MicroRNA 155 Downregulation by Vitamin C–Loaded Human Serum Albumin Nanoparticles During Cutaneous Wound Healing in Mice

This study focused on potential of vitamin C loaded human serum albumin (HSA) nanoparticles for treatment of wound. Nanocarrier were prepared and assessed for their effect on growth of 3T3 fibroblast cells, cell migration, wound healing rate and expression of miR-155, TGF-β1 and SMAD 1,2 genes. Wound healing assay was done and wounds were treated with vitamin C loaded HSA nanoparticles. Nanoparticles were prepared with size and zeta potential of 180±6 and -29 mV, respectively. Vitamin C loaded HSA nanoparticles showed controlled release of vitamin C into the buffer solution. Also, yield and encapsulation efficacy of loaded nanoparticles were obtained as 70.6 and 52.1 %, respectively. MTT results showed that the growth of 3T3 fibroblast cells was promoted in culture medium with 20 µg/ml of vitamin C loaded HSA nanoparticles. Cell migration assay indicated the positive effect of loaded nanoparticles on wound healing. The in-vivo results showed that the rate of wound healing was increased after treatment wit...
