Contributing to aging is a protean list of processes, among them, genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, deregulated nutrient-sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion and altered intercellular communication.<\/p><\/blockquote>\n<p>Partridge\u2019s theory is taken from George Williams\u2019s seminal paper of 1957. \u00a0He writes in response to Medawar\u2019s program of isolating the root causes of aging in a small number of physiological processes:<\/p>\n<blockquote><p>Any such small number of primary physiological factors is a logical impossibility if the assumptions made in the present study are valid. This conclusion banishes the &#8220;fountain of youth&#8221; to the limbo of scientific impossibilities where other human aspirations, like the perpetual motion machine and Laplace&#8217;s &#8220;superman&#8221; have already been placed by other theoretical considerations. Such conclusions are always disappointing, but they have the desirable consequence of channeling research in directions that are likely to be fruitful. \u00a0<em>[<a href=\"http:\/\/sageke.sciencemag.org\/cgi\/content\/abstract\/2001\/1\/cp13\">Williams, 1957<\/a>]<\/em><\/p><\/blockquote>\n<p>But this perfectly reasonable conjecture of Williams was proven to be dead wrong in the 1990s, as single genes were discovered that offered dramatic life extension in worms. \u00a0There are now dozens of such genes known, and many of them are genes that need to be <b><i>disabled<\/i><\/b>, not new genes that need to be added to the genome. \u00a0In other words, there are powerful, known <b><i>pro-aging mechanisms<\/i><\/b> that make promising targets for pharmaceutical intervention. \u00a0Throwing a monkey wrench into an existing metabolic pathway is what Big Pharma knows best how to do (e.g., seratonin re-uptake inhibitors, beta blockers, COX2 inhibitors). \u00a0What we need is an inhibitor of pro-aging genes.<\/p>\n<p>Rapamycin seems to be the first candidate in this category, and it is being appropriately explored, as reported in this space last week.<\/p>\n<p>Here\u2019s a caveat: The easiest path to life extension is through <a href=\"http:\/\/en.wikipedia.org\/wiki\/Caloric_restriction_mimetic\">caloric restriction mimetics<\/a>. \u00a0In other words, trick the body into thinking it has less food than it is really eating. \u00a0Some of the early genetic modifications in worms worked in this way. \u00a0DAF-2 was an early discovery, doubling life span of worms in Kenyon\u2019s lab when it was partially disabled [<a href=\"http:\/\/kenyonlab.ucsf.edu\/Kenyon_et_al_Nature.pdf\">1993<\/a>]. \u00a0The catch is that lab worms are champions of adjustable life span. \u00a0They are exquisitely adapted to be able to survive months at a time with no food at all, but to die within a few days once they have plenty to eat. \u00a0Larger animals also live longer when they eat less, but the effect is much smaller. \u00a0My guess is that CR potentially adds 5-10 years to human life span&#8211;nothing to sneeze at, but not the big, dramatic gains we might hope for in the long run. \u00a0If we find a really, really good caloric restriction mimetic, we might hope to capture most of that 5-10 years.<\/p>\n<p>This is the low-hanging fruit being chased by the lion\u2019s share of private investment in anti-aging medicine today. \u00a0No doubt, it will be achieved in short order (though it may be decades before we know which strategy works best, because longevity data in humans takes a long time to compile.)<\/p>\n<p>Neglected is the potential for much greater gains that go beyond the potential of CR mimetics.<\/p>\n<p>Let\u2019s go back to Partridge\u2019s \u201cprotean list\u201d of complicated processes that have to be addressed:<\/p>\n<ol>\n<li><i>telomere attrition &#8212; <\/i>This is a primary aging clock, cause of\u00a0many downstream effects.<\/li>\n<li><i>epigenetic alterations &#8212; <\/i>Gene expression changes with age. \u00a0When we are in our teens, gene expression is modified to halt growth and initiate puberty. \u00a0When we get old, a similar process leads to a gene expression profile that gradually destroys the body on an accelerating schedule.<\/li>\n<li><i>genomic instability &#8212;<\/i> This is DNA damage, and by far the greatest source comes from short telomeres. \u00a0Telomeres cap the ends of a chromosome and keep it from unraveling. \u00a0When the telomere is too short, the chromosome becomes unstable. \u00a0So this may be traceable to #1. =&gt;<em> See comment below by Bowles for another mode of genomic instability, this one controlled by epigenetic markers.<\/em><\/li>\n<li><i><i>loss of proteostasis &#8212;<\/i> <\/i>This refers to protein mis-folding, which is observed in Alzheimer\u2019s Disease among other diseases of old age. \u00a0But proteins are being created and folded and re-cycled all the time. \u00a0Part of the reason that mis-folded proteins accumulate with age is simply that the body\u2019s repair mechanisms are slowing down. \u00a0Another part is (my guess) that genes that take care of this function are being down-regulated&#8211;in other words, we might trace this problem to #2 as primary cause.<\/li>\n<li><i>deregulated nutrient-sensing &#8212;<\/i> This is loss of response to insulin, related to \u201cmetabolic syndrome.\u201d \u00a0I believe this happens under epigenetic control.<\/li>\n<li><i>mitochondrial dysfunction &#8212;\u00a0<\/i>This is the \u201cfree radical theory\u201d or \u201cmitochondrial free radical theory\u201d, still invoked despite <a href=\"https:\/\/scienceblog.com\/joshmitteldorf\/2013\/09\/02\/new-take-on-free-radicals\/\">all the evidence against it<\/a>. \u00a0It\u2019s true that we have fewer mitochondria as we age, and that the mitochondria process energy less efficiently. \u00a0But the activity and the reproduction of mitochondria are under control of the cell nucleus, hence this, too, will prove to be a symptom and not a root cause of aging.<\/li>\n<li><i>cellular senescence &#8212;\u00a0<\/i>barely distinguishable from #1, telomere attrition.<\/li>\n<li><i>stem cell exhaustion &#8212;\u00a0<\/i>primarily caused by telomere attrition.<\/li>\n<li><i><i>altered intercellular communication &#8212;\u00a0<\/i><\/i>hormone signals through the blood are under epigenetic control.<\/li>\n<\/ol>\n<p><strong><em>Thus the \u201cprotean list\u201d of nine complications derive largely from two ultimate sources: telomere loss and epigenetic reprogramming. \u00a0These should be our primary targets for anti-aging

href=\"http:\/\/singularityhub.com\/2014\/11\/11\/exponential-medicine-craig-venter-estimates-5-million-complete-human-genomes-sequenced-by-2020\/\">Sequence a million human genomes<\/a>. \u00a0Look for patterns, e.g., what do the genomes of people who don\u2019t get Alzheimer\u2019s Disease have in common. \u00a0In my opinion, this is a cumbersome approach, inspired by successes in information processing, rather than knowledge of biology. \u00a0As I said, I think aging is controlled by epigenetics, and the largest gains will be made when we learn to re-program the epigenetic profile of an old person to make it look more like a young person.<\/p>\n<p>CALICO, then, is crucial. \u00a0Their direction is not yet determined, and will be shaped by\u00a0Kenyon&#8217;s vision and beliefs. \u00a0Kenyon has ambition and a wide-open imagination, and she is open to ideas about programmed aging. \u00a0We can hope that\u00a0her extensive experience with worms informs but does not limit her vision.<\/p>\n<p><strong><strong>\u00a0<\/strong><\/strong><\/p>\n<p><b>Foundation funding<\/b><\/p>\n<p>Historically, <a href=\"http:\/\/www.ellisonfoundation.org\/\">Ellison Foundation<\/a> has been one of the most reliable sources of big bucks for innovative research, with about $400 million in aging-related grants since 1997. \u00a0But last year, Ellison <a

Aubrey\u2019s paradigm. \u00a0To their credit, SENS is looking seriously at long-term projects that show potential for major gains in life span. \u00a0But, at least from my perspective, they are neglecting the most promising avenues, because Aubrey does not believe it is possible that aging might \u00a0be controlled by biochemical signaling. \u00a0The \u201cengineering\u201d approach to

theory<\/b><\/p>\n<p><strong><strong>\u00a0<\/strong><\/strong>In the long run, the greatest damage has been done indirectly, by capitalist ideology that has infiltrated the culture of evolutionary science. \u00a0From the beginning, Darwin\u2019s theory was hijacked by \u201csocial Darwinism\u201d which twisted the theory to create justification for hereditary class privilege in British society. \u00a0\u201cFitness\u201d was elided with \u201cfinancial success\u201d. \u00a0\u201cNatural selection\u201d became a sanction from Natural Law for income inequality.<\/p>\n<p>In the first half of the 20th Century, Darwin\u2019s theory was re-cast as a modern science, with quantitative measures, equations, and predictions. \u00a0The work was spearheaded by <a href=\"http:\/\/mnstats.morris.umn.edu\/introstat\/history\/w98\/RAFisher.html\">R.A. Fisher<\/a>, who happened to be both a prodigious genius in statistical theory, and also an elitist\/<a href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/17324811\">eugenicist<\/a>. \u00a0The version of evolutionary theory that was bequeathed to us was further caricatured by Richard Dawkins as the <a href=\"http:\/\/en.wikipedia.org\/wiki\/The_Selfish_Gene\">Selfish Gene<\/a>. \u00a0In this version of evolution, the emphasis is on individual competition to the exclusion of cooperation. \u00a0There is little room for self-sacrifice, and such obviously communal adaptations as sexual reproduction have become inscrutable mysteries.<\/p>\n<p>This kind of theoretical foundation has made the biological community blind to clear and manifest signs that aging is an epigenetic program, akin to growth and deveopment. \u00a0When you are a teenager, genes are turned on that cause secretions of sex hormones, and reproductive function is awakened. \u00a0When you are in your 60s and after, another set of hormones is switched on epigenetically, and the body becomes hyper-inflamed, auto-immune, insulin resistant and self-destructive. \u00a0Most biologists look at these changes and they figure that the body must know what it is doing, that there must be a redeeming positive benefit for these changes, and it would be dangerous to second-guess the body\u2019s wisdom. \u00a0But the truth is that these late-life epigenetic changes have little benefit, and their predominant purpose is to destroy the body on an accelerating time scale.<\/p>\n<p>Most researchers are busy asking themselves what goes wrong. \u00a0Neglected is the process plain and clear, where the body is being destroyed by \u201cwhat goes right\u201d.<\/p>\n<p>It follows that the greatest opportunities for radical anti-aging are to characterize the chemical signals that control aging, and to adjust the signaling environment of an old body to make it more like a young body.<\/p>\n<p>To some extent, this can be accomplished simply by lengthening telomeres, which have a substantial epigenetic reach of their own (<a href=\"https:\/\/repositories.tdl.org\/utswmed-ir\/bitstream\/handle\/2152.5\/459\/baurjoseph.pdf?sequence=3&amp;isAllowed=y\">TPE<\/a>). \u00a0There are knowledgable advocates in the field who think <a href=\"https:\/\/books.google.com\/books?id=nOJqAAAAMAAJ\">lengthening telomeres is the most important thing we can do<\/a>. \u00a0It is certainly the most accessible path, and should be a high near-term research priority.<\/p>\n<p><strong><strong>\u00a0<\/strong><\/strong><\/p>\n<p><b>My candidate for basic research: <\/b><b><br \/>\n<\/b><b>Study the Epigenetic Clock that Controls Development as well as Aging<\/b><\/p>\n<p>Biological science today does not know how the onset of puberty is timed. \u00a0We know that epigenetic changes are triggered at an appropriate age, and a few key sex hormones initiate the onset of fertility. \u00a0What we don\u2019t know is how the body detects that the time has come for this to happen, whether there is an internal clock mechanism, and if so, how it works. \u00a0To me, this would be one of the most valuable studies in basic science, and I believe that when the epigenetic\/developmental clock is understood, the results will carry over directly to understanding of the aging clock. \u00a0And if we can reset the aging clock, it\u2019s a whole new ballgame.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We can all agree that priorities in research for a longer, healthier human life span are far from rational. \u00a0Among the distorting influences are Leap-frogging ahead to medical research in a field where the basic science is not yet fully understood.
