Biomarkers can be used for the screening and clinical diagnosis of cancer,and peptidomics approach has been proven successful in the research of biomarkers.To develop better peptidomic technologies for fast,accurate,and reliable detection of peptides biomarkers for lung cancer,we have improved the procedures of blood collection to minimize the degradation of the blood proteins and optimize the extraction of peptidome peptides from plasma samples based on acetonitrile precipitation associated with size exclusion chromatography(SEC).Studies show that squamous cell carcinomas are found to express CAGEl,SPAT9 and TEX28 genes at significantly higher rates,and the results suggest that as tumors progress,the level of CAGEl,SPAT9 and TEX28 genes are likely to increase and lead to immunization.This suggests a potentially important therapeutic method for cancer testis-based cancer vaccines.

Studies show that squamous cell carcinomas are found to express CAGE1, SPAT9 and TEX28 genes at significantly higher rates, and the results suggest that as tumors progress, the level of CAGE1, SPAT9 and TEX28 genes are likely to increase and lead to immunization.
