Some discoveries and creations share the same premise: <\/span>making the invisible visible<\/b>. In this month’s Snapshot, art and medicine come together to reveal the structures that sustain life.<\/span><\/p>\n

To explore the convergence between electronic art and molecular cardiology, we’re joined by visual artist and \u201cla Caixa\u201d Foundation fellow <\/span>Isabel Merchante<\/b>, and also researcher <\/span>Jos\u00e9 Jalife <\/b>from our network, head of the Cardiac Arrhythmias group at the Carlos III National Centre for Cardiovascular Research (CNIC) and head of <\/span>the study, published in the journal <\/b>Nature<\/i><\/b><\/a>,<\/span> which explores the use of molecules present in the body to prevent acute arrhythmias <\/b>and normalise the heart’s rhythm.<\/span><\/p>\n

We\u2019ll start with the artist.<\/i><\/b><\/p>\n

Isabel Merchante<\/b><\/a> develops sculptures and installations that integrate robotics, programming, and artificial intelligence. Her projects<\/span> transform technology into an emotional and poetic tool<\/b> to reimagine how we interact with it beyond purely productive purposes. Her latest work, <\/span>Constellation Creatures<\/i><\/b>, has been constructed using machine learning techniques to create a language spoken by two robotic agents and transmitted through light and color, exploring how artificial systems are capable of creating their own languages beyond the scope of human perception.<\/span><\/p>\n

 <\/p>\n

Isabel, which artwork or artist does this image remind you of?<\/i><\/b><\/h4>\n

Isabel (I): <\/b>It reminds me of the installation <\/span>Pulse Topology<\/span><\/i><\/a> by the artist Rafael Lozano-Hemmer, a piece of electronic art that’s<\/span> activated in real time by the presence of visitors<\/b>, using the biometric data from their heartbeats. He’s an artist I admire and a leading figure internationally in electronic art.<\/span><\/p>\n

 <\/p>\n

When you look at it, what does this image bring to mind?<\/i><\/b><\/h4>\n

I: <\/b>I see a digital surface that’s expanding as if it were a biological culture, or it could also be an aerial view of a city lit up at night. <\/span>If I had to give it a name, it would be <\/b>Digital Topography<\/i><\/b>.\u00a0<\/b><\/p>\n

 <\/p>\n

We continue with the researcher <\/i><\/b>Jos\u00e9 Jalife<\/i><\/b><\/a>.\u00a0<\/i><\/b><\/p>\n

Jos\u00e9, from a scientific perspective, what can we see in this image?<\/i><\/b><\/h4>\n

Jos\u00e9 (J): <\/b>The image shows a <\/span>segment of a heart cell <\/b>from the left ventricle, specifically a section of a <\/span>T-tubule<\/b>, which are invaginations of the cell\u2019s plasma membrane that <\/span>work alongside the cardiac muscles<\/b>. Stained with fluorescent antibodies, we can see proteins forming <\/span>Kir2.1 potassium channels <\/b>(green) and <\/span>NaV1.5 sodium channels <\/b>(red), whilst the yellow dots indicate colocalisation.\u00a0<\/span><\/p>\n

\u00a0<\/span><\/p>\n

What have you discovered from this study?\u00a0\u00a0\u00a0<\/i><\/b><\/h4>\n

J:<\/b> Our data suggest that <\/span>polyamines<\/b> (small molecules present in all living organisms that are involved in cell growth and division, and are also used as supplements), specifically spermine and spermidine, are effective in <\/span>treating short QT syndrome type 3 (SQTS3)<\/b> in an experimental mouse model of the disease. SQTS3 is <\/span>a very rare genetic heart condition<\/b> that can cause fainting or even sudden death <\/span>due to irregularities in the heart rate and rhythm caused by abnormalities in the potassium and sodium channels <\/b>of the cardiac cells, which are responsible for repolarising the heart.\u00a0<\/span><\/p>\n

 <\/p>\n

What problem does your finding address, and how have you resolved it?<\/i><\/b><\/h4>\n

J: <\/b>It addresses the need to deepen our understanding of the mechanisms responsible for this condition and to <\/span>find targeted treatments<\/b>.\u00a0<\/span><\/p>\n

To do so, we used mice with the same genetic mutation. When we administered polyamines to them, their heart rate normalised and <\/span>the risk of dangerous arrhythmias decreased<\/b>. However, although the results are promising, confirming that this treatment is safe and effective in humans is required before it can be implemented in clinical practice. <\/span>Further research conducted alongside specialized medical personnel <\/b>and a Research Ethics Committee is needed, as are <\/span>clinical trials<\/b> in patients for whom standard therapy has failed, proves intolerable, or is unavailable. Additionally, establishing a <\/span>formal collaboration with a pharmaceutical partner<\/b> that complies with Good Manufacturing Practice (GMP) regulations and provides a standardized, verifiable chemical profile of the molecules will be essential.<\/span><\/p>\n

 <\/p>\n

What impact do you think this discovery will have on society?<\/i><\/b><\/h4>\n

J: <\/b>The most significant aspect is that it has demonstrated that, beyond existing treatments for symptoms such as arrhythmia, it’s possible <\/span>to develop a safe therapy that targets the molecular cause<\/b> of the problem, paving the way for new, more specific therapeutic strategies.\u00a0\u00a0<\/span><\/p>\n

Furthermore, <\/span>this discovery helps to repurpose medicines, <\/b>an approach that seeks to find new uses for existing drugs, thereby saving time and money in the development of treatments, particularly for rare diseases.\u00a0<\/span><\/p>\n

 <\/p>\n

We\u2019ll finish, as always, with a reflection on what links science and art.\u00a0<\/i><\/b>Isabel, what do you think the relationship is between the two?<\/i><\/b><\/h4>\n

I: <\/b>I think they feed off each other and there isn\u2019t really much difference between them. Science and art deal with uncertainty and their <\/span>discoveries or creations enrich people\u2019s lives<\/b>.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
