The present invention provides an application of
thyroid hormones and its analogues in preparation of drugs for treating alpha-
thalassemia, especially in preparation of drugs for regulating expression of zeta-
globin gene. During differentiation of K562 cells,
thyroid hormone analogue (
Triac) can significantly up-regulate the expression of zeta-
globin gene (HBZ) by 50 folds or above. The expression of zeta-
globin gene (hbae5) can also be up-regulated by 30-70 folds in
zebrafish treated with
thyroid hormones and
thyroid hormones analogues. Therefore, according to the present invention, the expression of zeta-
globin gene can be significantly activated by
thyroid hormones and its analogues, which may develop new potential therapies for patients with alpha-
thalassemia. It provides an economical, safe and
effective method for treating alpha-
thalassemia and can be widely used.
