One of the most conserved features
of all cancers is a profound reprogramming of cellular metabolism, favoring
biosynthetic processes and limiting catalytic processes. With the acquired
knowledge of some of these important changes, we have designed a combination
therapy in order to force cancer cells to use a particular metabolic pathway
that ultimately results in the accumulation of toxic products. This innovative
approach consists of blocking lipid synthesis, at the same time that we force
the cell, through the inhibition of AMP-activated kinase, to accumulate toxic
intermediates, such as malonyl-coenzyme A (malonyl-CoA) or nicotinamide adenine
dinucleotide phosphate. This results in excess of oxidative stress and cancer
cell death. Our new therapeutic strategy, based on the manipulation of metabolic
pathways, will certainly set up the basis for new upcoming studies defining a
new paradigm of cancer treatment.
