Evaluation of Downstream Regulatory Element Antagonistic Modulator Gene in Human Multinodular Goiter.

BACKGROUND DREAM (Downstream Regulatory Element Antagonistic Modulator) is a neuronal calcium sensor that was suggested to modulate TSH receptor activity and whose overexpression provokes an enlargement of the thyroid gland in transgenic mice. The aim of this study was to investigate somatic mutations and DREAM gene expression in human multinodular goiter (MNG). MATERIAL AND METHODS DNA and RNA samples were obtained from hyperplastic thyroid glands of 60 patients (54 females) with benign MNG.
