Is physiological aging inevitable too? A growing cadre of biologists says no, thanks to developments in the field of epigenetics, which studies the processes that determine how our genes &ldquo;express&rdquo; themselves in directing our cells throughout our lives.<\/span><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">If you imagine your DNA, as a piano keyboard, then epigenetics determines how the keys play music. The primary players in this concert are molecular substances that affix to our genome and leave markers. These markers, in turn, give cells specialized functions and regulate how they function. If too many markers accumulate&mdash;if there is too much &ldquo;epigenetic noise&rdquo;&#8211;the directions become muddled, and the cells become dysfunctional.<\/span><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">Recently, researchers learned that these markers can offer a remarkably accurate measurement of your biological age. That insight led to a more startling finding that epigenetic markers not only measure aging but help cause it.<\/span><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">When researchers at Harvard added epigenetic accretions to the genomes of young mice, they experienced an accelerated loss of muscle and bone mass, turned gray, lost sight and became more easily confused.<\/span><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">The results of these experiments are helping solidify an &ldquo;information theory&rdquo; of aging, which says that an accumulation of epigenetic noise interferes with genetic data. The chaos eventually causes cells to become senescent and stop reproducing and influence adjacent cells to do the same. That is the experience we call aging.<\/span><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">The origins of this process can be found in the earliest era of microscopic life on earth. Simple organisms evolved signals to reproduce cells when conditions were favorable and to shut down and attend to any damage when conditions were poor.<\/span><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">We suffer from aging, as a side effect of a primeval program that regulates and repairs our cells. As such, aging is like cancer, which also evolved as a survival mechanism, allowing cells to abandon higher functionality.<\/span><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">Before we knew why cancer happens, we considered it just a part of life. Now, we correctly call cancer a disease, and fight against it. We should regard aging in the same way, because a disease is a condition that prevents the body\/mind from working normally!<\/span><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">Aging is therefore &ldquo;the mother of all diseases.&rdquo; While smoking increases the risk of getting cancer several-fold, at 50 the risk of cancer increases over 100 times, compared to a 30 year old. At 70, it is over 500 times. Aging is also a major factor in heart disease, dementia, stroke, and Type 2 diabetes.<\/span><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">Curing any one of these diseases, increases the average lifespan by only a few years, because the risk of all of those other diseases continues to increase, thanks to the driving force of aging. But reduce them all, by addressing conditions at the cellular level, and the potential for extending productive, healthy human lives is much more significant.<\/span><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">There is no law of biology that says we must age at the rate at which we do now. Other forms of life don&rsquo;t. The bristlecone pine can survive for 5,000 years and does not appear to experience aging.<\/span><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">The jellyfish known as <a href=\"?p=1071\"><span style=\"color: rgb(0, 0, 255);\">Turritopsis dohrnii<\/span><\/a> is made up of cells that can reverse and become juvenile cells, and seems to be functionally immortal.<\/span><\/span><\/p>\n<p style=\"text-align: center;\"><span style=\"color: rgb(0, 0, 255);\"><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\"><strong>If a retina can be rejuvenated, what else can?<\/strong><\/span><\/span><\/span><\/p>\n<p><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">Epigenetic markers of deterioration\/aging can accumulate from unhealthy behaviors, like if our DNA is damaged by sun overexposure, or poor diet, or smoking. If we can reboot the cell, we would have the potential to stem or reverse cellular aging. It would allow an older body to heal and to fight against age-related diseases more like young people do.<\/span><\/span><\/p>\n<p><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">At the Salk Institute, researchers showed that the lifespan of mice suffering from premature aging could be extended by 30% by transiently turning on 4 genes that are known to wipe out accumulated epigenetic markers and induce &ldquo;pluripotency,&rdquo; the ability of a cell to develop into any other form of cell in an adult body. By partially resetting the program, the mice seem to have experienced a taste of what life is like as an immortal jellyfish.<\/span><\/span><\/p>\n<p><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">In the Sinclair lab at Harvard, researchers administered a combination of 3 genes to blind old mice and turned the genes on for 3 weeks. The treatment rejuvenated their optic nerve cells and restored their vision. If something as complex as a retina can be rebooted to a youthful state, potentially multiple times, what else can?<\/span><\/span><\/p>\n<p><span style=\"font-size: small;\"><span style=\"font-family: Verdana;\">Dr. Sinclair and others have started a company to develop medicines for eye diseases based on this science.
