| Lunasin is a novel peptide with great potential as a nontoxic chemopreventive drug. This compound might account for part of the anticancer effects reported from studies with soybean (Glycine max). We studied its isolation, purification and biological assay, and observed that both its band from soybean and one from synthetic lunasin were <5 kD in their molecular weights. Among all the crop varieties tested, only the soybean produced a lunasin band on our western blot. Levels of this peptide ranged from 0.045 mg per gram of seed for the Hanbatkong cultivar to 0.156 mg per gram seed for 'Poolunkong'. The effect on colony formation by lunasin from different soybean extracts was significantly higher than for either the positive control or the synthetic lunasin. When lunasin was present in those natural extracts, histone acetylation decreased 100% compared with cells that were treated with Na-butyrate. |
