The International Milk Genomics Research Project: Online Course
J. Bruce German - UC Davis
The promise of a revolution in life science knowledge, research and
applications is now ongoing. The generation of students being educated
must emerge with a clear understanding not only of what genomics is but
what genomics means to each of their respective disciplines. As a
practical consequence, learning genomics will be best accomplished by
orienting the principles and applications directly to the students’
choice of career path.
For students studying human genomics and pursuing careers in
pharmacology and applied medicine, or alternatively studying bacterial
genomics and pursuing careers in bacteriology, the course materials are
in place and relevent to these fields. However for students pursuing
careers in nutrition and food science, there are not suitable course
materials and relevant examples currently available. This lack of
resources provides an unusual opportunity for the Milk Genomics Project
to step forward and establish a course program in the area of Genomics
and Nutrition and Food, using the milk genome as the basis for
illustrative examples.
The milk literature already contains examples of modern genomic
science. The gene sequences, chromosomal mapping, regulatory sequences
and transcriptional processing sequences are known for the caseins and
several other important milk genes as a result of decades of research
into their respective proteins. These genes are present and well
annotated on the major databases of sequence structure and function
(SwissProt etc,) readily available using consensus tools (BLAST etc.)
and known across a variety of comparative mammalian species. The
relationships between sequence, structure and various functions have
been developed for several milk proteins (lactoferrin,
beta-lactoglobulin) and again fully annotated in the major databases.
In fact, beta-lactoglobulin has served as a sequence structure function
model for the identification of an entire eukaryotic gene family
(FABP). The milk genome is large enough to provide a statistically
valid database suitable for bioinformatic analyses, but small enough to
allow comparisons to more traditional analysis and imaging protocols.
The milk genome is composed of highly relevant and biologically
important genes and is presumably largely devoid of the redundant,
nonfunctional or silenced genes that represent a substantial fraction
of entire eukaryotic genomes including the human.
Students now must acquire the knowledge of genomics as the basis of
their entire future careers in biology. The speed that they become
proficient at using genomics will depend on how relevant their course
material is to their chosen career path. The genes of milk represent
the ideal biological model for the discovery process of genomics for
students embarking on careers in food, nutrition and related academic
and industrial positions.
