Abstract

Tumor development and progression are multistep processes that involve local tumor growth and invasion, followed by metastasis. The aggressiveness of the tumor is the major determinant of the mortality of oral cancer patients. The present study investigates whether the expression levels of cyclooxygenase‑2 (COX‑2), nuclear factor‑κB (NF‑κB), peroxiredoxin 1 (PRDX1) and PRDX6 are associated with the development, proliferation, differentiation and recurrence of oral squamous cell carcinoma (OSCC). The mRNA expression levels of COX‑2, NF‑κB, PRDX1 and PRDX6 were examined in 50 OSCC specimens and 19 normal oral mucosae by quantitative polymerase chain reaction (qPCR). qPCR analysis showed that the mRNA levels of COX‑2 in OSCC were significantly higher than those in the normal oral mucosae (P=0.021). The expression levels of PRDX1 in high‑stage tumors (T3 and T4) were significantly elevated compared with those in low‑stage tumors (T1) (P=0.047). Additionally, the expression levels of NF‑κB in the high‑grade tumor were significantly elevated compared with those in the low‑grade tumors (P=0.030). Overall, it was indicated that the expression of COX‑2 is strongly associated with the development of OSCC. Moreover, the enhanced expression of PRDX1 and NF‑κB may function in the progression of OSCC, which serves as a useful marker for prognosis in patients with oral cancer.
