ABSTRACT
BACKGROUND:
Transcriptional factors of the CREB(cAMP Response Element Binding Protein) are involved in the regulation of gene expression in response to a variety of signaling pathways. Proteins produced by the CREB genes play key roles in many physiological processes, including memory and long term potentiation. The retinoic acid receptor (RAR) axis mediates epithelial cell differentiation and proliferation in many tissues including the lung. MATERIAL ANDMETHOD:
The RAR and CREB expression levels were examined in 60 adenocarcinomas and 60 squamous cell carcinomas of the lung using immunohistochemical staining.RESULTS:
1)RAR protein expression was found in 58.3%(35/60) of adenocarcinomas and 36.7%(22/60) of squamous cell carcinomas(P0.05). 4)CREB expression was found in 61.7%(37/60) of adenocarcinomas and 40%(24/60) of squamous cell carcinomas(P0.05). 7)RAR and CREB expression was found in 68.5% of lung cancers, and there was a significant correlation between them(P<0.05).CONCLUSION:
RAR and CREB expression can be used to indirectly determine the malignant potentiality of a cell.
