Prognose analyze of FGD5-AS1 in patients’ tissue. a QRT-PCR for FGD5-AS1 in 30 gastric cancer tissue cDNA chips comparing expression level in para-cancer tissue and cancer tissue. (Wilcoxon paired test was used to test the difference between paired samples because the difference value doesn’t obey normal distribution. * = significant, * P < 0.05; **, P < 0.01,***P < 0.005; **** < 0.001, Student t test). b &c&d&e According to the mean value of FGD5-AS1(presented by 2^-ΔΔ, Mean value: 10.81); patients were divided into two groups: high FGD5-AS1 expression and low FGD5- AS1 expression group. The expression level of FGD5-AS1 shows remarkably relation with anatomic stage/pronostic groups stages. Meanwhile comparing T1–2 vs T3–4, N0 vs N1–3, M0 vs M1 we can clearly summarize that the high level of FGD5-AS1 correlates with serious TMN stage. (* = significant,* P < 0.05; **, P < 0.01***, p < 0.005;****, p < 0.001; Student t test); f) Kaplan-Meier survival analysis of 875 gastric cancer patients downloaded from the TCGA database for the expression of FGD5-AS1 (Log Rank; p = 0.00045). The median expression of FGD5-AS1 was regarded as a cut off point. The red line represented the high expression group and the blank line represented the low expression group
