| Sumario: | Developmental pathologies may result from endogenous or xenobiotic-enhanced formation of reacting oxygen species (ROS), which oxidatively damage cellular macromolecules and/or alter signal transduction, and that the embryonic processes regulating the balance of ROS formation, oxidative DNA damage and repair, and ROS-mediated signal transduction may be important determinants of teratological risk. ROS can oxidize molecular targets such as DNA, protein, lipid in a process called oxidative stress resulting in cellular dysfunction and in utero death or teratogenicity. This review, consisting of literature search of journals and chapters in books aims at highlighting the importance of the cerebellum in controlling various motor activities in the body, as well as substances affecting cerebellar development with a view of providing an insight to the role antioxidants play in cerebellar development. It is interesting to note that the developing brain (especially the cerebellum, cerebrum and hippocampus) is highly vulnerable to the deleterious effects of ROS. Studies have shown that exposure to oxidants in the first trimester is associated with an increased risk of major congenital anomalies, as most vital organs in the body develop and some become functional within this period in offspring. Antioxidants may prevent oxidative damage in degenerative diseases including ageing, cardiovascular diseases, cancer, Alzheimer's disease, stroke and Parkinson's disease as such play a critical role in wellness and health maintenance. |
