Abstract

To analyze the clinical significance of MATN1-AS1 as ceRNA of Mir-200b in the tissues and serum of cervical cancer patients. A total of 50 patients with cervical cancer admitted to our hospital from March 2018 to March 2019 were selected as the research objects. All patients underwent surgical resection of cancer tissues in our hospital, and cervical cancer tissues and adjacent tissues more than 2 cm away from the edge of cancer tissues were retained. Patients with cervical cancer were selected as the research group, and 50 patients with benign uterine lesions were selected as the control group. The expressions of MATN1-AS1 and Mir-200b in cervical cancer tissues and serum were detected by real-time PCR, and the correlation between MATN1-AS1 and Mir-200b was analyzed. The relationship between MATN1-AS1, Mir-200b and clinical features was analyzed, and the 3-year survival rate of cervical cancer patients was analyzed. Compared with adjacent tissues, the relative expression levels of MATN1-AS1 and Mir-200b in cancer tissues were significantly increased (P < 0.05). Compared with the control group, the relative expression levels of MATN1-AS1 and mir-200b in the study group were increased (P < 0.05). The expression levels of matn1-as1 and mir-200b were higher in poorly differentiated, tumor ≥ 4 cm, FIGO stage iii-iv, and lymph node metastasis patients (P < 0.05). Correlation analysis showed that MATN1-AS1 was positively correlated with Mir-200b (r = 0.625, P = 0.001). Compared with blank control group, the relative expression levels of MATN1-AS1 and Mir-200b in MATN1-AS1 silencing group were decreased (P < 0.05). The 3-year survival rate of 48 patients with cervical cancer was 66.67% (32/48). The survival rate of patients with high expression of MATN1-AS1 was lower than that of patients with low expression of MATN1-AS1, and the survival rate of patients with high expression of Mir-200b was lower than that of patients with low expression of Mir-200b (x2 = 4.251, 5.244, P = 0.011, 0.008). There is a potential binding point between MATN1-AS1 and Mir-200b. The expressions of MATN1-AS1 and Mir-200b are increased in the tissues and serum of cervical cancer patients, and they are positively correlated. Silencing of MATN1-AS1 in cervical cancer cell lines can reduce the expression of Mir-200b. Matn1-as1 can regulate the expression of Mir-200b and participate in the occurrence and development of cervical cancer.
