Abstract:

The comprehensive treatment effect of the majority of patients with advanced cancers is still desirable,so the early diagnosis of cancers is important. MicroRNAs(miRNA)are a class of non-coding small RNAs that exist widely and have various biological functions. More and more studies have shown that the dysregulated expression of specific miRNA caused by genetic or epigenetic changes plays a role in carcinogenesis,malignant progression. In view of the fact that miRNA can stably exist in blood,urine,cerebrospinal fluid,saliva and other biological fluids or secretions. Compared with blood and other fluid-based biopsies,urine-based biopsies have the advantages of easy handling and non-invasive sampling,so the research of urinary miRNA as a potential new tumor molecular marker has attracted more and more attention. This review summarizes the research progress of urinary miRNA as a non-invasive biomarker in the recent years. It makes a preliminary prospect for its possible clinical application in the future,and puts forward some urgent problems to be solved,so as to provide useful enlightenment for future related research.
