Abstract:Background. Chaperone proteins nucleolin (NCL, or C23) and nucleophosmin (NPM, or B23) regulate key cell functions. The most tumors are characterized by over-expression of these proteins, especially in cell nuclei and on the сell surface, as NCL. Differential expression of NCL/NPM in tumor and normal cells is the basis of selective cytotoxicity of cationic peptides – expected ligands for these proteins. Objective. Analysis of the interactions between nucleolin and some peptides with high nonspecific toxicity f… Show more
