–Inhibition with 200 nM Dendrotoxin decreases preclonal expansion of thymocytes–Inhibition with 1-10 nM Dendrotoxin reduces proliferation of MCF-7 breast cancer cells–Inhibition with 100 nM Dendrotoxin arrests gefitinib-resistant H-460 NSCLC cells at G1/S and reduces tumor growth–Enhanced expression protects neurons from cell death stimuli–Downregulation or inhibition with 50 μM Agitoxin-2 in retinal ganglion cells rescues neurodegeneration–Inhibition with 50 μg/ml KAaH2 reduces proliferation of U-87 glioblastoma cells–Kv1.1 silencing decreased proliferation of HeLa cells. The gene discussed is KCNA1; the disease is glioblastoma.
