Abstract:
Background: Recombinant Keratinocyte Growth Factor (rHuKGF) is a therapeutic protein
used widely in oral mucositis after chemotherapy in various cancers, stimulating lung morphogenesis
and gastrointestinal tract cell proliferation. In this research study, chitosan-rHuKGF polymeric complex
was implemented to improve the stability of rHuKGF and used as rejuvenation therapy for the
treatment of oral mucositis in cancer patients.
Objective: Complexation of rHuKGF with mucoadhesive low molecular weight chitosan to protect
rHuKGF from proteolysis and investigate the effect of chitosan-rHuKGF complex on the proliferation
rate of FHs 74 Int cells.
Methods: The interaction between chitosan and rHuKGF was studied by molecular docking. Malvern
ZetaSizer Nano Zs and Fourier-Transform Infrared spectroscopy (FTIR) tests were carried out to characterize
the chitosan-rHuKGF complex. In addition, SDS-PAGE was performed to investigate the interaction
between chitosan-rHuKGF complex and pepsin. The effect of chitosan-rHuKGF complex on
the proliferation rate of FHs 74 Int cells was studied by MTT assay.
Results: Chitosan-rHuKGF complex was formed through the hydrogen bonding proven by the docking
studies. A stable chitosan-rHuKGF complex was formed at pH 4.5 and was protected from proteolysis
and assessed by SDS PAGE. According to the MTT assay results, chitosan-rHuKGF complex increased
the cell proliferation rate of FHs 74 Int cells.
Conclusion: The developed complex improved the stability and the biological function of rHuKGF.
