WebbThirty five genes were upregulated and 15 genes downregulated at least 2-fold by As(2)O(3) in U87-MG cells; whereas, 38 genes were upregulated and 21 genes downregulated at least 2-fold in T98G cells by As(2)O(3). After As(2)O(3) treatment, p53 expression was upregulated 56.5-fold in T98G cells, but only 6.0-fold in U87MG cells.
