Those are all just studies showing some perturbation of non-clinical laboratory systems. You can find the same sorts of stuff on pomegranate juice and garlic (or just about anything that you care to think about, e.g. see below).
The proof of the pudding is that they treated 800 patients and got 2 (two) CRs and both of those patients got real chemotherapy, in addition to DCA and that DCA only produces "benefits" in patients who also receive real chemotherapy.
That's the track record of every quack remedy which gets promoted for cancer use. It wasn't a quack remedy until they treated their first 25 patients, but it's certainly a quack remedy after they've treated 800 and only got what they now admit that they got.

This paper suggests that not only does DCA not work very well, it also has the ability to antagonize the activity of real chemotherapy drugs which do work.

The conclusion remains the same. The drug is a dud.
