the extracellular matrix,and abnormalities in matrix stiffness are closely related to tumor progression.OBJECTIVE:By reviewing the mechanism of extracellular matrix sclerosis,the impact of high stiffness matrix on tumor progression,and the latest research progress in the treatment of cancer based on reducing matrix stiffness,to deeply understand the mechanical properties of the extracellular matrix,improve the understanding of the complex mechanism of tumor progression,and provide new ideas and directions for tumor treatment.METHODS:“Extracellular matrix function,extracellular matrix stiffness,collagen deposition cross-linking,extracellular matrix stiffness therapy,immunotherapy”were used as the search terms in Chinese and English.Relevant literature published from January 2016 to June 2024 was searched in CNKI,PubMed,and WanFang databases,and 80 articles were finally included for review.RESULTS AND CONCLUSION:(1)Deposition and excessive cross-linking of collagen and elastin in the extracellular matrix leads to matrix remodeling,which in turn increases matrix stiffness.This sclerosis activates pro-cancer signaling pathways such as cyclin-D1,Rho/ROCK,p-PXN-Rac1-YAP,and STAT3/p-STAT3,promotes malignant behaviors such as cancer cell proliferation,metastasis,tumor microangiogenesis and immune escape,and accelerates tumor progression.(2)Reducing the deposition and cross-linking of matrix proteins can reduce matrix stiffness,which cannot only inhibit the activation of multiple cancer-promoting signaling pathways,but also enhance the penetration and delivery of drugs
