title: Metallothionein: an overview.
abstract: Metallothioneins (MTs) were discovered in 1957 by Margoshes and Vallee and identified as low-molecular weight and sulphydryl rich proteins. It is not surprising that most mammalian tissues contain age related basal levels of MTs since they are involved in metalloregulatory processes that include cell growth and multiplication. In an effort to understand the biology of this intriguing tumor, various biomarkers such as oncogenes, p53 tumor suppressor gene, waf 1 protein, proliferating cell nuclear antigen, telomerase, microsatellite markers and cytogenetic changes have been examined. One biomarker which has recently shown to be expressed in various human tumors but still less reported in carcinoma is MT. Immunohistochemical detection of MT proteins in cold acetone-fixed paraffin embedded liver sections was performed by the streptavidin-avidin-biotin immuno-peroxidase complex method.
