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). Here, PRRT3 is linked to metastatic melanoma.
