Generation of NeuMitoFAP zebrafish. |
Transmitted light micrographs of NeuMitoFAP zebrafish: tThe right column shows larvae that were exposed to MG2I from 3 dpf; the left column shows untreated zebrafish. The first row shows larvae at 5dpf prior to light exposure. The second row shows larvae at 5dpf immediately after exposure to 60 J/cm2 light at λpeak=661nm. The subsequent rows show larvae at daily intervals (6–9 dpf) following light exposure at 5dpf. Although the MG2I-treated, light-exposed larvae showed loss of motor responses that did not recover during the time course of the experiment (see text), there were no major morphological abnormalities at any time point. |

Disruption of mitochondrial structure in NeuMitoFAP zebrafish exposed to MG2I and far-red light. |
NeuMitoFAP zebrafish larvae were treated with MG2I or no chemical from 3 to 5 dpf and then exposed to 60 J/cm2 light at λpeak=661 nm, following which they were fixed immediately for electron microscopy. ( |
