We have previously reported that PPP treatment induced moderate tolerance in two out of 10 cell lines only, and here report the acquired genomic and expression alterations associated with PPP selection over 1.5 years of treatment. %U http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0014757
