Abstract

Contactin‑1 (CNTN‑1) has been reported to serve an oncogenic role in several cancer types. However, detailed mechanisms describing the influence of CNTN‑1 in prostate cancer progression have not yet been elucidated. The present study aimed to determine the clinical significance of CNTN‑1 expression in prostate cancer progression, and also to investigate the regulatory role of CNTN‑1 in the proliferation, migration and invasive ability of prostate cancer cells. The results of the present study indicated that expression levels of CNTN‑1 were significantly higher in prostate cancer tissues compared with adjacent normal tissues. Moreover, a high expression level of CNTN‑1 was positively correlated with tumor size, stage and metastasis, as well as a poorer prognosis in patients with prostate cancer. Furthermore, CNTN‑1‑knockdown in prostate cancer cells (using short hairpin RNA) resulted in the significant inhibition of cancer cell proliferation, colony formation, migration and invasiveness. Silencing of CNTN‑1 expression also suppressed epithelial‑mesenchymal transition in prostate cancer cells via the upregulation of E‑cadherin, and the downregulation of N‑cadherin and vimentin expression. Inhibition of CNTN‑1 expression also reduced the activity of the PI3K/AKT signaling pathway in prostate cancer cells. Thus, it was demonstrated that CNTN‑1 expression is upregulated, and plays an oncogenic role, in prostate cancer cells. The results of the current study suggest that CNTN‑1 may represent a promising therapeutic target, potentially improving the treatment of patients with prostate cancer.
