Also, expression of PLCD1 in N0 (Lymph node without metastasis, n = 232) and N1-3 (Lymph node with metastasis, n = 226) breast cancers was analyzed using cBioPortal for Cancer Genomics (http://www.cbioportal.org/) within The Cancer Genome Atlas (TCGA) database, and the expression of PLCD1 was much higher in N0 breast cancers compared with N1-3 breast cancers (p = 0.0264) (Figure 1D). The gene discussed is PLCD1; the disease is breast carcinoma.
