I'll throw my 2 cents in here. I am pleased with what I consider to be aggressive pr on managements part. If they don't release p21 results - they will still keep pushing every tangible piece of data they can. It is possible, given the Roche/Nutlin fiasco - they they will withhold all p53 activation results until they have confirmed, in living humans, that Kevetrin doesn't harm the p53 activity in healthy cells. Also - much p53 research over the years has shown that activation can lead to protection of all cells, both healthy and cancerous. Again - this may create some caution on their part and I would not think negatively about them at all if these outliers were a consideration.
