Abstract

OBJECTIVE: Human lactoferrin (hLF), a major protein in human milk, has been shown to exert multiple biological activities. To achieve some of the benefits of breast-fed infants, we investigated the feasibility of adding commercially available bovine LF (CbLF) to infant formula. SUBJECTS AND METHODS: An intestinal enterocyte model (Caco-2 cells) was used to compare the ability of bovine LF (bLF) purified by our laboratory and CbLF with hLF to resist digestion, bind to the receptor, and exert bioactivities, including cellular proliferation, differentiation, interleukin 18 secretion, and transforming growth factor-β1 expression. RESULTS: bLf and CbLF, which are partially iron (Fe)-saturated, can bind additional Fe, partially resist digestion either dissolved in phosphate buffered saline or in the presence of infant formula at conditions similar to those of the infant gastrointestinal tract, and bind to Caco-2 cells in a manner similar to hLF. bLF and CbLF, as well as bound Fe, also are internalized by Caco-2 cells, as demonstrated by I and Fe labeling, albeit to somewhat less of an extent than hLF. CbLF promoted cell proliferation and differentiation to an extent similar to that of bLF and hLF, but these effects were not seen when the LF samples were saturated with Fe (holo-LF). Native forms of hLF and bLF significantly increased expression of transforming growth factor-β1, and holo-forms of LFs stimulated interleukin 18 secretion significantly, with the highest results for CbLF. CONCLUSIONS: CbLF is biologically active and is likely to exert several of the bioactivities of hLF if added to infant formula.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
