Genotoxic or metabolic stress‐induced UVRAG expression in tumour cells.Figure 1 (A,B) Expression of UVRAG under cell stress. HL60 and HCT116 cells were treated with doxorubicin (1 μg/ml), cisplatin (10 μm) and UV irradiation (5 min after 50 mJ/cm2) for the indicated time, and then apoptosis, autophagy and fluorescence intensity of UVRAG was assayed.

Figure 8(A) Respiratory chain enzyme activities of control (blue), COX1∆ (red) and COX2∆ (green) cybrids. Enzyme activities were measured in three experimental replicates. Data are expressed as the percentages of control cells, and indicated as means ± SD. Mann-Whitney U test was applied for statistical analyses. Variations between controls and mutants: α, p<0.05; γ, p<0.001. Specific variations between COX1∆ and COX2∆ mutants: ∗p<0.05. (B) Structural reorganization of SCs in the absence of CIV. In control cells (top), subunits COX4 and COX5A form an independent subcomplex that binds newly-synthesized COX1, allowing the completion of CIV assembly and its further integration into respirasomes through canonical pathways. In COX1∆ cybrids (middle), SC I+III2 is rapidly degraded due to the absence of stabilizing CIV components. In COX2∆ cybrids (bottom), SC I+III2 is stabilized by the binding of a 'non-canonical' stable COX1-submodule (comprising subunits COX1, COX5B, COX7A2 and the assembly factor HIGD2A), likely by keeping this SC in an assembly-competent state for the further incorporation of CIV subunits/modules up to completion of respirasome biogenesis.

Ectopic homeodomain TF expression changes muscle target choice in a predictive manner.Figure 4(A) Left panel: Schematic drawing of a stage 17 Drosophila embryonic head, highlighting the stereotypic innervation of the anterior feeding muscles by specific MNs, MHE (green) by MN2a, which only expresses Dfd, MHD (red) by MN3, which only expresses Scr, and LR (purple) by MN2c, which only expresses Lab. Right panel: Representative confocal images of early stage 17 Drosophila embryonic heads, highlighting the expression pattern of the anterior Hox TFs Lab, Dfd and Scr, showing that Lab is expressed in the LR muscle, Dfd in the MHE muscle and Scr in the MHD muscle. The muscles are indicated by white dashed lines. (B) Representative confocal images of stage 17 embryonic heads highlighting the expression of Dfd (purple), Myosin in muscles (blue) and FasII in axonal projections (green) in control (elav>RFP) animals and animals mis-expressing the Hox TFs Lab, Dfd and Scr by means of the elav-GAL4 driver. A zoom on the projections (FasII staining) of MN2a and MN3 to the MHE and MHD muscles of an early stage 17 Drosophila embryo are shown. Asterisks highlight the location of MN2a and MN3, respectively. MN2a is identified by the FasII expressing axonal projection emerging from a Dfd expressing MN, which normally innervates the Dfd expressing MHE muscle (as shown in the elav>RFP control), while MN3 is identified as the MN underneath MN2a, which normally innervates the MHD muscle (as shown in the elav>RFP control). The panel on the right side represents a schematic drawing of the confocal image shown on the left side, summarizing the innervation of the anterior muscles (LR, MHE, MHD) by projections emerging from MN2a (magenta) or MN3 (cyan) in control and mis-expression conditions. (C) Quantification of different phenotypes manifesting in MN2a and MN3 after Hox mis-expression in comparison to control animals: MN2a axons projecting to the MHE muscle, representing the wild-type (wt) innervation pattern of MN2a (magenta); MN3 axons projecting to the MHD muscle, representing the wild-type (wt) innervation pattern of MN3 (cyan); MN2a or MN3 axons projecting to muscles other than the MHE or MHD termed wiring defects (dark grey); abnormal synaptic morphologies at MN2a or MN3 derived axon terminals termed terminal defects (light grey). Note, each genetic experiment was performed in parallel to an adequate control experiment using the same driver line crossed to a line that controls expression of either UAS-RFP or UAS-GFPRNAi. Each experiment was performed in triplicates, innervation rates were calculated from n=16 for elav>lab, n=18 for elav>Dfd and n=25 for elav>Scr. p-values between two genetic conditions were calculated by a two-sided Fisher test. # p <0 .1, * p < 0.05, **<0.01.
Figure 4Confocal microscopy images of whole-mount preparations of mid-basal cochlear sensory epithelia from Clrn2clarinet/+ (A) and Clrn2clarinet/clarinet (B) P6 mice immunostained for actin. Despite lack of clarin-2, the developing sensory epithelium of mutants is similar to that of heterozygous controls. Confocal microscopy images of whole-mount preparations of cochlear sensory epithelia from Clrn2clarinet/+ (C), Clrn1-/- (D), and Clrn2clarinet/clarinet (E) P6 mice immunostained for stereocilin (green) and actin (red).
