Am i the only one who clearly remembers being taught about DNA, RNA, mRNA, etc in 8th grade Biology? That was 30 years ago. I also clearly remember the teacher and textbooks talking about how messenger RNA had the potential to be used to "teach" cells how to fight infection or even be reprogrammed to get rid of cancerous growths etc
...and then in college when you took, Chemistry (both O and P), figured out that part of the formation of
memory is water soluble?
Several studies have shown that synthesis of new proteins at the synapse is a prerequisite for the storage of long-term memories. Relatively little is known about the availability of distinct mRNA populations for translation at specific synapses, the process that determines mRNA localization, and the temporal designations of localized mRNA translation during memory storage. Techniques such as synaptosome preparation and microdissection of distal neuronal processes of cultured neurons and dendritic layers in brain slices are general approaches used to identify localized RNAs. Exploration of the association of RNA-binding proteins to the axonal transport machinery has led to the development of a strategy to identify RNAs that are transported from the cell body to synapses by molecular motor kinesin. In this article, RNA localization at the synapse, as well as its mechanisms and significance in understanding long-term memory storage, are discussed.
