THE PRELIMINARY STUDY ON THE CHANGES IN THE EXPRESSION OF G PROTEINS ? SUBUNIT mRNA IN THYROID TUMOR / 解放军医学杂志

ABSTRACT

To investigate the changes in the expression of G proteins ? subunit mRNA in non functioning thyroid adenoma (NFTA) and thyroid papillary cancer (TPC). Eleven thyroid specimens were obtained during surgery, 6 of which from patients with NFTA and 5 from patients with TPC. The expression levels of stimulating and inhibiting G protein ? subunit mRNAs were determined by reverse transcription polymerase chain reaction (RT PCR). The expression levels of Gsa mRNA in TPCs were significantly higher than those in normal thyroids and NFTAs( P
