All of these classes also have been linked with cancer cell migration (Hu and Verkman, 2006; Shi et al., 2013; Li et al., 2014; Chen et al., 2015; Zhang et al., 2016); however, H2O2 transport has thus far been linked only to AQP3 as a control mechanism in cancer cell migration. This evidence concerns the gene AQP3 and cancer.
