CADM1 and meningioma: Differential gene expression studies have not commonly been done in canine meningioma; however, previous studies in the dog reported several specific genes that were differentially expressed included those coding for ribosomal proteins, CREG, and TSLC1 among others[34–36].] We have identified a set of 125 differentially expressed (DE) genes in the tumor samples compared to control meninges, which do not include ribosomal protein genes, CREG, or TSLC1.
