ABSTRACT

Objective:

To study the expression and clinical significance of microRNA-574-3p (miR-574-3p) in colon cancer.

Methods:

A total of 106 colon cancer patients who were admitted to the First Hospital of Qinhuangdao and Shijiazhuang Hospital of Traditional Chinese Medicine from June 2012 to June 2015 were selected as the research objects. Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression level of miR-574-3p in colon cancer tissues and normal adjacent tissues. The relationship between the expression of miR-574-3p and the clinicopathological characteristics and prognosis of patients with colon cancer was analyzed. Immunohistochemical staining was used to detect the relationship between the expression of miR-574-3p and the expression of CyclinA2 or E-cadherin.

Results:

Compared with normal tissues adjacent to cancer, the expression level of miR-574-3p in 106 cases of colon cancer was significantly lower ( P<0.01). The decreased expression of miR-574-3p was related to tumor diameter, Dukes stage, histological grade and lymph node metastasis (all P<0.05), but not to age and tumor location (all P>0.05). The patients with low expression of miR-574-3p, high Dukes stage and histological grade, and lymph node metastasis had poor survival (all P<0.05). The 5-year overall survival rate of patients with decreased miR-574-3p expression in cancer tissue was significantly lower than that of patients without decreased miR-574-3p expression ( P=0.007 6). Compared with patients with no decreased miR-574-3p expression, patients with decreased miR-574-3p expression had higher CyclinA2 protein integrated optical density (IOD) value and lower E-cadherin protein IOD value in colon cancer tissues (all P<0.05).

Conclusions:

The decreased expression of miR-574-3p is related to the poor prognosis of colon cancer patients, which may affect tumor recurrence and metastasis by regulating the expression of CyclinA2 and E-cadherin proteins.
