(116,117,123) Nakatani et al (116,117) and Sekine et al (123) have suggested that upregulation of components in the WNT signaling pathway, such as [beta]-catenin, are important in low-grade fetal adenocarcinomas, as well as in biphasic pulmonary blastomas. This is in contrast to the high-grade fetal adenocarcinomas, which appear to be distinct from the low-grade tumors.
