New molecular approaches to lung cancer: biological and clinical implications of P53, P16 and K-RAS studies.
The most common genetic changes associated with lung cancer involve abnormalities of the genes that regulate the cell cycle. Molecular networking of P53 and P16 tumor suppressor genes and K-RAS oncogene exerts a crucial impact on cell cycle regulation and appears to be of major clinical significance for lung cancer evaluation. The present review article summarizes evaluations of P53, P16 and K-RAS in lung cancer with particular focus on biological and clinical implications, as well as on new molecular approaches to the study of these genes: P53 by yeast functional assay, P16 by methylation specific PCR (MSP) and K-RAS by enriched PCR technique.
