It just dawned on me that we might be able to cure diseases associated with individual genes that code for specific proteins, by simply suppressing the resultant mRNA. This could be accomplished by flooding cells with molecules that are highly reactive with the mRNA produced by the “bad gene”, and also flooding cells with the mRNA produced by the correct “good gene”. This would cause the bad gene to fail to produce the related protein (presumably the source of the related disease), and instead cause the cell to produce the correct protein of a healthy person since they’re given the mRNA produced by the good gene.
