To establish a more comprehensive picture of aberrant La protein expression in lung cancer, we analyzed by immunohistochemistry the La protein expression in two lung cancer tissue microarrays consisting of (A) 51 squamous cell carcinoma (SCC) along with 50 normal cancer adjacent tissues samples (TMA: BC04118) and (B) 49 adenocarcinoma along with 48 normal cancer adjacent tissues (TMA: LC1002). This evidence concerns the gene SSB and lung carcinoma.
