Prostaglandin is a product of cyclooxygenase-2. Compelling
epidemiological and experimental studies over the last few decades have
suggested that elevated cyclooxygenase-2 activity has been associated
with enhanced development and spread of colorectal cancer, although the
exact mechanisms of action are largely unknown or poorly understood.
Modulation of adhesion molecules allows colorectal cancer cells to break
away from their primary site and invade into the extracellular matrix:
the initial process of metastasis. Other molecules such as
Metalloproteinases, Cluster differentiation 44 and selectins are also
thought to be involved. This short book revisits these various processes
of cancer metastasis and reviews possible mechanisms of action with
cyclooxygenase on a molecular level. Furthermore, common intrinsic and
extrinsic modulators of cyclooxygenase are also discussed. This
important biological concept has potential pharmacological implications
with regards to chemo-prevention of cancer metastasis - remains to be
the leading cause of colorectal cancer deaths.
