In order to determine to what extent the gene expression changes uncovered in [Pten, p53]thyr−/− ATCs overlap with those identified in human anaplastic carcinomas, we retrieved from the GEO and EBI repositories two datasets containing gene expression data from a total of six control thyroids and eight ATCs. The gene discussed is TP53; the disease is Ehlers-Danlos syndrome, musculocontractural type.
