Adult tracheal cells express core components of the circadian clock. (A) Schematic overview of the circadian clock in Drosophila. (B) Normalized read count (RPKM) values of clock coding genes for Clock (Clk), cycle (cyc), period (per), timeless (tim) and cryptochrome (cry). Bars show mean with SD, n = 4. Asterisks indicate a differential gene expression based on the RNA-Seq analysis. (C) Microscopic confirmation of in vivo Tim expression in abdominal adult trachea.
