To investigate whether FEZF1-AS1 could regulate cell-cycle, Additional file 3: Figure S2A illustrates plots from gene set enrichment analysis (GSEA) using gastric cancer patient gene profiling data (GSE53137) showing that gene set differences in FEZF1-AS1 high vs. low patients indicated that FEZF1-AS1 regulates gene sets mainly associated with cell cycle progression. Here, FEZF1 is linked to gastric cancer.
