We further analyzed the relationship among DIRAS3 protein expression and age, gender, pathological grade, pathological differentiation, TNM stage, and lymph node metastasis (LNM) of NSCLC patients, and as illustrated in Table 1, we uncovered that DIRAS3 protein expression was associated with pathological differentiation, TNM stage, and LNM. This evidence concerns the gene DIRAS3 and non-small cell lung carcinoma.
