To demonstrate the relevance of NcDase in human cancer clinical data, we used the TIMER 2.026, QUANTISEQ27,28 and CIBERSORTER web29 resources to analyze the association between NcDase expression and TME composition in public clinical breast cancer data sets for four subtypes of BRCA (Breast invasive carcinoma) including luminal A (LumA), luminal B (LumB), Her2-enriched (Her2), and basal-like (Basal). This evidence concerns the gene ERBB2 and breast carcinoma.
