Oridonin increased the phosphorylation of RLC in time and concentration-dependent manner. a, b HeLa cells were incubated with 10 μM oridonin (Ori) for the indicated time before analysis of proteins by Western blotting and densitometric quantification. *P < 0.01 versus control cells (Con). c, d HeLa cells were incubated for 36 h with DMSO and the indicated concentrations of oridonin before analysis of proteins. Data are presented as in d. *P < 0.01 versus Con. e–h A549 cells were treated as in a and c. Data are presented same as in b and d. *P < 0.05 versus Con
