The function of exosome-derived miRNAs in gastric cancer / 中华检验医学杂志

ABSTRACT

Gastric cancer, a common malignant tumor in digestive system with high morbidity as well as mortality rate, is insidious at the onset and lack of effective treatments so far. A growing number of studies have shown that exosome-derived miRNAs play an important role in the occurrence and development of gastric cancer. Autocrine exosome miRNAs from gastric cancer cells regulated tumor growth, recurrence, metastasis and drug resistance, etc. Moreover, exosomal miRNAs in the tumor microenvironment can be delivered into cancer cells to facilitate intercellular communication, thus affecting the progress of gastric cancer. Due to exosomes, which were released into circulation from tumor cells, contain abundant, specific and stable miRNAs, exosome-derived miRNAs have a great potential to be used as novel diagnosis biomarkers and treatment targets of gastric cancer.(Chin J Lab Med, 2018, 41 499-502)
