RNA SHOWING NEURON SURVIVAL ACTIVITY

摘要

The present invention provides an in-vitro-derived component which permits identification of essential components contained in an extracted fraction having physiological activities such as a survival activity on neuron, particularly to spinal cord motoneuron, and is useful for diagnosis, prevention and therapy of various diseases including neurodegenerative diseases. The RNA of the present invention has a base sequence represented by the sequence No.1 of the sequence table, exhibiting a very high survival activity relative to spinal cord motoneuron.
