Selective Cytotoxicity of UA to tumorigenic MCF-7 over non tumorigenic MCF 10A.

<p>Percentage growth inhibition and IC₅₀ of UA in different breast cancer cell lines. MCF-7 and MCF 10A cells were treated with either doses of 2.5, 5 and 10μM UA or Doxorubicin for 48 hours and cytotoxicity was assessed by SRB assay. Columns, average of triplicate readings of samples; error bars, ± S.D. <b>C.</b> Phase-contrast photomicrograph of MCF-7 and MCF 10A cells treated with either vehicle control or different doses of UA.
