Abstract

Objective: To study the role of cyclin D1 in regulating the biological behavior of head and neck cancer. Design: Squamous cell carcinoma of the head and neck (SCCHN) cells were stably transfected with an anti-sense cyclin D1 using lipofectin-mediated transfection. In vitro growth assays, cell cycle analyses, cytotoxicity assays, and in vivo tumorigenicity assays were performed. Materials: Human SCCHN cell lines TU138, TU167, TU177, TU182, MDA1831 and MDA1386 and athymic nude mice were used for this study. Results: The antisense cyclin D1 transfected cells revealed decreased growth rates in vitro and decreased tumorigenicity in athymic nude mice. Furthermore, anti-sense cyclin D1 transfection enhanced the chemosensitivity against cisplatin. Conclusions: These studies provided evidence that over-expression of cyclin D1 may play art important role in growth rates and biological behavior of human head and neck cancer. Additionally, expression of cyclin D1 may make human head and neck cancer cells resistant to platinum-based chemotherapeutic approaches. The ability to Suppress the malignant phenotype by down-regulating cyclin D1 expression may provide a new gene therapy approach for patients with head and neck cancer.
