mir-9a was expressed post-developmentally to avoid muscle loss and degeneration that could confound the analysis.

Overexpression of mir-9a decreases wit mRNA levels.

Source was adults of transgenic fly line; bait produced from transgenic construct; prey produced from endogenous gene.

Mutation of mir-9a increases wit mRNA levels.

Source was adults of mutant fly line; bait produced from endogenous gene; prey produced from endogenous gene.
