Where this comes from

Abstract

A typical case of alveolar soft part sarcoma was found to express in a strong and widespread fashion the marker MyoD1 protein. This nuclear phosphoprotein is the product of a regulatory gene that controls the commitment of a cell to myogenic lineage; it therefore provides strong and perhaps definitive evidence in support of the skeletal muscle nature of this enigmatic neoplasm.
