Alteration of the levels of Activin signaling in adult fruit fly thoracic muscle did not change the overall autophagy activities in those tissues. (A-D) Thoracic muscle tissues of 19-day old female fruit flies of four different genotypes were imaged for autophagosomes labeled by Lysotracker (red) and for F-actin of muscle fibers stained by CytoPainter Phalloidin-iFluor 488 (green). (A) Babo receptor knockdown muscle tissues. (B) Smox knockdown muscle tissues. (C) Daw over-expression muscle tissues. (D) Myo over-expression muscle tissues. No significant difference of autophagosomes from the thoracic muscle tissues of the four different genotypes of fruit flies was seen (P>0.05).
