Ascorbic acid inhibits the migration of Walker 256 carcinosarcoma cells.

The results of several experimental studies have shown that ascorbic acid inhibits tumor growth and metastasis. Ascorbic acid is an antioxidant that acts as a scavenger for a wide range of reactive oxygen species (ROS). Both tumour metastasis and cell migration have been correlated with the intracellular ROS level, so it was postulated that the inhibitory effect of ascorbic acid derivatives on cell motility may be caused by scavenging of ROS.
