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). The gene discussed is ERBB2; the disease is invasive breast carcinoma.
