Background:

Methimazole (MMI) is an inhibitor of ICAM-1 (intercellular adhesion molecule-1) gene transcription via modulating the function of STAT1 (signal transducer and activator of transcription 1) [1].
ICAM-1 (intercellular adhesion molecule-1), also named as CD54, is a member of IGSF (immunoglobulin super-family adhesion molecule) which is expressed on endothelial cells and immune system cells [2]. It is encoded by ICAM-1 gene, ICAM-1 functions via binding to LFA-1 (lymphocyte function associated molecule-1) or Mac-1. It has shown that ICAM-1 abnormally expressed in patients with autoimmune thyroid diseases. Through modulating the function of STAT1 (signal transducer and activator of transcription 1), methimazole could inhibit the transcription of ICAM-1[1].
Methimazole is an inhibitor of ICAM-1 expression while H2O2 and IFN-γ both could heavily enhance the expression of ICAM-1. When tested with the modified FRTL-5 rat thyroid cells, using 500 μM methimazole pretreated the cells could inhibit the induction of ICAM-1 RNA by H2O2 and IFN-γ [1].
In tadpoles with methimazole treatment, the gene expression of thyroid hormone response was increased [3]. Through administering rats with methimazole, the CH (congenital hypothyroidism) offspring could be obtained for further research [4]. In the study, Sprague Dawley rats could be made as hypothyroid model for further research via giving 0.025% methimazole [5]. Using pregnant C57Bl/6 mice model, it was shown that methimazole could be used for mice or rat without causing gross external malformations [6].
