ABSTRACT
AIM:
To investigate the clinical characteristics of microRNA(miR)-196b in colorectal cancer(CRC)and to study its biological function in 5-fluorouracil(5-FU)resistance.METHODS:
miRNA sequence dataset and the corresponding clinical data of CRC patients were downloaded from The Cancer Genome Atlas(TCGA).Expression level and clinical characteristics of miR-196b in CRC patients were analyzed using SPSS 17.0.CRC cell line overexpres-sing miR-196b was established using transient transfection method.MTS test was used to evaluate the effect of miR-196b overexpression on 5-FU resistance.RESULTS:
miR-196b expression was associated with lymph node metastasis and TNM stage(P<0.05),but not related with age and sex.Lymph node metastasis and distant metastasis were independent prog-nostic factors for rectal patients(P<0.05).The expression level of miR-196b was not associated with survival condition of rectal patients.The viability of the cells overexpressing miR-196b treated with different concentrations of 5-FU was signifi-cantly higher than that in control group(P<0.05).CONCLUSION:
miR-196b may be a potential biomarker of TNM stage and lymph node metastasis in CRC.miR-196b increases the 5-FU resistance of CRC cells.
