From: LncRNA PLAC 2 downregulated miR-21 in non-small cell lung cancer and predicted survival
Low PLAC2 levels predicted poor survival. Among 70 NSCLC patients, non-metastasis (NM) was found in 17 cases, lymph node metastasis-only (LNM) was found in 38 cases and distant metastasis (DM) was found in 17 cases. Expression levels of PLAC2 were compared among groups by performing one-way ANOVA and Tukey test. It was found that expression levels of PLAC2 were significantly lower in DM group than in LNM and NM groups. In addition, expression levels of PLAC2 were also significantly lower in LNM than in NM groups (a), (*, p < 0.05). Survival analysis was performed using K-M method and log-rank test. It was observed that patients with low PLAC2 levels in NSCLC tissues had much worse survival (b)
