Abstract

SCOPE:

Formula-derived dietary advanced glycation end products (AGEs) may promote programming of inflammation and oxidative stress in the kidney of intrauterine growth retardation (IUGR) piglets.

METHODS AND RESULTS:

IUGR piglets received either a low temperature heated formula (n = 8) or a high temperature heated formula (HHF: n = 8) or suckled naturally for 3 wk postnatally. Then they were fed with normal ad libitum regular diet. N(ε)-carboxymethyllysine (CML) was measured in plasma, feces, and formula by HPLC/MS-MS. CML was detected by immunofluorescence in kidney cells. Target renin-angiotensin-apoptotic, pro-inflammatory genes-p62 NF-κB, and soluble receptor of AGE (sRAGE) levels were quantified. Compared with that in controls, free CML and plasma urea increased significantly in the HHF-fed group at PND36 (p < 0.05). CML was detected in the nuclei of renal tubular cells of formula-fed piglets but not in suckled ones. This presence of CML was associated with the activation of the soluble receptor of AGE. AT1, AT2, caspase 3, caspase 8, NF-κB, p62 NF-κB, and total protein oxidation in kidney were higher in HHF-fed group as compared to LHF-fed group (p < 0.05).

CONCLUSION:

Food processes aimed at reducing the concentration of AGEs in infant formula are urgently needed and may be therapeutically relevant for premature and/or IUGR babies.
