Initially, we performed a statistical analysis to examine the relationship between the clinicopathological factors and the expression level of LINC01234. As a result, we found differentiation of GC was associated with LINC01234 expression, that means the lower the LINC01234 expression is, the more the possibility for poor differentiation of GC tissues is (P < .05, Table 1). The gene discussed is LINC01234; the disease is gastric cancer.
