Because it is so efficient, RNA interference represents a true revolution in many domains, and it is also true for cancer. I am confident that RNA interference will

facilitate the design of new cancer therapies and this is for two reasons. First, because it allows to explore all the pathways that are deregulated in cancer cells, and thus discover new targets. And second, because it might be used to inhibit specifically noxious genes that are required for cancer cell survival. For example, this slide summarizes what we know on colon cancer.

To go from a normal tissue to a cancer able to invade other tissues and create metastasis takes many different steps, and involves a number of various genes and pathways that more or less control cell fate. And this does not take into account the fact that cancers are heterogeneous, and even for a given cancer type there is a very high level of variability between patients. Let's review very briefly what we know about oncogenesis. It all begins with the regulation of the balance between cell proliferation and differentiation. For example, in the skin the population of precursor cells proliferates,
