"Semaphorin 3B (SEMA3B), located at 3p21.3, is a secreted member of the semaphorin family important in axonal guidance. SEMA3B undergoes allele and expression loss in lung and breast cancer and can function as a tumor suppressor," scientists in the United States report. "Previously, we found that SEMA3B induces apoptosis in tumor cells either by reexpression or when applied as a soluble ligand. SEMA3B-induced apoptosis was mediated, in part, by blocking vascular endothelial growth factor autocrine activity in tumor cells. In the current study, treatment of lung and breast cancer cells with picomolar concentrations of soluble SEMA3B inhibited their growth; induced...
