Judy Campisi Shares Her Thoughts about Aging in Scientific American


Judith Campisi, professor at the Buck Institute for Research on Aging and senior scientist at the Lawrence Berkeley National Laboratory

One of the questions in the Scientific American interview of one of the top gerontologists, Judy Campisi, is really intriguing. Here’s the question and Dr. Campisi’s answer:

What would you say is one of the biggest mysteries of aging research?
Why do organisms with remarkable genetic similarity have sometimes remarkable differences in life span?

We know that for the most part, many of the processes that go on in the human body also go on in yeast and mice. Yet, yeast live a few days, a mouse lives about three years, and people live for decades. We really do not know what evolution has done to take basically the same genes and produce different life spans.

I think this is probably the most important question in aging research, because answering it may lead to those mysteries, and subsequently, clues to the problem of aging that we are now missing. What are those odd lifespans/metabolic patters/gene expression profiles/regenerative capabilities that certain animals have, but others don’t? What is that scientists dream of investigating, but can’t because of lack of funding and low chances of getting funds for such unconventional studies?

What mysteries of aging do you know?

    Really what Ms Campisi is talking about is understanding metabolism and that’s not going to be accomplished in her lifetime. This is curiosity based science which is important but it’s not the most important thing. The most important is to understand how we can apply the knowledge we have to repair damage metabolism causes.
