Gut and testis of tert-/- zebrafish are characterised by a time-dependent mitochondrial defects, increase of ROS levels and reduction of ATP levels.

Gut and testis of tert-/- exhibit a time dependent increase in ROS levels (A and D) and decrease of ATP levels (C and F) (N >= 3 fish per time point per genotype), determined by 2′,7′-Dichlorofluorescin diacetate (DCFDA) measurement and the CellTiter-Glo Luminescent Cell Viability Assay, respectively. Representative EM images (B and E) of these tissues at 9 months revealed fragmented mitochondrial ultrastructure (arrows) and rounded and swollen mitochondria denoting perturbed cristae (arrows) in tert-/- zebrafish (N = 3 fish). Data are represented as mean ± SEM (* p-value<0.05; ** p-value<0.01, using the Mann-Whitney test).
