Comparison of content of m⁵C in DNA from tissue and blood.

<p>5-methylcytosine content (R) in DNA from 183 patients with brain tumors: cancer tissues (upper panel) and blood (bottoms panel). The figure clearly shows that m⁵C content, expressed as R [ = (m5dC/m5dC+dC+dT)×100] coefficient, in DNA from tumor tissue matches the results from blood <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0092599#pone.0092599-Barciszewska2" target="_blank">[25]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0092599#pone.0092599-Barciszewska3" target="_blank">[26]</a>.
