Wound healing is a complex biological process in which many molecules, including microRNA molecules, play an essential role in its regulation. It is well-established that reducing miR-155 expression can accelerate wound healing. This study investigated the effect of using nanoparticles loaded with vitamin C on miR-133, collagen I, and III expressions. In this study, first, nanoparticles of albumin protein were produced and then loaded with vitamin C. 3T3 mouse fibroblast cells were affected by these nanoparticles, and cell behavior was investigated to evaluate the toxicity and appropriate doses. In addition, the expression of collagen I and III genes was studied. The results showed that nanoparticles containing vitamin C in 20 µg/ml concentration had a positive effect on collagen I and III expressions compared to the control group. Moreover, we observed a decrease in the expression of miR-133 in comparison to the control group. Therefore, according to the results of this study, it can be argued that nanoparticles containing vitamin C can significantly decrease the expression of the miR-133 gene and lead to collagen I and III gene overexpression in fibroblasts cells, which is directly effective in wound healing.
