Can siRNA be used to prevent upregulation in gene expression?

the siRNA should target all sequences to which it has been targetted. In essence, it wouldn't differentiate between new wave of mRNA and the basal mRNA that is constantly being produced..so filtering between those two will be difficult, IMO.

Well, I understand that.
I am just wondering if it is doable to inject a modest amount of siRNA so that it can "clamp" mRNA levels, to prevent it from increasing.

I suppose you could knock down the endogenous expression while delivering an mRNA modified so it does not contain the knockdown target. The trick would be to tune the amount of mRNA delivered so that it matches the unperturbed endogenous expression level.
