Transcriptomic characterization of the impact of 2''-fucosyllactose supplementation on intestinal adaptation following ileocecal resection.

Purpose: To identify the impact of 2''-FL supplementation on adaptive response following extensive intestinal resection. Methods: Transcriptomic profiles were obtained from mice undergoing ileocecal recection (8-10 week old male mice) and again at 8 weeks post-surgery. At the time of resection and again at 8 weeks post-op, small bowel samples were obtained from treatment and control animals and submitted for mRNA profiling. During these 8 weeks treatment animals (n=3) received 2''-FL supplementationion while controls (n=3) received only standard diet. Results: We observe enrichment in genes and pathways related to anti-microbial peptides, metabolism, and energy processing. Supplementation of 2''-FL increases energy availability and enhances the adaptive response. Overall design: Male C57BL/6 mice at 8 to 10 weeks of age were submitted to ileocecal recection. Following resection, half were supplemented with 2''-FL for 8 weeks; small bowels were obtained and submitted for mRNA profiling,
