Figure Lengend Snippet: FIGURE 8 Twelve weeks of high-fat diet induced mitochondrial remodeling through fission, fusion, and BNIP3-dependent autophagy and mitophagy mechanisms. (a) markers of mitochondrial dynamics (fission and fusion) and (b) representative blots. (c) whole-cell autophagy and (d) representative blots. (e) markers of mitophagy in mitochondrial subfractions (subsarcolemmal [SSM] and intermyofibrillar [IMFM]) and (f) representative blots. Whole-cell lysates are from quadriceps and isolated mitochondria are from gastrocnemius. Data displayed as mean ± SD. Effects of diet and exercise were evaluated using two-way ANOVA. Images on representative blots come from separate membranes and channels.

Venn diagrams show the total number of identified BNIP3 interacting proteins by mass spectrometry in the human (red) and rat (green) HFrEF LV myocardium. The intersection between the two Venn diagrams (black circle) shows the number of commonly identified BNIP3 interacting proteins in human and rat samples. (B,C). Heat maps and PCA plots show the relative log2-fold expression and the variance in biological samples, respectively, in Sham and HFrEF in the rat LV myocardium of the 516 common identified BNIP3 interacting proteins (left), including those that were differentially expressed in HFrEF vs. Sham, taking a cutoff p-value of < 0.05 (right).

Heat maps show the relative log2-fold expression in Sham and HFrEF in the rat LV myocardium of some of the important identified BNIP3 interacting proteins that were commonly identified in rat and human HFrEF samples, presented by HFrEF vs. Sham cutoff p-value < 0.05 (left), 0.05 < p < 0.1 (middle), and p > 0.1 (right).

Figure Lengend Snippet: Figure 8. Schematic drawings highlight some of the key findings of the effect of BNIP3 knockdown in the rat pressure overload HFrEF model. These are presented as ShL vs. Sham (A) and ShB vs. ShL (B). The green and red color intensities show the degree of downregulation and upregulation of activity, respectively, or the log2-fold change in protein or phosphosite expression, as noted by the scale bar at the bottom right side of the schematic drawing. The double-headed arrows show the interaction between BNIP3 and its interacting protein. The blue and orange colors show whether there was inhibition/downregulation or activation/upregulation as a result of this interaction. The straight black arrows point to an effect of BNIP3 on protein phosphorylation. The black asterisk denotes

doi: 10.1111/jcmm.14898

Figure Lengend Snippet: Increased levels and mitochondria localization of BNIP3 were identified upon treatment with anticancer drugs. A, B, A549 cells (2 × 10 5 ) were treated with cisplatin (2 μg/mL), LBH589 (100 nmol/L), or rapamycin (100 nmol/L), or a combination of two drugs for 24 h (A) or 48 h (B). The mRNA or protein levels of BNIP3 were detected by qRT‐PCR (A) or Western blot (B), respectively. C, A549 cells were transfected with pEGFP‐BNIP3 plasmid. Sixteen hours later, cells were treated with anticancer drugs for 24 h. Fluorescent dye‐labelled mitochondria were detected using fluorescence microscopy upon treatment of 2 nmol/L of tetramethylrhodamine methyl ester perchlorate (TMRM) for 30 min. Results are representative of at least three independent experiments. ** P < .01 compared with untreated cells

Figure Lengend Snippet: A proposed model for the role of BNIP3 and autophagy in chemotherapeutic drug‐induced cell death. Anticancer drugs augment Binp3 and autophagy in lung cancer cells. Anticancer drugs induction of mitochondrial membrane insertion of BNIP3 may promote ROS and potential membrane loss, resulting in apoptotic or necrotic cell death. However, anticancer drug‐induced autophagy may also be involved in cell survival
