UASt regulatory sequences drive expression of a 70 nucleotide mir-6-1 microRNA that contains a 21bp fragment which is complementary to Dark coding regions in one strand of the mir-6-1 stem region.
Expression of ArkmiRNA.Scer\UAS under the control of Scer\GAL4CCAP.PP strongly suppresses the programmed cell death of CCAP neurons in the adult ventral nerve cord after eclosion.
