Disruption of intramitochondrial Ca2+ homeostasis A intracellular Ca2+ production and mitochondrial Ca2+ concentrations of 4T1 cells treated with different preparations for 6 h. Scale bars were 50 μm. B–E Flow cytometry results of 4T1 cells incubated with GO-Alg@CaP and GO-Alg@CaP/C. Data are mean ± SD, n = 3; *P < 0.05, **P < 0.01 and ***P < 0.001
