Bryant
Villeponteau, Ph.D. is Senior Vice President of R&D at
Genescient and Chairman and Chief Scientific Officer at
Centagen.
Genescient’s focus is to extend healthy human lifespan by using
advanced genomics
to develop therapeutic substances that attack the diseases of aging. It
is the first company founded to exploit artificial selection of animal
models for longevity.
Its extremely long-lived animal models (Drosophila melanogaster)
have
been developed over 700 generations. They are an ideal system for the
study of aging and age-related disease because Drosophila
metabolic
genetic pathways that are highly conserved in humans.
Their sophisticated analysis cross-links gene function in Drosophila
with
their human orthologs, thus revealing targets for therapeutic
substance development. To date Genescient has discovered over 100 of
these genomic targets, all related to the primary diseases of aging.
This large library of targets, enables Genescient to effectively select
and test therapeutic drug candidates. To date, Genescient’s
“proof-of-concept” testing program has yielded a number of very
promising therapeutic substances.
