Since subcellular localisation of certain MUC1 isoforms has been associated with tumour cell aggressiveness and cancer prognosis [19-21], this relationship was also studied using the antibody PankoMab-GEXTM, which detects a tumour-associated epitope of MUC1 (TA-MUC1) [6]. This evidence concerns the gene MUC1 and neoplasm.
