Objective:
To study the expression and correlation of eIF4E and VEGF in laryngeal squamous cell carcinoma (LSCC).
Method:
Western-blot analysis was performed on tumor core,transition core, "tumor-free" core of 20 specimens of fresh LSCC by using anti-eIF4E and VEGF antiserums.
Result:
The expression of eIF4E protein level from "tumor-free" core, transition core and tumor core of LSCC appeared progressive overexpression. It appeared that there was significant elevation of VEGF protein level in tumor core compared with tumor transition and "tumor-free" core. There appeared to be statistically significantly correlation of eIF4E and VEGF expression.
Conclusion:
Overexpression of eIF4E may be a molecular marker of malignant transformation and progression. The overexpression of VEGF is highly associated with the growth and metastasis of LSCC, and may be of prognostic value. The correlation of eIF4E and VEGF may serve as a potential target for antiangiogenic therapy of LSCC.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
