LOPEZ-DURAN, M. et al. Application of molecular biology techniques in oral cancer. Av Odontoestomatol [online]. 2010, vol.26, n.4, pp.189-196. ISSN 2340-3152.

This article summarizes the main techniques in the area of molecular biology that are available for the investigation of oral cancer and precancer. They have been classified depending on the biological material we expect to analyze, which can be DNA, RNA or proteins. The explanation for each technique includes a brief description of its basics, as well as some advantages, drawbacks and current use of the technique. Our aim is to throw light on the applications of these techniques, soon indispensable for most studies, in the early diagnosis, prognosis and individualized treatment of oral carcinoma. The most useful techniques for this objective are nowadays: gel electrophoresis, hybridation, microarray technology, biochips, PCR (conventional, quantitative or reverse transcriptase), Southern, Northern and Western blot studies, DNA sequenciation, cloning, immunohistochemistry, ELISA and flow citrometry. Some techniques that deserve a special mention due to their greater usefulness in the area of oral cancer are microarray technology, biochips and PCR.
