By contrast, the overexpression of HER‑2 group resulted in meningioma cell invasion, migration and proliferation being significantly enhanced, cell cycle was promoted at the G1/S‑phase and early apoptosis was decreased.
These preliminary results implicate a potential role for ErbB-2 in the benign tumourigenesis of meningioma consistent with the theoretical hierarchical interactions of homodimers of ErbB-2 that may be associated with low signal transduction.
