Antioxidant and Wound Healing Property of Gelsolin in 3T3-L1 Cells

الملخص EN

Delineation of factors which affect wound healing would be of immense value to enable on-time or early healing and reduce comorbidities associated with infections or biochemical stress like diabetes.

Plasma gelsolin has been identified earlier to significantly enable injury recovery compared to placebo.

This study evaluates the role of rhuGSN for its antioxidant and wound healing properties in murine fibroblasts (3T3-L1 cell line).

Total antioxidant capacity of rhuGSN increased in a concentration-dependent manner (0.75-200 μg/mL).

Cells pretreated with 0.375 and 0.75 μg/mL rhuGSN for 24 h exhibited a significant increase in viability in a MTT assay.

Preincubation of cells with rhuGSN for 24 h followed by oxidative stress induced by exposure to H2O2 for 3 h showed cytoprotective effect.

rhuGSN at 12.5 and 25 μg/mL concentration showed an enhanced cell migration after 20 h of injury in a scratch wound healing assay.

The proinflammatory cytokine IL-6 levels were elevated in the culture supernatant.

These results establish an effective role of rhuGSN against oxidative stress induced by H2O2 and in wound healing of 3T3-L1 fibroblast cells.
