a Growth curves of MCF7 cells stably expressing HA synthase 2 (HAS2) or naïve MCF7 cells treated with BYL719 at increasing concentrations for 4 days. Data are represented as the mean (±SD). *p < 0.05. b AKT/mTOR signaling was evaluated in MCF7/HAS2 cells treated with 1 μM BYL719 with or without an HAS inhibitor (4-methylumbelliferone, 0.2 μM) for 3 days. c AKT/mTOR signaling was evaluated in MCF7/HAS2 cells treated with BYL719 (1 μM), BYL719 (1 μM) plus hyaluronidase (hyal), or the combination of BYL719 and an HAS inhibitor (0.2 μM) for 24 h. d The proliferation of MCF7/HAS2 cells treated with BYL719 (1 μM), BYL719 (1 μM) plus hyaluronidase (hyal), or the combination of BYL719 and an HAS inhibitor (0.2 μM) for 3 days was determined. Each value is the mean (±SD). *p < 0.05 vs. control, n = 5.
