AKT1 overexpressed cells were found to be most sensitive to cisplatin treatment at all concentrations of cisplatin tested (0, 0.5, 1, 10, and 50 μM) in both MCF-10A and BT-549…In conclusion, our study demonstrated the varied expression of AKT isoforms in triple-negative breast cancers and also confirmed differential role of isoforms in stemness, invasiveness and response towards the cisplatin treatment.
