RESUMO

One of the most prevalent types of cancer worldwide today is gastric intestinal (GI) tumors. To guarantee their lives, people with a developed GI require palliative care. This covers the application of targeted medicines in addition to chemotherapy treatments including cisplatin, 5-fluorouracil, oxaliplatin, paclitaxel, and pemetrexed. Because of the evidence of drug resistance emerging in poor patient outcomes and prognoses, determining the exact process of medication resistance is motivated. Besides, it is noteworthy that exosomes and noncoding RNAs, like microRNAs and long non-coding RNAs (lncRNAs), produced from tumor cells are implicated in both GI medication resistance and the carcinogenesis and development of GI disease. Biochemical events related to the cell cycle, differentiation of cells, growth, and pluripotency, in addition to gene transcription, splicing, and epigenetics, are all regulated by noncoding RNAs (ncRNAs). Therefore, it should come as a wonder that several ncRNAs have been connected in recent years to drug susceptibility and resistance as well as tumorigenesis. Additionally, through communicating directly with medications, altering the transcriptome of tumor cells, and affecting the immune system, exosomes may govern treatment resistance. Because of this, exosomal lncRNAs often act as a competitive endogenous RNA (ceRNA) of miRNAs to carry out its role in modifying drug resistance. In light of this, we provide an overview of the roles and processes of ncRNA-enriched exosomes in GI medication resistance.
