Towards an Experimental and Systems Biology Framework for Cancer Cell Therapeutics
Petar M. Mitrasinovic.
Since most molecular studies on death of cells in tissues have been carried out on isolated cell populations due
to known difficulties manifested by interactions with surrounding cells, a novel means of investigating general principles
governing cellular functions under oxidative stress conditions is needed in order to shed more light on the background of
cancer disease. It is believed that relevant signal transmission may be discovered by transition from molecular to modular
cell biology. Systems-level kinetic models are thus expected to explain dynamic behavior and go far beyond the static
pictures of the topologies of the signaling pathways. The outline of this review is to feature several representative
problems, based on combined - experimental and systems biology studies over the last few years, with a particular
emphasis both on the elucidation of how cells interpret the same signal stimulation in distinct fashions (cell death vs. cell
survival) and on the identification of signaling molecules with therapeutic relevancy. The origin of oscillations in such
molecular mechanisms under oxidative stress conditions and implications of these oscillatory non-linearities for the
development of successful therapies are discussed.
