Poly-L-Arginine Induces Apoptosis of NCI-H292 Cells via ERK1/2 Signaling Pathway
Figure 3
Expression of p-ERK/ERK in NCI-H292 cells. (a) Protein expression bands were detected by western blot. (b) The bar chart shows the ratio of p-ERK/ERK. Compared with the control group, phosphorylation of ERK1/2 increased significantly in groups treated with PLA, especially at a PLA concentration of 20 mg/l. .
