c-Fos/ c-Jun transcription factors in non-small cell lung carcinoma

During lung carcinoma development, progression and metastasis, a variety of gross (chromosome) and specific (gene) genomic alterations are detected in dysplastic, neoplastic, and progressively malignant transformed epithelia as early or late genetic events. Oncogenes' overactivation combined with suppressor genes silence are crucial genetic events in malignant and pre-malignant epithelia. Especially, deregulation of crucial signalling transduction pathways that interact with strong transcription factors - such as c-Fos and c-Jun - leads to an aberrant expression of other critical genes responsible for cell homeostasis. Upregulation of c-Fos and c-Jun leading to other oncogenes overactivation seems to be correlated with aggressive biological behaviour in non-small cell lung carcinomas (NSCLCs). In the current special molecular article we explored the role of c-Fos/c-Jun complex deregulation in NSCLC based on their interactions with other genes that demonstrate modified expression profiles.
