Additionally, BmKCT, a scorpion venom peptide from Buthus martensii Karsch, specifically targets chloride channels in glioma cells and downregulates MMP-2 expression, thereby inhibiting proliferation, invasion, and migration of glioma cells C6 and U251 (glioma) cells (Table 4) [137,138]. This evidence concerns the gene MMP2 and glioma.
