Effect of TIEG1 on apoptosis and expression of Bcl-2/Bax and Pten in leukemic cell lines
We examined the effect of transforming growth factor-b inducible early gene-1 (TIEG1) on the apoptosis of leukemic cell lines and expression of B-cell lymphoma 2 (Bcl-2) and phosphatase and tensin homolog (Pten). Four leukemic cell lines (HL-60, U937, Raji, and K562) were treated with 0, 1, 5, 10, and 20 ng/mL TIEG1, respectively. The cell growth inhibitory ratio was assessed using the MTT assay. An inhibitory curve was drawn, and half-maximal inhibitory concentration was calculated.
