Fig. 5From: Effect of hydroxyurea on SP1, LIN28B, IGF2BP3, COL4A5, BCL2, gamma globin genes expression: an in vitro studyEvaluation of COL4A5 gene expression in K562 cells treated with concentrations of 50, 100, and 150 μM HU at three times of 12–24-48 h. The data are presented as a relative expression with the internal control gene GAPDH and repeated three times (ns = non-significant, p = 0.004**, p = 0.0002***, p < 0.0001****)Back to article page
