Conclusion
The results showed that metformin may suppress the proliferation and migration of VSMCs via FAK-related pathways and may retard the progression of vessel stenosis in diabetes.
Methods
The FAK gene expression levels and pFAK protein values were evaluated in VSMCs treated with different doses of metformin (1, 5 and 7 mM), based on cell viability using RT-qPCR, western blotting and MTT techniques. The cellular migration was evaluated by scratch assay.
Results
The FAK gene expression levels reduced significantly in metformin-treated VSMCs at 24 h and 48 h periods (p < .0008 and p < .0001, respectively). The pFAK protein values reduced significantly at 24 h (5 mM and 7 mM metformin doses) and 48 h periods (p < .001). In agreement with pFAK protein values, cellular migration reduced significantly at 24 h and 48 h periods (p < .001).
