formation in the central and peripheral nervous system. All commonly target RNA, shooting the messenger rather silencing the message at its source (the DNA), as many other regulatory proteins do. This may give them a relatively quick response time, h...

Gene with broad role also causes prevalent, inherited nerve disorder
...impulse slows due to degradation of the protective myelin
sheath that normally covers nerve axons, Zchner explained. Axons are the cable-like extension of the neuron from the cell body in the spinal cord to the juncture, or synapse, between the nerve ending and muscle. Demyelinated axons conduct nerve impul...
