Quinic acid (QA) is an alicyclic organic acid widely found in plants. It accumulates in varying concentrations of plant species and is actively metabolized throughout the plant's life cycle. Wound healing after skin injury involves a complex interaction of many cells, fibroblasts, endothelial cells, and regenerated immune cells and their interrelating extracellular matrix. In our study, the healing effect of QA on scar tissue was studied. For this aim, oxidative stress, and changes in FN1 and Collogen1α gene levels were examined. For this purpose, fibroblast cells were seeded in 24, 96 and well plates for wound healing, MTT analysis and Real-Time PCR testing (respectively). Wells were drawn with a 100 µL pipette tip for wound line. As a conclusion of our study, it was determined that cell viability increased significantly, especially in the QA 20 µg-ml group at the end of 48 hours. Increased cell viability and antioxidant capacity resulted in increased cell proliferation. Both FN1 and COL1A1 gene expression levels were up regulated in the QA groups compared to the control group. Our findings show for the first time that quinic acid promotes migration and/or proliferation of fibroblasts by regulating oxidative stress and the FN1A and COL1A1 genes. This activity may be related to the production of FN1A and COL1A1, which are considered important targets for modulation of the tissue repair process.
