SNHG9 was upregulated in NSCLC and associated with DDP-resistance and poor prognosis of NSCLC patients. A. TCGA data analysis showed the expression level of SNHG9 was higher in 553 human NSCLC tissues compared with 59 normal lung tissues. B. RT-qPCR showed the expression level of SNHG9 was higher in 50 local NSCLC tissues compared with adjacent normal lung tissues. C. The expression level of SNHG9 in DDP sensitive (CS) were much lower than that in DDP resistant (CT) NSCLC tissues. D. Kaplan-Meier curves showed the different OS rates in high SNHG9 group and low SNHG9 group NSCLC patients. E. RT-qPCR showed the expression level of SNHG9 in BEAS-2B, SK-MES-1, H460, A549, A549/DDP, H1299 and H1299/DDP cells. GAPDH was detected as control for RT-qPCR. *P<0.05; **P<0.01.
