Engines of longevity research

Powerful behind-the-scenes engines are increasing the scientific knowledge base related to longevity at an ever-increasing pace. For example, the following bulleted items are drawn from articles in the February 1, 2009 issue of GEN: Genetic Engineering and Biotechnology News, a biotechnology industry trade magazine.

One set of engines is to be found in the field of drug discovery.

  • Research in RNAi (RNA interference) mechanisms, drugs and therapies, approaches that interfere with the role of RNA, the complement of DNA in the cell cycle. RNAi therapies work through selectively silencing genes, effectively interfering with entire gene-activation pathways, and are under development for a number of diseases. This research is forwarding our knowledge of cell cycle and gene activation path basics and the roles of micro RNAs in the human genome – key issues insofar as longevity is concerned.
  • Epigenomics is of increasing importance as a research tool – the area that goes beyond genetics to look at what is going in the cell nucleus the DNA and RNA to determine characteristics of organisms and explain the vast complexity of what is going on in the biological world. Genes are located on chromosomes with large sequences of DNA separating them. Once this was called “junk DNA” and ignored, but we now know that junk contains secrets essential for life. Not only is there important information and variations in the genes and their variations (polymorphisms) but also in the rest of the DNA, and also in the RNA. Decoding the human genome was just the tip if the iceberg. Much of this basic research is also driven by the quest for drug discovery, looking for ways to interfere with cancer proliferation for example. Meanwhile, this research is starting to tell us more about how we are put together at the most basic level and what might help us live longer.

Another set of engines accelerating the rate of knowledge discovery is rapid and relentless underlying improvements in the tools for genetic and biotechnology research and engineering, the tools that make the above kinds of life-science research possible. There is constant improvement in capacity along with cost decrease of gene microarray chips, chips that allow simultaneous screening for hundreds or thousands of genes. There seems to be a version of Moore’s Law operating here. Moore’s Law says the capacity, power and cost-effectiveness of microprocessors doubles every 12-18 months, and that law that has consistently operated during the last 30 years. The same nature of increase in cost effectiveness is also true for gene sequencers. I can imagine going into Wallgreens or CVS, paying $14.99, spitting on a chip and getting back a printed and on-line profile checking 1500 of my genes for susceptibility to diseases. This could happen in 10 years, perhaps less. But there are many other improvements in bioresearch technology going on right now as well. For example:

· A new bioreactor design allows for the 3-D cultivation of cells, important to mimic the 3-D conditions in actual organisms.

· New molecular visualization technologies are allowing mapping of vascular cell surfaces in normal and pathological organs, mapping the locations of proteins and identifying key chemical biomarkers.

· New technologies are now available for visualizing signal transduction pathways and protein-protein interactions within a single cell, transcending the limits of Western Blotting, a traditional laboratory workhorse technique. Of course, the central issue for the more advanced theories of aging is further understanding critical cell signaling pathways.

Every month, GEN reports on developments similar to the above, so this is just a small sampler of the engines powering our increasing understanding of longevity.

About Vince Giuliano

Being a follower, connoisseur, and interpreter of longevity research is my latest career, since 2007. I believe I am unique among the researchers and writers in the aging sciences community in one critical respect. That is, I personally practice the anti-aging interventions that I preach and that has kept me healthy, young, active and highly involved at my age, now 93. I am as productive as I was at age 45. I don’t know of anybody else active in that community in my age bracket. In particular, I have focused on the importance of controlling chronic inflammation for healthy aging, and have written a number of articles on that subject in this blog. In 2014, I created a dietary supplement to further this objective. In 2019, two family colleagues and I started up Synergy Bioherbals, a dietary supplement company that is now selling this product. In earlier reincarnations of my career. I was Founding Dean of a graduate school and a full 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 www.vincegiuliano.com and an extensive site of my art at www.giulianoart.com. Please note that I have recently changed my mailbox to vegiuliano@agingsciences.com.
