Expression of ovary-specific acidic protein in steroidogenic tissues: a possible role in steroidogenesis.

abstract：:Thyroid hormones are essential for normal development and metabolism. Their synthesis requires transport of iodide into thyroid follicles. The mechanisms involving the apical efflux of iodide into the follicular lumen are poorly elucidated. The discovery of mutations in the SLC26A4 gene in patients with Pendred syndro...
