LINC00342 and gastric cancer: To explore the role of LINC00342 in GC, the expression of LINC00342 in GC tissues was evaluated by qRT-PCR and the results showed that LIC00342 was significantly upregulated in GC tissues (n = 30) compared with that in matched adjacent tissues (n = 30) (p < 0.01, Fig. 1a).
