[TOKYO] A workshop planned for next month on the
genetics and neurology of apes could pave the way to a better understanding of
the relationship between the human genome and the brain, its organizers say. The Genes and Minds Initiative (GEMINI) workshop will try to improve
coordination of existing ape-genome sequencing efforts and of related research
in neurological gene expression and gene-based evolutionary study of apes. It
could also serve as a springboard for a major international effort in the
sequencing of ape genomes. The meeting is being jointly organized by the National Institute of Genetics
(NIG) and the Institute of Physical and Chemical Research (RIKEN) in Japan, and
will take place in Tokyo. "The aim is to provide a place to discuss
possible international and interdisciplinary cooperation on understanding what
makes us human," says Yoshiyuki Sakaki of RIKEN's Genomic Sciences Center.
Close relative: as ape genomes are similar to our own, comparative
analysis could pay dividends. Sakaki and Lehrach hope to use the experience they gained sequencing
chromosomes 21 and 22 for the human genome project in assembling ape genomes.
Because of the great similarity, Lehrach thinks that they will be able to
assemble many of the corresponding ape DNA fragments right on top of the human
sequence. "This could reduce sequencing needs and make it a very cheap
project, perhaps costing less than US $100 million," says Lehrach. Last year, RIKEN announced a project to compare chimpanzee and human genomic
sequences, but commitment to the human genome and lack of funding have held back
its progress (see Nature
406, 4; 2000). Now the NIG is involved, details of the plan are being
firmed up — although funding is still elusive. RIKEN's Brain Science Institute will provide the project with candidate
genes, such as those related to language and brain development, from human brain
research projects. These will be used to correlate genes to their function in
the brain, using microarrays. RIKEN's Genomic Sciences Center is expected to handle sequencing and initial
analysis, starting with the chimpanzee equivalent of chromosome 21 and other
genes suggested by the Brain Science Institute. The NIG will run a comparative
study of chimpanzees, orang-utans, macaques and gorillas in an attempt to
determine the way in which the various different species have evolved. So far money for the project has not been forthcoming, with each group using
funds from some of their other projects to allow the to do the planning. But
Naruya Saito, a geneticist at the NIG, hopes that Japan is poised to take the
leading role in an international ape sequencing project. He sees it as an
opportunity for Japan to "show the world its sequencing capacity". The project is also notable because it marks the first collaboration between
two of Japan's premier research institutes under the auspices of the newly
formed Ministry of Education, Culture, Sports, Science and Technology (see Nature
408, 757; 2000). In the past, rivalry between the various agencies
has made such a collaboration difficult. Gemini — the astrological sign of the
twins — could therefore represent not only the relationship of genes and the
mind, says Saito, but also a new match-up between the NIG and RIKEN.
The ape genome is thought to be around 99% equivalent to the human genome.
"By examining the subtle genetic differences relating to the nervous system
and brain function, it will be possible to shed light on language, the ageing
process, and on sensitivity to disease," says Hans Lehrach of the Max
Planck Institute for Molecular Genetics in Berlin. For example, researchers
might be able to establish what makes apes resistant to Alzheimer's disease and
AIDS.
