Overexpression of miR-1 causes arrhythmias in the adult fly heart. (A) M-mode traces illustrate arrhythmic heart contractions with cardiac miR-1 overexpression (tinCΔ4Gal4/UASmiR-1). (B–D) Statistical analysis of heart contraction in miR-1–overexpressing adult hearts. (E) Cardiac qPCR of fly Cdc42 (DmCdc42) and potassium channels slowpoke (slo) with tinCΔ4Gal4/UASmiR-1. Heart-specific overexpression of miR-1 resulted in reduced cardiac expression of Cdc42 and slo. *, P < 0.05.
