In spite of the recent studies that have shown relationship between diabetes and the expression of molecular motors, as myosin-IIB [21], myosin heavy-chain [29], myosin-Va [23, 25], and myosin-IXB [30], the pathways linked among myosin expression, oxidative stress, and diabetes mellitus are still unclear. The gene discussed is MYO9B; the disease is diabetes mellitus.
