Recent statistics from the American Heart Association show that 68&#37; of people aged 65 or older with diabetes die from some form of heart disease&#46; Around 50&#37; of all adults with diabetes die of CVD&#59; diabetic patients are two to four times more likely to die from heart disease than non-diabetic individuals&#46; The high mortality of these patients is even more striking considering that diabetes is one of the most manageable risk factors for CVD&#46; Indeed&#44; even if glucose levels are under control&#44; diabetic patients still suffer higher CVD-related mortality than non-diabetic individuals&#46; In this context&#44; a better insight is required into what might be happening in the heart under high glucose concentrations&#46;</p><p id="par0010" class="elsevierStylePara elsevierViewall">Hypoxia controls all steps of postischemic revascularization in all organs of the body&#44; a process that is of cardinal importance in patients with myocardial ischemia&#46; It occurs in part by activation of the transcription factor hypoxia-inducible factor 1 alpha &#40;HIF-1&#945;&#41; and other molecular partners&#46;<a class="elsevierStyleCrossRefs" href="#bib0050"><span class="elsevierStyleSup">1&#44;2</span></a> Perhaps the most important mechanism regulated by HIF-1&#945; in this context is transcription of vascular endothelial growth factor &#40;VEGF&#41;&#44; a major player in the growth of new blood vessels&#46;<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">1</span></a> Studies have shown that in the presence of elevated glucose concentrations&#44; cells and tissues are subjected to increased levels of advanced glycation end products &#40;AGEs&#41;&#44;<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">3</span></a> which are known to downregulate HIF-1&#945; function&#46;<a class="elsevierStyleCrossRefs" href="#bib0050"><span class="elsevierStyleSup">1&#44;2</span></a> AGEs are formed by the reaction of sugars such as glucose with the free amino group of certain amino acids&#44; via reversible intermediates of a Schiff base and an Amadori product&#46;<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">3</span></a> This is similar to glycosylation&#44; but requires no enzymatic activity and therefore is not regulated&#46; Often&#44; glycated proteins eventually lose their original functions&#44; which makes the process toxic to the cell&#46; Methylglyoxal &#40;MGO&#41;&#44; a byproduct of glycolysis that is elevated in diabetic patients&#44; has a &#8764;20<span class="elsevierStyleHsp" style=""></span>000-fold higher reactivity than glucose<a class="elsevierStyleCrossRef" href="#bib0065"><span class="elsevierStyleSup">4</span></a> and has been shown to inhibit the HIF-1&#945; pathway by a number of different mechanisms&#46;<a class="elsevierStyleCrossRefs" href="#bib0050"><span class="elsevierStyleSup">1&#44;2</span></a> Nonetheless&#44; the most likely cause of loss of cell response to hypoxia in most diabetic complications is destabilization of HIF-1&#945;&#44; through direct modification of the transcription factor by glucose or MGO&#44; leading to an irreversible conformational change of the protein and subsequent elimination by the cell&#39;s proteolytic systems&#46;<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">5</span></a> This hypothesis is supported by the loss of HIF-1&#945; in hypoxic tissues of patients with hyperglycemia&#46;<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">1</span></a> In this issue of the <span class="elsevierStyleItalic">Journal</span>&#44; Ramalho et al&#46; show that this is also true for cardiac muscle cells&#44; in this case the HL-1 cell line&#44; in a time- and dose-dependent manner&#46;<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">6</span></a> Interestingly&#44; even though there are reports that degradation of the HIF-1&#945; protein after glycation occurs through ubiquitination and subsequent degradation of HIF-1&#945; by the proteasome&#44;<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">5</span></a> Ramalho et al&#46; show that&#44; at least in cardiac cells&#44; proteasome inhibition is not sufficient to prevent HIF-1&#945; destabilization in the presence of MGO&#46;<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">6</span></a> Furthermore&#44; degradation of HIF-1&#945; by a proteasome-independent pathway has been described&#46;<a class="elsevierStyleCrossRef" href="#bib0080"><span class="elsevierStyleSup">7</span></a> HIF-1&#945; is degraded in the lysosome by a mechanism called chaperone-mediated autophagy &#40;CMA&#41;&#44;

under hyperglycemia have been shown to improve wound healing in diabetic mice&#46;<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">8</span></a> Most studies have focused on the use of prolyl hydroxylase &#40;PHD&#41; inhibitors such as dimethyloxalylglycine or the iron chelator deferoxamine&#46;<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">8</span></a> These compounds act by hindering the hydroxylation of HIF-1&#945; by PHDs&#44; since hydroxylation is the initial step that triggers ubiquitination and degradation of HIF-1&#945; by the ubiquitin proteasome system&#46; During hypoxia this pathway is inactive because PHDs use oxygen for hydroxylation of HIF-1&#945;&#46; In this context the new data point toward CMA as a more suitable therapeutic target for the rescue of HIF-1&#945; function in diabetes&#46; There is thus now strong evidence indicating that future research should focus on the role of CMA in the degradation of HIF-1&#945; under hyperglycemia&#44; both in cultured cells and in animal models of diabetes&#46; Compounds inhibiting degradation pathways that use the lysosome&#44; like CMA&#44; are well known and efforts are being made to find new ones&#46;<a class="elsevierStyleCrossRef" href="#bib0090"><span class="elsevierStyleSup">9</span></a> Moreover&#44; the lysosome inhibitor hydroxychloroquine is already used in malaria patients&#46; Therefore&#44; in view of Ramalho et al&#46;&#8217;s new findings&#44; it is reasonable to hypothesize that the lysosome might be a suitable target for the prevention of HIF-1&#945; destabilization and promotion of postischemic revascularization&#44; in particular in diabetic patients with myocardial ischemia in the context of CVD&#46;</p><span id="sec0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0005">Conflicts of interest</span><p id="par0020" class="elsevierStylePara elsevierViewall">The author has no conflicts of interest to declare&#46;</p></span></span>"

Recent statistics from the American Heart Association show that 68&#37; of people aged 65 or older with diabetes die from some form of heart disease&#46; Around 50&#37; of all adults with diabetes die of CVD&#59; diabetic patients are two to four times more likely to die from heart disease than non-diabetic individuals&#46; The high mortality of these patients is even more striking considering that diabetes is one of the most manageable risk factors for CVD&#46; Indeed&#44; even if glucose levels are under control&#44; diabetic patients still suffer higher CVD-related mortality than non-diabetic individuals&#46; In this context&#44; a better insight is required into what might be happening in the heart under high glucose concentrations&#46;</p><p id="par0010" class="elsevierStylePara elsevierViewall">Hypoxia controls all steps of postischemic revascularization in all organs of the body&#44; a process that is of cardinal importance in patients with myocardial ischemia&#46; It occurs in part by activation of the transcription factor hypoxia-inducible factor 1 alpha &#40;HIF-1&#945;&#41; and other molecular partners&#46;<a class="elsevierStyleCrossRefs" href="#bib0050"><span class="elsevierStyleSup">1&#44;2</span></a> Perhaps the most important mechanism regulated by HIF-1&#945; in this context is transcription of vascular endothelial growth factor &#40;VEGF&#41;&#44; a major player in the growth of new blood vessels&#46;<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">1</span></a> Studies have shown that in the presence of elevated glucose concentrations&#44; cells and tissues are subjected to increased levels of advanced glycation end products &#40;AGEs&#41;&#44;<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">3</span></a> which are known to downregulate HIF-1&#945; function&#46;<a class="elsevierStyleCrossRefs" href="#bib0050"><span class="elsevierStyleSup">1&#44;2</span></a> AGEs are formed by the reaction of sugars such as glucose with the free amino group of certain amino acids&#44; via reversible intermediates of a Schiff base and an Amadori product&#46;<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">3</span></a> This is similar to glycosylation&#44; but requires no enzymatic activity and therefore is not regulated&#46; Often&#44; glycated proteins eventually lose their original functions&#44; which makes the process toxic to the cell&#46; Methylglyoxal &#40;MGO&#41;&#44; a byproduct of glycolysis that is elevated in diabetic patients&#44; has a &#8764;20<span class="elsevierStyleHsp" style=""></span>000-fold higher reactivity than glucose<a class="elsevierStyleCrossRef" href="#bib0065"><span class="elsevierStyleSup">4</span></a> and has been shown to inhibit the HIF-1&#945; pathway by a number of different mechanisms&#46;<a class="elsevierStyleCrossRefs" href="#bib0050"><span class="elsevierStyleSup">1&#44;2</span></a> Nonetheless&#44; the most likely cause of loss of cell response to hypoxia in most diabetic complications is destabilization of HIF-1&#945;&#44; through direct modification of the transcription factor by glucose or MGO&#44; leading to an irreversible conformational change of the protein and subsequent elimination by the cell&#39;s proteolytic systems&#46;<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">5</span></a> This hypothesis is supported by the loss of HIF-1&#945; in hypoxic tissues of patients with hyperglycemia&#46;<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">1</span></a> In this issue of the <span class="elsevierStyleItalic">Journal</span>&#44; Ramalho et al&#46; show that this is also true for cardiac muscle cells&#44; in this case the HL-1 cell line&#44; in a time- and dose-dependent manner&#46;<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">6</span></a> Interestingly&#44; even though there are reports that degradation of the HIF-1&#945; protein after glycation occurs through ubiquitination and subsequent degradation of HIF-1&#945; by the proteasome&#44;<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">5</span></a> Ramalho et al&#46; show that&#44; at least in cardiac cells&#44; proteasome inhibition is not sufficient to prevent HIF-1&#945; destabilization in the presence of MGO&#46;<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">6</span></a> Furthermore&#44; degradation of HIF-1&#945; by a proteasome-independent pathway has been described&#46;<a class="elsevierStyleCrossRef" href="#bib0080"><span class="elsevierStyleSup">7</span></a> HIF-1&#945; is degraded in the lysosome by a mechanism called chaperone-mediated autophagy &#40;CMA&#41;&#44;

under hyperglycemia have been shown to improve wound healing in diabetic mice&#46;<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">8</span></a> Most studies have focused on the use of prolyl hydroxylase &#40;PHD&#41; inhibitors such as dimethyloxalylglycine or the iron chelator deferoxamine&#46;<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">8</span></a> These compounds act by hindering the hydroxylation of HIF-1&#945; by PHDs&#44; since hydroxylation is the initial step that triggers ubiquitination and degradation of HIF-1&#945; by the ubiquitin proteasome system&#46; During hypoxia this pathway is inactive because PHDs use oxygen for hydroxylation of HIF-1&#945;&#46; In this context the new data point toward CMA as a more suitable therapeutic target for the rescue of HIF-1&#945; function in diabetes&#46; There is thus now strong evidence indicating that future research should focus on the role of CMA in the degradation of HIF-1&#945; under hyperglycemia&#44; both in cultured cells and in animal models of diabetes&#46; Compounds inhibiting degradation pathways that use the lysosome&#44; like CMA&#44; are well known and efforts are being made to find new ones&#46;<a class="elsevierStyleCrossRef" href="#bib0090"><span class="elsevierStyleSup">9</span></a> Moreover&#44; the lysosome inhibitor hydroxychloroquine is already used in malaria patients&#46; Therefore&#44; in view of Ramalho et al&#46;&#8217;s new findings&#44; it is reasonable to hypothesize that the lysosome might be a suitable target for the prevention of HIF-1&#945; destabilization and promotion of postischemic revascularization&#44; in particular in diabetic patients with myocardial ischemia in the context of CVD&#46;</p><span id="sec0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0005">Conflicts of interest</span><p id="par0020" class="elsevierStylePara elsevierViewall">The author has no conflicts of interest to declare&#46;</p></span></span>"
