Aim:
Cyclooxygenase-2 is a key enzyme in the conversion of arachidonic acid to prostaglandins, and has critical role in the progression of several malignancies, including oral squamous cell carcinoma.
Methods:
We designed a case-control study to evaluate the susceptibility of the functional -765G>C genetic variation in oral squamous cell carcinoma patients. Polymerase chain reaction-based restriction fragment length polymorphism analysis was used to determine the polymorphism in oral squamous cell carcinoma (n = 150) patients and healthy controls (n = 150).
Results:
The genotype frequencies of cyclooxygenase-2 765G>G, 765G>C, and 765C>C were 73.3%, 18.66%, and 8.0% in the cancer patients, and 94.66%, 4% and 1.3% in the controls, respectively. The cyclooxygenase-2 GC and CC genotypes were significantly associated (P = 0.0003 and P = 0.01, respectively) with oral squamous cell carcinoma patients, when compared to the controls. The 765G>C genotypes were statistically significant, with habitual tobacco chewing and alcohol consumption + smoking (P = 0.05).
Conclusions:
This study highlights the genetic variant that might play a role in mediating susceptibility to oral squamous cell carcinoma in this population.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
