(A) CCK8 assay of cellular viability at different times (24, 48, 72, and 96 h) in MAP4K1 knockdown (KD) or knockout (MAP4K1−/−) U87 and T98G cells and their control groups (NC, MAP4K1+/+), respectively (n = 15, the data were from three independent experiments). (B) 5-ethynyl-2-deoxyuridine assay of cell proliferation in MAP4K1-KD U87 and T98G or MAP4K1−/− T98G cells and their NC groups 48 h after seeding (n = 20, the data were from three independent experiments). Scale bar, 100 μm. (C) Flow cytometry analysis of the rates of dead cells, which indicates Annexin V- plus PI-positive cells 48 h after seeding (n = 3, the data were from an independent experiment, and the same experiment was repeated three times). (D) Cell cycle analysis by flow cytometry showed G2/M arrest in MAP4K1-KD or knockout glioblastoma multiforme cells 72 h after seeding (n = 3, the data were from an independent experiment, and the same experiment was repeated three times). Data are represented as the mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001. (A, B, C, D)
t tests (B, C) and two-way ANOVA (A, D).
