Abstract
The objective of this research was to investigate the influence of glucose on bovine lactoferrin’s (LF) conformation, thermodynamic stability and osteoblastic cell proliferation. The conformation and thermodynamic stability of LF was detected by spectroscopic and differential scanning calorimetry (DSC). The osteoblastic cell proliferation of LF at physiological concentrations (100 μg/ml) was measured by BrdU incorporation. The binding constant between glucose and LF is KSV = 5 × 10−3, and Tyr residues of LF were located in a more hydrophobic environment, while Trp residues were located in a more hydrophilic environment. LF with glucose had increased α-helix and β-sheet contents by 6 and 14 %, respectively. It showed a two-step denaturation of LF. There was a gradual changs in the denaturation temperature and the calorimetric enthalpies (ΔHcal) with a growing concentration of glucose. It has also revealed that glucose dose dependently reduced the ability of LF to increase MC 3T3-E1 cell proliferation. Increasing the binding with glucose, LF might cause to change its native state, which reduced the stimulation activity of osteoblasts cell proliferation.
