RDX and thyroid gland follicular carcinoma: However, we did not analyse the expression levels of ezrin, radixin and moesin separately and, therefore, we do not know whether the expression of any of these proteins alone constitutes a molecular signature specific for follicular thyroid carcinoma and contributes to the observed cytoskeletal, morphological and adhesive changes, or whether this is a result of all the three ERM proteins acting together.
