Claims7
A method for modulating apoptosis of epithelial cells of a subject comprising administering to the subject a therapeutically effective amount of a tight junction protein modulator, wherein said tight junction protein modulator consists of the formula:
- G-Z1-Z2-Z3-Z4-Z5-G (SEQ ID NO:11)
- wherein
- G is glycine;
- Z1 is aspartic acid, glutamic acid, asparagine, or glutamine;
- Z2 is phenylalanine, tyrosine, tryptophan, or leucine;
- Z3 is tyrosine, phenylalanine, tryptophan, or leucine;
- Z4 is asparagine or glutamine;
- and
- Z5 is proline.
A method for removing at least a portion of epithelia cells that are in hyperplastic stages from a subject, said method comprising administering to the subject in need of such treatment a tight junction protein inhibitor, wherein said tight junction protein modulator consists of the formula:
- G-Z1-Z2-Z3-Z4-Z5-G (SEQ ID NO:11)
- wherein
- G is glycine;
- Z1 is aspartic acid, glutamic acid, asparagine, or glutamine;
- Z2 is phenylalanine, tyrosine, tryptophan, or leucine;
- Z3 is tyrosine, phenylalanine, tryptophan, or leucine;
- Z4 is asparagine or glutamine;
- and
- Z5 is proline.
