ARSB decline and corresponding increase in C4S mediate decline in galectin-3 that co-immunoprecipitates with C4S and increase in nuclear galectin-3. A and B, after carrageenan exposure or ARSB silencing, the galectin-3 that co-immunoprecipitated with C4S declined significantly in the NCM460 cells and in the HT-29 cells (p < 0.001). C and D, following carrageenan exposure or ARSB silencing, the nuclear galectin-3 was significantly increased in the NCM460 and HT-29 cells (p < 0.001) compared with controls. In the HT-29 cells, the increase following ARSB silencing by siRNA was significantly greater (p < 0.01) than the increase following carrageenan. E, following carrageenan ingestion, the colonic nuclear galectin-3 increased significantly (p < 0.001) over the value in the control C57BL/6J mice. F, in the ARSB-deficient mice (male and female), the nuclear galectin-3 was significantly higher than in the wild-type mice (p < 0.001). CGN, carrageenan; WT, wild-type; F, female; M, male. ***, p < 0.001.
