GAS5 and neoplasm: According to GSE29079 dataset, the samples were divided into the neoplasm and benign groups, T-test analysis showed that 5 lncRNAs (AC005261.1 p = 2.16 × 10− 13, AC004542.2 p = 6.40 × 10− 17, ZFAS1 p = 1.06 × 10− 6, EBLN3P p = 8.09 × 10− 8, GAS5 p = 0.014) had been up-regulated in the tumor samples, while other 4 lncRNAs were not significant (Fig. 3).
