BACKGROUND
Cyclic guanosine monophosphate (cGMP) is an essential second messenger metabolized by phosphodiesterases (PDEs).
OBJECTIVES
We looked for a possible correlation of PDE activities in human oral squamous cell carcinoma (OSCC) with and without lymph node metastases.
MATERIALS AND METHODS
The analysis of phosphodiesterase activity and the cGMP assay were done by reverse-phase HPLC on samples of fresh or frozen gingival tissues. Analysis of cGMP was confirmed with the enzyme-linked immunoabsorption assay.
RESULTS AND CONCLUSIONS
cGMP PDE activity was 34.92 +/- 7.17 SD, 12.89 +/- 4.43 SD, and 35.88 +/- 8.76 SD (nmols/mg of protein), respectively, in controls, samples without lymph node involvement (N-), and specimens with lymph node metastases (N+). cGMP values were 1.97 +/- 0.63 SD, 3.30 +/- 1.47 SD, and 3.49 +/- 1.47 SD (nmols/mg of protein). Our data support the hypothesis of a role for cGMP and PDE in the progression of OSCC.
