dysregulated UCA1 was found in GC tissues and relates to worse prognosis. a The UCA1 level from two microarray datasets (GSE54129and GSE65801) was analyzed by student’s t-test. P < 0.05 was considered statistically significant. b The UCA1 level in 40 paired gastric adenocarcinoma and corresponding adjacent non-tumorous gastric tissue was detected by qPCR. Results were exhibited according to Lauren classification and analyzed by One-way ANOVA. **p < 0.01. c Representative images of in situ hybridization showing UCA1 expression within GC and control tissues. The relative density of UCA1 signal was quantified by Image J, and the significant was determined by student’s t-test. Scale bar, 100 μM. d The survival data containing 320 intestinal GC, 241 diffused GC and 32 mixed GC were analyzed by Kaplan-Meier analysis and p < 0.05 was considered statistically significant
