The invention provides methods and compositions of selectively disrupting mitotic functions in a target cell demonstrating undesirable mitotic function. Suitable target cells include mammalian, plant and bacterial cells, which cells may be in vitro or in situ. The general methods involve introducing into the target cell an effective amount of a peptide comprising contiguous acidic amino acids, such as Asp or Glu, whereby the undesirable mitotic function of the cell is selectively disrupted. In particular embodiments, the peptide comprises a Gm2S-1 peptide, particularly a lunasin and/or alisin peptide. The peptide may be introduced by transfecting the cell with a nucleic acid encoding the peptide.

L'invention concerne des méthodes et des compositions d'interruption sélective de la fonction mitotique dans une cellule cible présentant une fonction mitotique indésirable. Les cellules cibles appropriées comprennent des cellules mammifères, végétales et bactériennes, lesquelles cellules peuvent être in vitro ou in situ. Les méthodes générales consistent à introduire dans la cellule cible une quantité efficace d'un peptide comprenant des acides aminés acides contigus, tels que Asp ou Glu, de manière à interrompre sélectivement la fonction mitotique indésirable de la cellule. Dans des modes de réalisation particuliers, le peptide comprend un peptide Gm2S-1, notamment un peptide de lunasine et/ou d'alisine. Le peptide peut être introduit par transfection de la cellule avec un acide nucléique codant le peptide.
