Comprehensive analysis of the TNM stage of the lung cancers, showed that TNM2 tumours had higher SIPA1 transcript levels than stage TNM1 tumours, and SIPA1 transcript levels in TNM2-3-4 stage was comprehensively higher than in the TNM1 tumours, but the difference was not statistically significant (Figure 1B). This evidence concerns the gene SIPA1 and lung carcinoma.
