- Abstract
- Pax8 and TTF-1 are transcription factors involved in the morphogenesis of the thyroid gland and in
the transcriptional regulation of thyroid-specific genes. Both proteins are expressed in few tissues
but their simultaneous presence occurs only in the thyroid where they interact physically and
functionally allowing the regulation of genes that are markers of the thyroid differentiated
phenotype. TAZ is a transcriptional coactivator that regulates the activity of several transcription
factors therefore playing a central role in tissue-specific transcription. The recently demonstrated
physical and functional interaction between TAZ and TTF-1 in the lung raised the question of
whether TAZ could be an important regulatory molecule also in the thyroid. In this study, we
demonstrate the presence of TAZ in thyroid cells and the existence of an important cooperation
between TAZ and the transcription factors Pax8 and TTF-1 in the modulation of thyroid gene
expression. In addition, we reveal that the three proteins are co-expressed in the nucleus of
differentiated thyroid cells and that TAZ interacts with both Pax8 and TTF-1, in vitro and in vivo.
More importantly, we show that this interaction leads to a significant enhancement of the
transcriptional activity of Pax8 and TTF-1 on the thyroglobulin promoter thus suggesting a role of
TAZ in the control of genes involved in thyroid development and differentiation. (literal)
