Underexpression of C-myc in adrenocortical cancer: a major pathogenic event?

The protooncogene c-myc is a major factor in tumourigenesis. Whereas c-myc overexpression is considered to be a general feature of many tumours, we have recently demonstrated c-myc underexpression in adrenocortical cancer by a meta-analysis. We hypothesise that c-myc underexpression might be a central event in adrenortical tumourigenesis based on network topology modelling and previous experimental observations. In this brief hypothesis, we present our arguments and their possible relevance. © Georg Thieme Verlag KG Stuttgart · New York.
