Home > Press > Senesco Expands on Preclinical Multiple Myeloma Findings

Abstract:
Senesco Technologies, Inc. ("Senesco" or the "Company") (Amex: SNT) announced today
further details of its continuing preclinical multiple myeloma research. In
February 2008, the Company announced results of preclinical animal studies in
which Senesco's Factor 5A technology, encapsulated in nanoparticles, was able
to induce apoptosis in multiple myeloma tumors when injected intratumorally.

Senesco Expands on Preclinical Multiple Myeloma Findings

NEW BRUNSWICK, NJ | Posted on June 5th, 2008

Senesco has continued its research in both preclinical animal models and
human multiple myeloma cell lines, while also studying intravenous delivery of
its therapy. In its previously announced preclinical testing and its recent
expanded studies, the Company has used a combination therapy of its siRNA
against Factor 5A, as well as a plasmid of the Factor 5A gene encapsulated in
a nanoparticle.

Whether the combination therapy was injected intratumorally or
systemically, human multiple myeloma tumors grown subcutaneously in the flanks
of immunodeficient mice were reduced by approximately 95% versus tumors in
untreated mice. Additionally, groups of treated mice were studied for up to
three weeks after the last therapeutic injection and in mice whose tumors had
regressed, the tumors did not regenerate.

In human multiple myeloma cell line studies, Senesco determined that its
siRNA may sensitize cells for apoptosis through a reduction in activation of
NFkB, a key inflammatory transcription factor. The siRNA also reduced levels
of ICAM (intracellular adhesion molecule), a binding molecule, which is
involved in promoting tissue inflammation.

The Company, together with its clinical research organization, is
evaluating potential manufacturing centers for its materials, planning
preclinical toxicology studies and continuing preclinical disease model
studies.

About Senesco Technologies, Inc.
Senesco Technologies, Inc. is a U.S. biotechnology company, headquartered
in New Brunswick, NJ. Senesco has initiated preclinical research to trigger or
delay cell death in mammals (apoptosis) to determine if the technology is
applicable in human medicine. Accelerating apoptosis may have applications to
development of cancer treatments. Delaying apoptosis may have applications to
certain inflammatory and ischemic diseases. Senesco takes its name from the
scientific term for the aging of plant cells: senescence. Delaying cell
breakdown in plants extends freshness after harvesting, while increasing crop
yields, plant size and resistance to environmental stress. The Company
believes that its technology can be used to develop superior strains of crops
without any modification other than delaying natural plant senescence.
Senesco has partnered with leading-edge companies engaged in agricultural
biotechnology and earns research and development fees for applying its
gene-regulating platform technology to enhance its partners' products.
