The results are summarized in Figure 8 and demonstrate that the protein expression of 8 genes from the transcriptomic signature, namely, FOXA1, XBP1, BLVRA, ABCA12, SIDT1, RHOB, SLC2A10, TSC22D3 is not apocrine-specific, because those proteins are frequently expressed in other types of breast cancer (Figure 8). The gene discussed is SIDT1; the disease is breast carcinoma.
