For validation of TP63, ELN, EFEMP1, and UCHL1 expression in adjacent normal tissue (ANT), tumor tissues (T), lymphatic metastasis-negative tumor tissues (N-), and lymphatic metastasis-positive tumor tissues (N+), we acquired RNA and immunohistochemistry (IHC) findings from TCGA and the human protein atlas (HPA). This evidence concerns the gene EFEMP1 and neoplasm.
