Lactoferrin and Osteopontin Cooperatively Promote Intestinal Epithelial Maturation in Neonatal Mice by Activating the Brg1/Notch1/Hes1 Pathway.

ABSTRACT: Background/Objectives: Early life is crucial for infant gut development and intestinal homeostasis. Lactoferrin (LF) and osteopontin (OPN) are bioactive breast milk proteins that are supplemented into infant formula to promote gut development. However, the combined effect of LF and OPN (LOP) on in vivo gut maturation has not been fully elucidated. This study investigated the effects of LF, OPN, and LOP on intestinal epithelium maturation in C57BL/6N mice from postnatal days 7 to 21. Methods: 3-day-old pups were assigned to four groups: Control group, LF group: 300 mg/kg LF; OPN group: 300 mg/kg OPN, LOP group: 300 mg/kg of a 1:5 (w/w) mixture of LF and OPN. Results: Compared to controls, LOP reduced plasma Diamine Oxidase (DAO) activity by 1.54-fold and D-lactate level
