mRNA expression of MMPs and TIMPs. a-d Real time PCR showed a decrease in MMP-2 and MMP-9 mRNA levels, and an increase in TIMP-1, TIMP-2, and TIMP-3 mRNA levels. The results were displayed as percentage of controls, Error bars represent the means ± SD, n = 5; * p = 0.051, **p = 0.005, ***p < 0.001,****p < 0.0001
