Further, TRAF3IP2-silenced cells showed a significant increase in the number of cells in G0/G1 phase (P < 0.001) and a marked decrease in S and G2 phases (P < 0.05), indicating that silencing TRAF3IP2 inhibits proliferation of malignant U87 glioblastoma cells (Figure 1H). Here, TRAF3IP2 is linked to glioblastoma.
