This week’s anti-aging news Jan 31, 2009

More research progress on telomerase

Telomerase is the wonderful enzyme that offers the possibility of stopping and reversing the aging clock in cells.  Astragaloside IV, one of the key firewall substances in the anti-aging regimen, is intended to activate telomerase. The central known action of telomerase is to lengthen telomeres, the end-segments of chromosomes.  Telomeres naturally shorten ever time a cell divides.  When telomeres get too short cell-senescense sets in resulting in cancers and other bad stuff like organ degeneration.  Through activated telomerase expression, cell and possibly organ immortality and much longer lives might be achieved.  At least that is the hope.  However the protein structure and exact mode of action of telomerase is still only partially understood, even after being the subject of intense study for over a dozen years now.

Telomerase is a very complex enzyme containing many proteins which serve various functions.  See the discussions about it in the Anti-Aging Firewalls treatise.  This week, discovery of a new protein called TCAB1 was reported by researchers at Stanford University. The protein seems essential for the complex process of binding new ends to telomeres to take place.  Roughly speaking, TCAB1 is required for transportation of the telomere proteins to chromosome ends.  While the research is motivated by a desire to inhibit telomerase expression as a means of controlling cancers rather than promote it, the knowledge is equally applicable to understanding of cell aging.   This is another small piece in the immense puzzle that is slowly revealing the detailed mechanisms of aging and the possible interventions against it.

Mating with a female and male sexual longevity

There seems to be no end to the things that can contribute to aspects of “normal” longevity.  One of the latest reported this week is a study done at the University of Pennsylvania School of Veterinary Medicine that shows for mice at least, living and mating with a female adds up to 20% in the longevity of fertility of males – up to 6 months longer which is a very long time in the life of a mouse.  Apparently, co-habiting with a female generates signals that upregulate genes and hormones to make this possible.  Whether the same phenomenon applies to humans is not known.  I personally suspect it does, and if so several years of increased male human fertility could be involved.  As my readers know, I am concerned both with normal human longevity and longevity that could possible double or triple our normal life spans.

Aging and Testosterone in men

One of the theories of aging covered in my Anti-Aging Firewalls treatise is decline of hormone levels with age.  Testosterone level declines in men with age as do levels of other hormones.  I ran across a blog entry this week that provides a short but concise description of this phenomenon and its varied negative consequences.  As readers of my treatise will recall, the central elements of my firewall against age-related declines in hormone levels is supplementation with “mother” hormones which the body converts into various “daughter” hormones including testosterone.  The two central “mother” hormone supplements I suggest taking are pregnenalone and DHEA. Many of the other lifestyle and supplement suggestions in the treatise also impact on hormone and testosterone expression.  Regular exercise is an example.  If we are like mice, regular sex may help too.

Getting to living really long

I have Google report to me all news items  on “longevity” on a daily basis.  Each day produces around a dozen new items.  There seems no end to me to things that are reported to increase normal longevity: prayer, clean air, pure water, kindness to others, good friends, good mental attitude, Ayruvadic herbs, meditation, red wine, gogi berries, acai berries, walking, running, pomegranate juice, living on top of a mountain, avoiding prescription drugs and radiation, lots of fish, living in Okinawa, telling jokes, intellectual activities, regular sex, etc. etc.   All of these things might help you and I get to 115 if we also have luck of the genetic draw – but that is about it.  To get to where we can live up to 200, 300 or more years, we need to turn to the unknown, the emerging.  That is, we have to look to the stream of new discoveries in molecular biology and that is where my mind is going.  For example, I want to develop a deeper understanding of the various longevity genes and actions of proteins like AKT which seem to play a role in both stem cell proliferation and programmed cell death.  So, updates to my Anti-Aging Firewalls treatise will likely become more and more technical.  I will report on what I am discovering in the treatise and will occasionally highlight items here in this blog.  Meanwhile as to the conventional wisdom of aging, I have constantly to remind myself that since I want to live to 230 I have to live to 115 first.  That requires I pay a lot of attention during the next 20 years (through age 99 for me) to the conventional wisdom of longevity as well as to the newer longevity regimens I am continuing to evolve.

About Vince Giuliano

Being a follower, connoisseur, and interpreter of longevity research is my latest career. I have been at this part-time for well over a decade, and in 2007 this became my mainline activity. In earlier reincarnations of my career. I was founding dean of a graduate school and a university professor at the State University of New York, a senior consultant working in a variety of fields at Arthur D. Little, Inc., Chief Scientist and C00 of Mirror Systems, a software company, and an international Internet consultant. I got off the ground with one of the earliest PhD's from Harvard in a field later to become known as computer science. Because there was no academic field of computer science at the time, to get through I had to qualify myself in hard sciences, so my studies focused heavily on quantum physics. In various ways I contributed to the Computer Revolution starting in the 1950s and the Internet Revolution starting in the late 1980s. I am now engaged in doing the same for The Longevity Revolution. I have published something like 200 books and papers as well as over 430 substantive.entries in this blog, and have enjoyed various periods of notoriety. If you do a Google search on Vincent E. Giuliano, most if not all of the entries on the first few pages that come up will be ones relating to me. I have a general writings site at and an extensive site of my art at Please note that I have recently changed my mailbox to
