there has been much evidence suggesting that microRNAs &#40;miRNAs&#41;&#44; a class of small non-coding RNAs involved in post-transcriptional gene repression&#44; have an emerging role in cancer&#44; acting mainly as tumor suppressors&#46;<a class="elsevierStyleCrossRef" href="#bib0220"><span class="elsevierStyleSup">3</span></a> It has also been suggested that miRNAs&#44; which regulate cellular processes such as proliferation&#44; cell invasion&#44; migration&#44; adaptation to hypoxia&#44; apoptosis&#44; or angiogenesis&#44; may be involved in lung tumorigenesis in COPD patients&#46;<a class="elsevierStyleCrossRef" href="#bib0225"><span class="elsevierStyleSup">4</span></a> In fact&#44; the expression of several miRNAs in induced sputum&#44; bronchoalveolar lavage or lung tissue has shown to be lower in currently-smoking patients with COPD than in healthy subjects&#46;<a class="elsevierStyleCrossRef" href="#bib0230"><span class="elsevierStyleSup">5</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">Recently&#44;

many methylated miRNA genes have been found in patients with lung cancer&#44;<a class="elsevierStyleCrossRef" href="#bib0265"><span class="elsevierStyleSup">12</span></a> and previous reported studies from our group have shown that the methylation of miR-7 is an event related to tumor progression in lung cancer cells that is also present in early stages in NSCLC patients&#46;<a class="elsevierStyleCrossRef" href="#bib0275"><span class="elsevierStyleSup">14</span></a> miR-7 methylation modulates the redox response through its direct target gene MAFG&#44;

COPD patients may also suffer from other conditions related to severity of airflow limitation&#44; such as hypoxemia&#44; or take drug therapies&#44; which may be associated with differential DNA methylation&#46; Regarding hyperinflation&#44; in a cohort of 848 COPD patients followed for 4&#8211;5 years&#44; we have recently reported that hyperinflation is an independent risk factor for the development of lung cancer&#46;<a class="elsevierStyleCrossRef" href="#bib0355"><span class="elsevierStyleSup">30</span></a> Lastly&#44;

similar to hyperinflation&#44; the decrease in DLCO is a marker for the severity of CT-detected emphysema&#46;<a class="elsevierStyleCrossRef" href="#bib0360"><span class="elsevierStyleSup">31</span></a></p><p id="par0095" class="elsevierStylePara elsevierViewall">Although our study is not able to define the mechanisms responsible for the miR-7 hypermethylation in the emphysema phenotype&#44; some evidence available leads us to speculate that it could be due to smoking-induced up-regulation of matrix metalloproteinases as well as excessive inflammatory and oxidative stress responses&#46;<a class="elsevierStyleCrossRefs" href="#bib0210"><span class="elsevierStyleSup">1&#44;32</span></a> Emphysema is characterized by a proteinase&#47;antiproteinase imbalance&#44;

aberrant methylation has been described in tissues exposed to specific types of inflammation&#46;<a class="elsevierStyleCrossRef" href="#bib0380"><span class="elsevierStyleSup">35</span></a> Finally&#44; matrix-degrading enzymes are essential for the development of emphysema&#44; and the overexpression of some of these enzymes&#44; such as matrix metalloproteinase 9&#44; has been linked to epigenetic promoter methylation&#46;<a class="elsevierStyleCrossRef" href="#bib0385"><span class="elsevierStyleSup">36</span></a></p><p id="par0100" class="elsevierStylePara elsevierViewall">Although one would expect oxidative stress induced by tobacco smoke to increase the miR-7 methylation rate&#44; we have not found a relationship with the intensity of smoking evaluated by the pack-year rate&#44; probably because we had recruited patients with a prolonged and intense history of exposure to smoking&#46; In fact&#44; our results agree with those from a large cohort of COPD-active smokers or -ex-smokers&#44; in whom the pack-year rate was not a predictive factor for lung cancer risk&#46;<a class="elsevierStyleCrossRef" href="#bib0390"><span class="elsevierStyleSup">37</span></a></p><p id="par0105" class="elsevierStylePara elsevierViewall">Another aspect to consider is the potential influence of treatment with inhaled corticosteroids&#44; as DNA methylation is regulated by three classes of DNA methyltransferases &#40;DNMTs&#41; and glucocorticosteroids have an inhibitory effect on DNMT1 and DNMT3A expression&#46;<a class="elsevierStyleCrossRef" href="#bib0270"><span class="elsevierStyleSup">13</span></a> In fact&#44; they regulate the expression of several miRNAs which target genes involved in regulation of metabolism&#44; differentiation&#44; proliferation and cell survival&#46;<a class="elsevierStyleCrossRef" href="#bib0395"><span class="elsevierStyleSup">38</span></a> Although the effect on methylation is more frequent in systemic steroids&#44;<a class="elsevierStyleCrossRefs" href="#bib0305"><span class="elsevierStyleSup">20&#44;39</span></a> budesonide may also induce changes in methylation status&#46;<a class="elsevierStyleCrossRef" href="#bib0405"><span class="elsevierStyleSup">40</span></a> In our opinion&#44; the difference in the use of inhaled corticosteroids among our COPD patients does not seem to justify the differences found in miR-7 methylation levels&#44; which are similar between patients treated or not with these drugs&#46; In fact&#44; the differences among COPD phenotypes are maintained after adjusting for previous treatment with inhaled corticosteroids&#46; Perhaps the DNMT3B expression&#44; which is also responsible for &#8220;de novo&#8221; DNA methylation in cancer&#44;<a class="elsevierStyleCrossRef" href="#bib0410"><span class="elsevierStyleSup">41</span></a> is not affected by inhaled corticosteroids&#46;</p><p id="par0110" class="elsevierStylePara elsevierViewall">Our study presents several limitations&#46; First&#44; it is a cross-sectional study that simply demonstrates differences in a biomarker related with the development of lung cancer among different COPD phenotypes&#46; In order to establish that COPD patients with higher miR-7 methylation levels have a higher risk for lung cancer&#44; it will be necessary to complete the longitudinal follow-up of this cohort in coming years&#46; Second&#44; there are differences in certain patient characteristics among the different COPD phenotypes&#44; to which we have tried to adjust the comparison of miR-7 methylation levels&#46; However&#44; the analysis we have done does not completely rule out that one of these factors may partially contribute to the differences found&#46; Third&#44; miR-7 methylation levels have been evaluated systemically instead of in lung tissue due to the greater accessibility of this source&#44; that allows a none-invasive approach&#46; Fourth&#44; our results are from a single-center cohort&#44; and their verification is necessary in patients with COPD from other settings and with other characteristics&#44; which may influence their epigenetic regulation&#46;</p><p id="par0115" class="elsevierStylePara elsevierViewall">In conclusion&#44; our study demonstrates that patients with different clinical COPD phenotypes present different levels of miR-7 methylation&#44; which is more intense in patients with the emphysema phenotype and shows an independent relationship with hyperinflation and a decline in lung diffusion capacity&#46; This finding could provide biological plausibility to previous evidence that shows that the COPD-lung cancer relationship is heterogeneous and varies between the different phenotypes of the disease&#46; Future studies will need to clarify whether miR-7 methylation levels could be a useful biomarker for the appropriate selection of COPD patients with an optimal risk-benefit ratio in lung cancer screening programs&#46;</p></span><span id="sec0050" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0120">Funding</span><p id="par0120" class="elsevierStylePara elsevierViewall">This study was supported by the <span class="elsevierStyleGrantSponsor" id="gs1">&#8216;Fondo de Investigaci&#243;n Sanitaria-Instituto de Salud Carlos III&#8217;</span> &#91;<span class="elsevierStyleGrantNumber" refid="gs1">PI15&#47;00186</span> and <span class="elsevierStyleGrantNumber" refid="gs1">PI18&#47;00050</span> to I&#46;I&#46;C&#46;&#44;

our results are from a single-center cohort&#44; and their verification is necessary in patients with COPD from other settings and with other characteristics&#44; which may influence their epigenetic regulation&#46;</p><p id="par0115" class="elsevierStylePara elsevierViewall">In conclusion&#44; our study demonstrates that patients with different clinical COPD phenotypes present different levels of miR-7 methylation&#44; which is more intense in patients with the emphysema phenotype and shows an independent relationship with hyperinflation and a decline in lung diffusion capacity&#46; This finding could provide biological plausibility to previous evidence that shows that the COPD-lung cancer relationship is heterogeneous and varies between the different phenotypes of the disease&#46; Future studies will need to clarify whether miR-7 methylation levels could be a useful biomarker for the appropriate selection of COPD patients with an optimal risk-benefit ratio in lung cancer screening programs&#46;</p></span><span id="sec0050" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0120">Funding</span><p id="par0120" class="elsevierStylePara elsevierViewall">This study was supported by the <span class="elsevierStyleGrantSponsor" id="gs1">&#8216;Fondo de Investigaci&#243;n Sanitaria-Instituto de Salud Carlos III&#8217;</span> &#91;<span class="elsevierStyleGrantNumber" refid="gs1">PI15&#47;00186</span> and <span class="elsevierStyleGrantNumber" refid="gs1">PI18&#47;00050</span> to I&#46;I&#46;C&#46;&#44;
