In IBD patient\u2019s colon, ER stress marker Bip and CHOP positive macrophage infiltration was detected in both inflammatory and tumor areas. The level of fluorescence labeled M6~G1M9 oligosaccharides increased in the LPS-treated RAW 264.7 macrophages, while thapsigargin or D-allose had no effect. In Caco-2 cells, D-allose suppressed phosphorylated AMPK expression, reduced migratory activity.
