Sumario:Bladder cancer (BC) is one of the most common human cancers. There is an interest in controlling and treating BC and other types of cancer via the use of natural substances and/or combination chemotherapy. Modified forms of pectin have been reported to possess anticancer bioactivity related to the interaction of galactosyl, a main component of pectin, with galectin-3, a carbohydrate-binding protein that is overexpressed on many types of cancer cells. In this study, the antiproliferative effect on BC of novel modified pectins extracted from olives was evaluated. Pectoliv extracts, with high polyphenol content associated to polysaccharides rich in pectin, exhibited an important antiproliferative capacity in vitro against four human BC cells lines, RT112, T24, J82, and SCaBER. Pectoliv treatment reduced the expression of galectin-1 and galectin-3 and significantly inhibited the agglutination of erythrocytes. Thus, Pectoliv may have the potential for development as a novel galectin-3 inhibitor.
