Abstract:
In recent years, many researchs have found that microRNA (miRNAs) has differential expression in pancreatic tissues, pancreatic cancer cells and drug-resistant pancreatic cancer cells, and miRNAs can change the sensitivity of pancreatic cancer cells to chemotherapy drugs by acting on downstream target genes.The molecular mechanism of drug resistance in tumors is complex. In the drug-resistance of pancreatic cancer, miRNAs can mediate drug resistance in pancreatic cancer cells by affecting epithelial-mesenchymal transformation, DNA damage and repair, downstream signaling pathways, non-coding RNA, related coding genes, pancreatic cancer stem cells and other mechanisms. Therefore, the investigation of drug resistance mechanism and related miRNAs in pancreatic cancer will help to find new anti-drug resistance treatment methods. The authors summarize exosome miRNAs invloved in regulating chemoresistance in pancreatic cancer, in order to provide theoretical support for clinical treatment and find new targeted therapy of pancreatic cancer.
