PTEN and non-small cell lung carcinoma: We found that 58% of cases with lower PTEN expression (n = 22) were in the high EHMT2 expression group (n = 38), whereas 72% of cases with higher PTEN expression (n = 48) were in the low EHMT2 expression group (n = 67), indicating that EHMT2 expression was negatively correlated with PTEN expression in NSCLC tissues (P < 0.05, Fig. 6b).
