Evaluation of Apoptotic, Antiproliferative, and Antimigratory Activity of Origanum syriacum against Metastatic Colon Cancer Cells
Published 2019“…OSEE showed a concentration-dependent apoptotic and antiproliferative effect on LoVo and SW620 cells at 500 μg mL−1 or higher after 48 h of exposure. Additionally, OSEE inhibited the migration of both LoVo and SW620 cells by decreasing (50–75%) wound-healing capacity at 500 and 1,000 μg mL−1. …”
