TUNEL assays on 5-day old Ae. aegypti dissected reproductive tissues revealed DNA breaks occurring in β2t-cifA-cifB testes which was inhibited by additional expression of cifA (β2t-cifA;β2t-cifA-cifB) whilst lowering the overall dosage of the Cifs (topi-cifA-cifB) also resulted in a lack of DNA breaks. Although wAlbB is predicted to produce two sets of nuclease CifB peptides no DNA damage was not observed in wAlbB-carrying testes. Scale bar, 50 µm.
