Immunoblotting assay further identified that the Wnt5a-inhibited apoptosis and GF109203X-mediated increase of apoptosis were associated with a decreased and an increased expression of proapoptotic proteins of Bax, caspase 3, and apoptosis inducing factor (AIF) in lung cancer cells, respectively (Figure 8). This evidence concerns the gene WNT5A and lung carcinoma.
