This year marks the 50th anniversary of
one of the most important discoveries of modern
science, the double
helix structure of DNA. Since 1953, DNA research
has had an impact on everything from biology,
agriculture and medicine
to criminal law and justice, art and politics.
At UC Davis, one of the nation's leading research
universities in biological
sciences, a wide range of experts are available
to discuss the significance of Watson and Crick's
discovery; current
research in DNA; and what the future may hold.
Center for Genomics at UC Davis
The Genome
and Biomedical Sciences Facility, a $90 million building currently under construction at UC Davis, will house the UC Davis Center
for Genomics and other research groups in biomedical sciences. Leading the center is associate director Craig
Benham, an expert in DNA structure and bioinformatics. Working out the
information content of genome sequences and how their genes are regulated
together are the next challenges in genomic science, he said. Benham, who
also has appointments in the departments of of mathematics and biomedical
engineering, is a mathematician who studies how the structure of DNA and
stresses on the molecule can affect gene function. Before joining UC Davis,
he was a professor of biomathematical sciences at the Mount Sinai School
of Medicine in New York. Contact: Craig Benham, Biomedical Engineering, (530)

Genomics technology
UC Davis researchers have access to DNA sequencing technology
and services through facilities such as the Division of Biological Sciences' DNA
Sequencing Facility and the College
of Agricultural and Environmental Sciences' Genomics Facility. The college's
facility also provides access to robotics equipment for high-throughput tasks.

Plant and animal genomes
As a leading center for research in biology, veterinary medicine, agricultural and environmental sciences, it's not surprising that UC Davis faculty are studying the genetics and genomics of an unusually wide range of plants and animals.

Mouse Biology Program
The laboratory mouse is the preeminent model for human
and animal genomics research. Mice are well defined genetically and their genome
can be precisely manipulated, allowing researchers to breed mice with specific
genetic qualities. The UC
Davis Mouse Biology Program, based at the Center for Comparative Medicine,
provides a valuable scientific resource for the biomedical research community,
including teaching and training opportunities, mouse molecular genetics and
embryo manipulation services, and research to develop new technologies. These
resources are available to researchers at UC Davis, and regionally, nationally
and internationally. More information: mbp@ucdavis.edu.

Diet, genes and 'nutrigenomics'
Diet can be a serious risk factor for a number of diseases,
such as Type 2 diabetes, obesity, heart disease and some cancers, but the exact
effect of different components of food may depend on your individual genetic
makeup. For example, a single letter change in DNA in people living in Scandinavia
10,000 years ago allows most Caucasian adults today to drink milk without getting
sick due to lactose intolerance. The new National
Center of Excellence in Nutritional Genomics, a joint venture between UC Davis and the Children's Hospital Oakland
Research Institute (CHORI), aims to identify genes controlled by naturally
occurring chemicals in food and study how these genes can tip the balance between
health and disease. The center, directed by Raymond
Rodriguez, professor of
molecular and cellular biology at UC Davis, is supported by a five-year, $6.5
million grant from the National Center on Minority Health and Health Disparities,
a division of the National Institutes of Health.

Obesity and genetics
Craig
Warden, associate professor of neurobiology, physiology and behavior
and of pediatrics at UC Davis, identifies genes linked to obesity in mice
and searches for their human counterparts using databases of the human genome
and comparison to humans with common single nucleotide polymorphisms (SNPs).
A number of genes linked to obesity have been found by researchers at UC
Davis and elsewhere, including uncoupling protein 2 (UCP-2). Common natural
alleles (variants) of UCP-2 have been consistently associated with obesity,
making this the best example so far of a gene known to influence a significant
proportion of human obesity, Warden said. Researchers can insert the DNA
for these genes into mice to study their effects. Overall, it's still difficult
to estimate how much genetics contributes to conditions such as obesity,
diabetes and high cholesterol, Warden said. Contact: Craig Warden, Rowe Program
