In this study, we evaluated the antiproliferative and proapoptotic effects of the isothiocyanate iberin, a bioactive agent in Brassicaceae species, in human glioblastoma cells. The human glioblastoma cell cultures were treated with different concentrations of iberin and tested for growth inhibition, cytotoxicity, induction of apoptosis, and activation of caspases. Iberin inhibited growth of tumor cells in cell proliferation assays, enhanced cytotoxicity, and induced apoptosis by activation of caspase-3 and caspase-9. Findings from this study could provide a basis for potential usefulness of the diet-derived isothiocyanate iberin as a promising therapeutic micronutrient in the prevention/intervention of brain tumors.

D005909 Glioblastoma A malignant form of astrocytoma histologically characterized by pleomorphism of cells, nuclear atypia, microhemorrhage, and necrosis. They may arise in any region of the central nervous system, with a predilection for the cerebral hemispheres, basal ganglia, and commissural pathways. Clinical presentation most frequently occurs in the fifth or sixth decade of life with focal neurologic signs or seizures.

D017209 Apoptosis A regulated cell death mechanism characterized by distinctive morphologic changes in the nucleus and cytoplasm, including the endonucleolytic cleavage of genomic DNA, at regularly spaced, internucleosomal sites, i.e., DNA FRAGMENTATION. It is genetically programmed and serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
