Modulation of MGMT expression by 5-Aza.

<p>A) Densitometric analysis of the effect of 5-Aza for each cell line showing relative expression of MGMT compared with beta-actin under each experimental condition. Western blot analysis of MGMT expression after 5-Aza exposure in tumor cell lines. Beta-actin expression was used as a control. B) Relative growth rates of tumor cell lines before and after 5-Aza exposure. B: basal cells, 5Aza: cell line treated with 5-Aza. All data represent the mean value ± SD of triplicate cultures.
