Abstract: Objective: To investigate the role of phosphodiesterase 4D in the pathogenesis of oral squamous cell carcinoma (OSCC). Methods: Fifty-three OSCC patients and 5 OSCC cell lines were collected, 55 healthy adults and 2 normal oral epithelial cells were used as the control. The mRNA levels of PDE4D in these samples, the proliferation of SSC25, the migration abilities, and the cell apoptosis were examined by quantitative RT-PCR, CCK-8, wounding healing assay, and flow cytometry as well as western blot, respectively. Results: The levels of PDE4D mRNA in OSCC tissue and cell lines were significant higher than that in normal control group (P<0.01); the levels of PDE4D mRNA in OSCC tissue were positively correlated with the degree of OSCC differentiation (P<0.05); the abilities of cell proliferation and migration were significantly inhibited by Rolipram; Rolipram induced a significant apoptotic changes on SCC25 cells (P<0.05). Conclusion: PDE4D plays an important role in the OSCC pathogenesis.
