Evaluation of Protective Role of Prebiotic Galacto-Oligosaccharides Against Colon Cancer
In the present study role of treated galacto-oligosaccharides (GOS) synthesized from lactose (GOS) was assessed against development of colon cancer. Research was carried out in two phases, production of prebiotic galacto-oligosaccharide and assessment of their protective role against colon cancer. Greatest percentage of enzyme activity was observed at 6.5 pH and 37oC. Transgalactosylation process was accepted at 37°C by the using of enzymes with three different concentrations. Male Sprague Dawley rats going to treated galactooligosaccharides groups and inulin group had significantly lowest aberrant crypt foci (ACF) counts per colon in contrast to controlled animals (G1 and G5). The animals body mass belonging to galacto-oligosaccharides (Group G2, G3 and G4) increased suggestively higher as associated to control group (G1). Present results were found to be defensive in contradiction of colon cancer. Though more research is needed at DNA level to explore the mutations at gene levels.
