Phytochemical antioxidants modulate mammalian cellular epigenome: implications in health and disease.

abstract：:The small GTPase rac1 controls actin redistribution to membrane ruffles in fibroblasts and other cell types, as well as the activation of the NADPH oxidase in phagocytes. We explored the possibility that these two processes could be related. We used a replication-deficient adenoviral vector to overexpress the constitu...
