Abstract
Crystal violet staining (n = 6) at day 11 post-seeding demonstrates that mutation of the conserved aspartic acid residue into alanine in the S9pep N-terminus only slightly reduces S9pep effect on DLD-1 cell growth compared with wild type S9pep. By contrast, SOX9K205-G225 abolishes the S9pep effect on DLD-1 cell growth.
