Abstract

In order to identify the anti-invasive and anti-metastatic effect of the synthetic retinoid N-(4-hydroxyphenyl) retinamide (4-HPR) on the human bladder cancer EJ cell line, and to study its impact on the expression of wingless-type mouse mammary tumor virus integration site family, member 5a (Wnt5a), the phosphorylation of c‑Jun N‑terminal kinase (JNK), the expression levels of matrix metalloproteinase-2 (MMP-2), and the migration and invasion of EJ cells, migration and Matrigel invasion assays, as well as western blot analyses, were used in the present study. The results of the migration and Matrigel invasion assays indicated that the inhibitor of JNK SP600125 could inhibit the effect of 4‑HPR on EJ cells. The expression of Wnt5a and MMP‑2, and the phosphorylation of JNK, were analyzed by western blotting. The data revealed that 4-HPR inhibited the migration and invasion of bladder cancer cells through stimulating Wnt5a activation, causing the downregulation of MMP‑2 expression and enhancing the phosphorylation of JNK in these cells. However, JNK signaling did not appear to have a direct effect on the expression of MMP‑2. The present study demonstrated that 4‑HPR may be a potent anti‑invasive and anti‑metastatic agent that functions via the Wnt5a/JNK and Wnt5a/MMP-2 signaling pathways.
