Researchers Find Telomerase Enzyme Can Shield Mice Against a Cirrhosis

The Wall Street Journal Interactive Edition -- February 18, 2000
By LAURA JOHANNES / THE WALL STREET JOURNAL

BOSTON -- Researchers at Dana-Farber Cancer Institute found that an
enzyme that repairs tiny cellular clocks called telomeres can protect
mice against liver cirrhosis.

The paper, published in Friday's issue of the journal Science, is the
most dramatic demonstration to date that boosting cellular levels of
the enzyme, called telomerase, may be useful in treating disease.
Previously, interest in telomerase and telomeres has focused on the
notion that they could somehow be used to lengthen life spans
generally.

Although that hope has so far proven elusive,the cirrhosis news is
likely to heighten the interest of biotechnology companies in
finding telomerase-boosting drugs for a wide variety of conditions.

Already, a handful of companies, including Geron Corp., Menlo Park,
Calif., have active telomerase research programs.

"Cirrhosis is one of several disorders, including multiple sclerosis
and AIDS, where cells lose their ability to regenerate," says Jerry
Shay, a professor of cell biology at the Univ of Texas Southwestern
Medical Center. "Telomerase may be able to restore that ability."

Telomeres, or "end parts" in Greek, are protective caps on the ends
of chromosomes, the gene-bearing cellular structures. Some of the
most intriguing and mysterious parts of the cell, telomeres appear
to get shorter with each generation of cell division. What they do
has been a source of controversy, but some scientists believe they
serve as little fuses that tell cells when to stop reproducing
themselves.

Cirrhosis is a fatal condition often related to hepatitis or
alcoholism in which the liver, the organ that removes toxins from
the blood, stops working properly. After continued destruction,
"liver cells run out of telomeres and lose their ability to
regenerate," says Dr. Ron DePinho, a researcher at Dana-Farber.

The Dana-Farber researchers, working with colleagues at the Albert
Einstein College of Medicine, the Bronx, N.Y., created a strain of
mice with exceptionally short telomeres. Then they attempted to
cause cirrhosis in the mice with various methods, including giving
them a poison that affects the liver and removing two-thirds of
their livers surgically.

The scientists found that the short-telomered mice were dramatically
more likely to develop cirrhosis than normal mice, which are notoriously resistant to the disease. Moreover, when the researchers
used gene therapy to insert telomerase into the cells of the special
strain of short-telomered mice, these mice also proved remarkably
resistant to cirrhosis.

Before telomerase can be tested in humans for cirrhosis, scientists
must figure out how to deliver it into cells and then establish its
safety. Some scientists fear that telomerase therapy, by allowing
cells to divide indefinitely, could spur cancer. But Dr. Shay argues
that so many things contribute to tumor formation that "there is no
reason to say that telomerase alone is going to cause cancer."

It will take at least five to 10 years until telomerase therapy can
be tested in humans for cirrhosis,
but "we're extremely motivated
to move this into the clinic," says Dr. DePinho, who plans more mouse
experiments to confirm the discovery.

"A Stock For the Ages"

George - I've never run across a company like Geron.
Usually companies have bits and pieces here and there
regarding having a solution to a problem or market
need, if we can talk in generic terms here. Or if
they have acheived vertical integration, like the
old Ford River Rouge plant where raw materials
entered one end, and complete cars exited the other,
the company was a huge multi-billion multi-national
corporation with great resources at its disposal.

Geron is a tiny biotech company with maybe 200
people under it's roof (not sure how many people
came with Roselin Institute - but then it was the
nuclear transfer patents that made it so valuable,
as well as the top scientists that made Dolly) and
they own 3 of the key pieces: Telomerase, Nuclear
Transfer, and Stem Cell Research, that for example
would allow them to artificially grow organs, skin,
etc. My understanding of how their science fits
together is they would use their knowledge of
nuclear transfer to transfer your DNA into pluripotent
stem cells, then coax it to differentiate along a
particular path to say skin or heart, etc, and use
telomerase to make the cells grow into the organ
that was needed. While this is still far off into
the future, the thing that's amazing is the future,
as evidenced by the many recent announcements of the
last year and a half, is getting closer at a much
more rapid rate than anyone had envisioned.

As you can see with the news regarding telomerase's
benefical effects on liver cirrhosis of a mouse, the
news just keeps getting better and better, and the
applications more widespread with the passage of time.

I'm just an investor, not a scientist, doctor or a
biochemist, etc. so maybe I'm off the mark here, but I
do think this company will prove itself to be a stock
for the ages.

If you are looking to buy into this company, I would
recommend scaling in any purchase. While a correction
in the Nasdaq is widely anticipated, and especially so
in the biotech area, the sector has been so strong and
the buying so relatively recent that it seems to me,
we would just be pausing here, catching our breath,
before taking up the race again. Plenty of investors
were taken by surprise by the sheer strength of this
run-up, both in this company and in this sector, and
are looking, like yourself to get in or back in.
Whatever you do, be nimble. Buying windows in stocks
overall, with products that address huge potential
markets, are very small now-a-days.

As always, do your own due diligence and never make
decisions based solely on what you read here.
Good luck whatever you decide.

Peter.
