CD97‐positive cancer cells associated with higher Ki‐67 + LNR index in patients and concomitantly expressed HLA‐DR – an MHC class II molecule, normally expressed by the antigen‐presenting cells, but also frequently identified in TNBC samples [42, 43], and pNF‐κB, a transcription factor implicated in TNBC proliferation and invasiveness with drug targeting potential [44, 45]. This evidence concerns the gene MKI67 and cancer.
