I don't know, I would like to hear numbers of how big a sample they tested. There are a a lot of "MAY" and "MIGHT" in that article.
It's a preliminary article, and it by definition will have a lot of "may" and "might". All they are talking about at this point is action in the test tube. This isn't a puff piece by NORMAL (pun intended), but a serious report of lab research, published so others can try to replicate. As you know, this is the scientific method.....formulate a hypothesis, test it, draw conclusions, and publish so the scientific community can do replication and extension work. However, with that in mind, I think this is an exciting piece of research, as lung cancer has proven to be one of the most resistant to contemporary therapies.
