Abstract:
Primary lung cancer specimens of the non-small cell (NSC) types were examined for expression of the c-jun gene at the protein level by immunocytochemistry using the polyclonal antibody c-jun 890. The results obtained revealed that the c-jun p39 protein was expressed in 82% (18/22) of squamous cell carcinomas, 77% (10/15) of adenocarcinomas and 40% (2/5) of large cell anaplastic carcinomas, but no staining was seen in the non-cancer cases. Positive immunostaining was also seen in 16.7% (3/18) of the nonneoplastic bronchial cells of positively stained squamous cell carcinomas and in 40% (4/10) of adenocarcinomas. We suggest that elevated expression df c-jun p39 protein which was seen in a total of 75% (30/40) of the NSCLC, plays a role in lung cancer.

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.
