Cupressus sempervirens extract inhibited human basal cell carcinoma tumorigenesis, local invasion, and angiogenic property

Basal cell carcinoma, a noninvasive and rarely metastatic tumor, correlates with clinical and histological involvement of basal epithelial cells. It occurs due to dysregulation of hedgehog-patched1 signaling pathway. The current study was conducted to evaluate the in vitro cytotoxic effects of Cupressus sempervirens methanolic extract against primary basal cell carcinoma cells, over a period of 48 h. We measured protein level of Annexin-V and the leakage rate of lactate dehydrogenase in cells being exposed to 420 μM extract. In addition to transcript levels of PTCH-1, a receptor of of hedgehog signaling pathway, angiogenic activity of tumor cells were determined in terms of the amount of vascular endothelial growth factor and angiopoietin-2, and metastatic levels of matrix metalloproteinase 2 and 9.
