Abstract

Objective:To analyze the expression and clinical significance of solute carrier family 5 member 5 (SLC5A5), the coding gene of sodium/iodide symporter (NIS), in thyroid carcinoma.

Methods:The messenger RNA (mRNA) expression of SLC5A5 in thyroid carcinoma and normal thyroid tissues from The Cancer Genome Atlas (TCGA) was compared using independent-sample t test and results were shown in one scatter plot. The relation between clinical features of thyroid carcinoma and the changes of SLC5A5 mRNA was analyzed on LinkedOmics using Kruskal-Wallis test or Wilcoxon test.

Results:Data from TCGA showed that the SLC5A5 mRNA expression in thyroid carcinoma (1.419±0.049) was significantly reduced compared with that in normal thyroid tissues (3.301±0.087; t=12.66, P<0.01). The expression of SLC5A5 mRNA in thyroid carcinoma is affected by ethnicity (χ2=0.300, P<0.05). Moreover, the expression of SLC5A5 mRNA were decreased with the increase of pathologic grading (Ⅰ, Ⅱ, Ⅲ, Ⅳ) and T, N, M stages (χ2 values: 0.114, 0.215, z values: -0.345, -0.102, all P<0.05).

Conclusions:The expression level of SLC5A5 mRNA is associated with clinical characteristic of thyroid carcinoma. SLC5A5 mRNA has the potential to become one candidate biomarker to assess disease and predict the development of thyroid carcinoma.
