Core Tip
Core tip: Hypoxia-reoxygenation (H-R) treatment increases the intracellular reactive oxygen species (ROS) level to activate the MAPK/ERK pathway, resulting in the promotion of migration and invasion in colon cancer LOVO cells. Inhibition of chloride intracellular channel 1 (CLIC1) using specific inhibitor IAA94 can markedly decrease the H-R-enhanced ROS generation, migration, invasion and phosphorylation of ERK. The results presented in the current study suggest that CLIC1 is involved in the metastasis of colon cancer LOVO cells via regulating the ROS/ERK pathway in the H-R process.
