Abstract
Papillary thyroid carcinoma is an epithelial malignancy with follicular cell differentiation and sets of defined nuclear features and appearance of an irregular solid mass. The main objective of our study is to research on the expression of miR-218-2 in the serum of patients with papillary thyroid cancer and its clinical significance. Our study involved patients with thyroid nodules were divided into a capitate cancer group (N = 100) and a benign nodule group (N =100). Lastly, 50 cases of healthy individuals were used as controls. The total sample size was 250. All cases were clinically diagnosed and underwent histopathological examinations at the Tonglu County Hospital of Traditional Chinese Medicine between January 2023 and January 2024. Quantitative RT-PCR was used to assess the expression levels of miR-218-2 and its host gene SLIT3 in normal and cancer thyroid tissues. We found that 45% of tumour sizes were less than 1 cm with 90% of tumours did not infiltrate the glandular capsule, implying a favourable prognosis. Lastly, 85% of tumours were well differentiated with about 75% showing no metastasis while 60% of TNM stage were classified as stage I. Also, miR-218-2 and its host gene SLIT3 are significantly down-regulated in papillary thyroid carcinoma. The inhibitory effects of miR-218-2 act in synergy with its host gene SLIT3 to alter the rates of cell invasion, cell migration and cell proliferation. Our findings have clinical significance on the involvement of miR-218-2 and SLIT3. There exists a functional relationship between host genes and intronic miRNAs in the tumorigenesis of thyroid cancers.
