Expression levels of PTEN and Rac-1 in hypoxic conditions and modulated by exosomes. A1, A2 Expression levels of PTEN and Rac-1 after growth in hypoxic conditions for 0, 24, 48, or 72 h, determined from by real-time PCR. ###P < 0.001, #P < 0.05; 0-h timepoint was used as control. B1B3 Expression levels of PTEN and Rac-1 after growth in hypoxic conditions for 0, 24, 48, or 72 h, determined by western blotting. ###P < 0.001, ##P < 0.01, #P < 0.05; 0-h timepoint was used as control. C1C3 Exosomes regulated expression of PTEN and Rac-1 in the context of hypoxia. ###P < 0.001 vs. normoxia; **P < 0.01 vs. hypoxia. Exo, exosomes; PTEN, phosphatase and tensin homolog deleted on chromosome 10; Rac-1, Ras-related C3 botulinum toxin substrate 1. Statistics calculated based on the results of three repetitions of each experiment
