Gal-3 is a galactose binding lectin, and the suggested hypothesis for the anti-cancer action of pectin is that components of chemically- or enzymatically-modified pectin extracts binds to and inhibits the biological activity of the Gal-3 (Kidd, 1996) by preventing its association with natural receptors (Sundblad, Croci, & Rabinovich, 2011). This evidence concerns the gene LGALS3 and cancer.
