Glycomics [Listen Now] The study of
sugars within organisms is becoming one of the most talked about
field in the bio-sciences. Biochemists are finding that these sugars
are as vital as proteins in making each cell work. These sugars
modify proteins and lipids which fine tunes these molecules. These
glycans, glycoproteins and glycolipids, are major components of the
outer surface of mammalian cells. It is becoming more clear that
glycans are fundamental to many biological processes including
fertilization, immune defense, viral replication, parasitic
infection, cell growth, cell-to-cell adhesion and inflammation. It
is not surprising therefore that errors in sugar modification of
proteins and lipids have severe implications and are associated with
common diseases such as cancer and diabetes.
The National
Institute of General Medical Sciences (NIGMS) of the National
Institutes of Health (NIH) has identified glycomics as one of the
key fields that will shape the future of Molecular and Cellular
Biology in this millennium and has decided to fund a Consortium
for Functional Glycomics.
Glycobiology
Journal
Science Magazine, a peer-reviewed journal of
the American Association for the Advancement of Science (AAAS),
devoted its 23 March 2001, Volume 291, Issue 5512 to carbohydrates
and glycobiology.
Recognizing the importance of sugars in
health and disease, increasing numbers of researchers in academia
and the biotechnology industry have recently stepped up efforts to
learn the details of their structures and activities and to
translate those findings into new therapeutic agents. Read
Physicians
were also slow to realize the importance of sugars to human health.
They now know that a variety of birth defects, potentially fatal
syndromes, and other illnesses stem from problems with sugars. Read
You may
think of sugars as simple substances you use to sweeten your coffee.
But simple sugars can be built into giant molecules called complex
sugars that rival DNA and proteins in size and complexity. Until
recently, biologists thought that living things used them either
mainly for storing energy, as a structural material (in the form of
cellulose, for example) or perhaps as mere decorations on the
surfaces of cells. But now it has become clear that these molecules
are far more than just the icing on the cake. Read
Journal Acta Anatomica Features Glycosciences
The prestigious International Journal of Anatomy, Embryology
and Cell Biology devoted an entire issue of their publication Acta
Anatomica Vol.161, No. 1-4, 1998 publication to the topic of the
glycosciences.
The editor's note referred to the impressive
progress made in recent years in glycoconjugate research alluding to
the fact that it has left footprints in virtually all fields of
biology and medicine, not only in immunology, but also in general
cell biology, developmental and reproductive biology and
neurobiology. He continued by commenting many of "the secrets of
glycosciences are only accessible to a closed circle of aficionados"
who appear to be the only ones to understand the 'meaningful words
of a sweet language of life'.
The back cover of this
publication states that the last decade has witnessed the rapid
emergence of the concept of the sugar code of biological
information... Indeed, monosaccharides represent an alphabet of
biological information similar to amino acids and nucleic acids, but
with unsurpassed coding capacity.
Acta Anatomica is
published by Karger Medical and Scientific Publishers.
