Additionally, Cytokeratin 7 and 20, CD56, synaptophysin, chromogranin, SF1, α-inhibin, WT1, desmin, SMA, GATA3, Uroplakin II, CD10, PR, CD5, BerEP4, and NUT were negative in tumor cells, no loss of INI1 expression, β-catenin showed only membranous staining without nuclear accumulation (no shown). This evidence concerns the gene SF1 and neoplasm.
