The expression levels of IGF-I and IGF1R were reduced, whereas the level of IGFBP-3 was normalized after Bifidiobacterium longum BAA-999 (with or without lycopene) was administrated to CD-A male mice in an azoxymethane-dextrane sulfate sodium-induced CRC model [223]. Here, IGF1R is linked to colorectal carcinoma.
