Cancer‑associated fibroblasts (CAFs) represent an important component of the stromal cell population within the tumor microenvironment (TME) and are intricately linked to tumor growth, metastasis and drug resistance. In the TME, non‑coding RNAs present in exosomes act as essential mediators of intercellular communication. Exosomal RNAs derived from cancer cells activate CAFs, which in turn regulate cancer cell proliferation, invasion and drug resistance. Conversely, exosomal RNAs derived from CAFs contribute to therapeutic resistance in cancer by modulating survival signaling pathways, epithelial‑mesenchymal transition, programmed cell death, drug transporter expression levels and immune evasion. The present review examines the role and mechanisms of exosomal RNAs in CAF‑mediated cancer therapeutic resistance and offers recommendations for future research based on the underlying mechanisms of CAF‑induced drug resistance.
癌症相关成纤维细胞(CAFs)是肿瘤微环境(TME)中基质细胞群体的重要组成部分,与肿瘤生长、转移和耐药性密切相关。在TME中,外泌体中存在的非编码RNA是细胞间通讯的重要介质。源自癌细胞的外泌体RNA激活CAFs,进而调节癌细胞的增殖、侵袭和耐药性。相反,源自CAFs的外泌体RNA通过调节生存信号通路、上皮-间质转化、程序性细胞死亡、药物转运蛋白表达水平和免疫逃避,促进癌症的治疗抵抗。本综述探讨了外泌体RNA在CAF介导的癌症治疗抵抗中的作用和机制,并根据CAF诱导耐药的潜在机制为未来研究提供建议。
