MMP2 and basal cell carcinoma: Moreover, 25 μM DATS inhibited the growth of both human melanoma cells and basal cell carcinoma cells by upregulating cytosolic Ca2+ mobilization and intracellular ROS production and decreasing the activities and protein expression of matrix metalloproteinase-2 (MMP-2) and MMP-9 without a significant effect on normal keratinocyte HaCaT cell growth [77].
