Effects of dried natto diet on the transcript levels of the peroxisome proliferator-activated receptor-γ, coactivator-1α and -1β, and nuclear receptor corepressor 1 genes in laying hens.
The effects of natto, a fermented soybean food, on transcript levels of hen peroxisome proliferator-activated receptor-γ (PPARG), PPARG coactivator-1α and -1β (PPARGC1A and PPARGC1B), and nuclear receptor corepressor 1 (NCOR1) were investigated using real-time polymerase chain reaction in white leghorn (Julia strain) hens. Twenty-one- and 34-week-old hens were fed a basic or 3% dried natto-supplemented diet for 8 weeks. In the 21- and 34-week-old hens fed the natto-supplemented diet, hepatic PPARGC1B and NCOR1 transcript levels and adipose and hepatic PPARG transcript levels were significantly lower, respectively, than those in the control group. Furthermore, 34- and 42-week-old hens were fed a basic diet supplemented with 3% of the protein/fiber-enriched fraction (PFB) or 0.6% of the fat-enriched fraction (FAT) of natto, respectively, for 8 weeks. Adipose PPARG transcript levels were higher in the FAT diet group and significantly lower in the PFB diet group than in the control group. However, both FAT and PFB diet groups showed significantly lower hepatic PPARG transcript levels than did the control group. These results suggest that dried natto influences the transcript levels of PPARG, PPARGC1B, and NCOR1, and the FAT and PFB of natto influence the adipose and hepatic PPARG transcript levels in hens.
