Fig. 2. MIR99AHG is a potential tumor suppressor in LUAD.
a MIR99AHG expression was detected by RNA chromogenic in situ hybridization (CISH) on a TMA cohort containing 74 paired LUAD tissues and adjacent normal tissues. Representative images of nontumor and tumor tissues are shown. MIR99AHG was downregulated in tumor tissues (P = 0.006). b–d MIR99AHG expression was downregulated in higer T stage (b), N stage (c) or TNM stage (d) in the TMA cohort. e Kaplan–Meier analysis of the overall survival in the TMA cohort based on MIR99AHG (HR = 0.334, P = 0.001). f Univariate (upper panel) and multivaraite (lower panel) analyses of overall survival in the TMA cohort by Cox regression analysis. g, h Kaplan–Meier analysis of the overall (g HR = 0.655, P = 0.004) and disease-free (h, HR = 0.713, P = 0.023) survival in the TMA cohort based on MIR99AHG. A two-tailed Student’s t-test was used for statistical analysis. *P < 0.05, **P < 0.01, ***P < 0.001. Error bars, SEM.
