Gary,
In my reading of the reports on the Penn State research - the compound that is derived from fish oil is, in fact, a metabolite of fish oil. In other words, our bodies make this compound during the fish oil metabolism process and so eating Fish Oil will put this compound into your body. What is unique and apparently "patentable", is the pharmaceutical manufacture of the metabolite in large quantity that would be needed in order to combat CML. It works in mice apparently.
Like many mouse models - way too early to tell, but it is exciting that focus in CML research is moving towards the stem cells and their eradication.
I only just started taking Fish oil omega-3 to help in the bio-absorption of Curcumin. Who knows - maybe it will have a synergistic affect.
