Serum metallothioneins in childhood tumours – A potential prognostic marker

Abstract

Metallothioneins (MT) are low molecular weight, cysteine-rich proteins maintaining metal ions homeostasis. They play a role in carcinogenesis and may also cause chemoresistance. The aim of the study was to explore the importance of MT serum levels in children suffering from malignant tumours. This prospective study involves examination of 865 samples from 172 patients with malignant tumours treated from 2008 to 2011 at University Hospital Motol. MT serum levels were determined using differential pulse voltammetry–Brdicka reactionMetallothioneins (MT) are low molecular weight, cysteine-rich proteins maintaining metal ions homeostasis.
