Expression of selected genes involved in transport of ions in papillary thyroid carcinoma
Abstract
Introduction: The studies of papillary thyroid cancer (PTC)
gene expression profile have shown changes in expression
of genes involved in transport of several ions. The aim of
our study was a real-time PCR evaluation of three of them:
KCNJ2, SLC4A4 and SLC34A2.
Material and methods: The analysis was carried out in PTC tumors and normal thyroid samples gained from 38 patients. Real-time quantitative PCR (Q-PCR) was performed (Taqman) with β-glucuronidase (GUS) as the reference gene.
Results: We observed 20 × increase of SLC34A2 expression in PTC. This gene encodes Na+/PO4 3- cotransporter. Considerable increase of gene expression has been shown also for KCNJ2, encoding a potassium ion channel. SLC4A4, which encodes the Na+/HCO3 2- cotransporter, exhibited a 7-fold decrease in PTC.
Conclusions: The performed study revealed that SLC34A2 gene exhibited the most distinct change in expression and may become a molecular marker of papillary thyroid cancer.
