Breast tumors have a higher level of PLK1 expression compared with normal breast tissue (Fig. 1E, right panel, left violin plot) and is more highly expressed in patient TNBC compared to Luminal A tumors (p = 1.01 × 10−6), this perhaps correlates with TNBC’s aggressive characteristics (Fig. 1E, right panel, right violin plot). The gene discussed is PLK1; the disease is breast neoplasm.
