Abstract

The present study aimed to investigate the expression and roles of deleted in pancreatic carcinoma locus 4 (DPC4) and vascular endothelial growth factor (VEGF) in the development of cervical carcinoma. A total of 115 patients aged between 25 and 60 years were involved, including 19 cervical inflammation, 35 cervical intraepithelial neoplasia (CIN), and 61 cervical squamous‑cell carcinoma (CSCC). The protein expression rates of DPC4 and VEGF in all samples were detected using immunohistochemistry. The protein levels of DPC4 and VEGF in CSCC samples were measured using ELISA. Microvessel density (MVD) of each CSCC sample was measured according to the Winder method. Association analysis between DPC4, VEGF and thrombospondin‑1 (TSP‑1) was conducted using Spearman's correlations. The negative expression rate of DPC4 [DPC4 (‑)] and positive expression rate of VEGF [VEGF (+)] of the CSCC group were significantly higher compared with that in the cervical inflammation and CIN groups (P<0.05). In the CSCC group, the protein level of DPC4 decreased, while the VEGF level increased significantly compared with the healthy control group (P<0.05). The MVD in the DPC4 (‑), VEGF (+) and TSP‑1 (‑) groups was significantly increased compared with that of the DPC4 (+), VEGF (‑), and TSP‑1 (+) groups (P<0.05). The expression of DPC4 was negatively associated with VEGF and TSP‑1 (P<0.01). These results suggest that DPC4, VEGF and TSP‑1 are involved in the carcinogenesis of cervical carcinoma by inducing angiogenesis. In addition, the loss of DPC4 induces angiogenesis through increasing VEGF. Thus, VEGF may be a target gene regulated by DPC4.
