In addition, we observed a highly significant reduction of CL levels ( Figure 6C ) typically associated with defects in the electron transport chain and increased ROS production as they are required for the anchoring of Complex 1 in mitochondria ( Dudek, 2017 ; Quintana et al., 2010 ) Increased levels of ROS in the larval brain have been shown to disturb mitochondrial function triggering changes in lipid stores in metabolic tissues ( Martelli et al., 2020 ).
