摘要: Object Meningiomas are benign extraaxial tumors with a slow progression. Some of them, in spite being nature, may show an aggressive progression pattern. To investigate the behavioral characteristics meningiomas, researchers have studied matrix metalloproteinases (MMPs), their tissue inhibitors (TIMPs), interstitial collagens, proteins, vascular endothelial growth factors (VEGF), and tumor necrosis factors. Methods In this study, authors investigated MMP2 TIMP2 gene polymorphisms formalin-fixed paraffin-embedded samples obtained from meningioma patients who had previously undergone surgery at authors' institution. addition, brain invasion, Ki-67 index, MMP-2 TIMP-2 expressions were using immunohistochemical methods.
