Effects of WSPM, LaCl₃, CeCl₃, NdCl₃ and NaF on the A549 cell cycle regulator mRNA expression. The abscissa represents the blank control, 2 mM of LaCl₃, 2 mM of CeCl₃, 2 mM of NdCl₃, 2 mM of NaF, 200 µg/ml of WSPM2.5, and 200 µg/ml of WSPM10, from left to right, respectively, and the ordinate represents the relative expression quantity of the corresponding genes. A549 cells were treated with the above substances for 24 h, and the expression of 14 kinds of cell cycle regulators were measured by qRT-PCR. *Compared with the blank group, P < 0.05; **Compared with the blank group, P < 0.01
