Also, how much is there to say? These miRNA's are great findings and indicate a new way to regulate gene expression. It is a fine tuning of the system and the extent of it is still hardly known.

In this system, it is quite interesting that the genes they are regulating by cleavage are themselves transcription factors -- ie they themselves are genes that regulate gene expression.

It's a quick way to turn off the genes regulated by scarecrows.

I find that cleavage piques my interest in genetic expression....

(OK, so I'm in the gutter again.)
