Consistent with the histology, comparison of untreated and siRNA control-treated cells demonstrated no significant differences in expression of BC (KRT5 and TP63), secretory (MUC5AC, MUC5B and SCGB1A1), ciliated (FOXJ1 and DNAI1) and squamous (KRT6B and IVL) markers (Fig. 2f). The gene discussed is TP63; the disease is breast cancer.
