In the GSE7553 dataset, PRRT3-AS1 was found to be significantly highly expressed when comparing melanoma skin tissues to normal skin tissues, primary+metastatic melanoma skin tissues to normal skin tissues, and primary+metastatic melanoma skin tissues to primary melanoma skin tissues (Figures 3G–I), whereas DANCR showed no significant differences in any of the comparisons (Supplementary Figure 3F). The gene discussed is DANCR; the disease is metastatic melanoma.
