A diverse range of gastrointestinal tract disorders are called gastrointestinal (GI) malignancies. The transformation of normal cells into precursor cells, precursor cells into premalignant cells, and premalignant cells into cancerous cells is facilitated by the interaction of many modifiable and non-modifiable risk factors. Developing relevant therapy alternatives based on a better knowledge of the illness's aetiology is essential to enhance patient outcomes. The exosome is crucial in regulating intercellular interaction because it may send molecular signals to nearby or distant cells. Exosomes produced from cancer can introduce a variety of chemicals and vast concentrations of microRNA (miRNA) into the tumour microenvironment. These miRNAs significantly impact immunological evasion, metastasis, apoptosis resistance, and cell growth. Exosomal miRNAs, or exosomal miRNAs, are essential for controlling cancer resistance to apoptosis, according to mounting data. Exosomal miRNAs function as an interaction hub between cancerous cells and the milieu around them, regulating gene expression and various signalling pathways. Our research examines the regulatory function of exosomal miRNAs in mediating interactions between cancer cells and the stromal and immunological cells that make up the surrounding milieu.
多种胃肠道疾病被称为胃肠道(GI)恶性肿瘤。正常细胞向前体细胞转化、前体细胞向癌前细胞转化、癌前细胞向癌细胞转化,这一过程受到许多可改变和不可改变的风险因素的相互作用的促进。基于对疾病病因学的更好了解,开发相关的治疗替代方案对于提高患者的治疗效果至关重要。外泌体在调节细胞间相互作用方面非常重要,因为它可以向附近或远处的细胞发送分子信号。癌细胞产生的外泌体可以向肿瘤微环境中引入多种化学物质和大量的微小 RNA(miRNA)。这些 miRNA 显著影响免疫逃逸、转移、凋亡抵抗和细胞生长。越来越多的数据表明,外泌体 miRNAs 或外泌体 miRNAs 对于控制癌症对凋亡的抵抗至关重要。外泌体 miRNAs 作为癌细胞与其周围环境之间的相互作用枢纽,调节基因表达和各种信号通路。我们的研究探讨了外泌体 miRNAs 在调节癌细胞与构成周围环境的基质和免疫细胞之间相互作用中的调节功能。
