Poly-L-Arginine Induces Apoptosis of NCI-H292 Cells via ERK1/2 Signaling Pathway
Figure 4
Expression of Bax, Bcl-2, and caspase-3 in NCI-H292 cells. (a) Protein expression bands were detected by western blot. (b) The bar charts of Bax/β-actin and Bcl-2/β-actin. (c) The bar chart shows the ratio of Bcl-2/Bax. (d) Expression of caspase-3 normalized to β-actin. Compared with the control group, the expression of Bcl-2/Bax decreased and cleaved caspase-3 increased. , , , and .
