To examine whether the single neonatal X-irradiation alters the expressions of other genes, we measured some of the thyroid cancer-related expression markers, including Mct8, Lat4, Met, and Lgals3. MCT8 and LAT4 are thyroid hormone transporters localized in the plasma membrane of thyroid epithelial cells24. This evidence concerns the gene SLC43A2 and thyroid gland carcinoma.
