The heatmap of the 13 IRLPs showed that a score of 1 in AC107021.2|LINC02097, NR2F2-AS1|PICART1, AC010207.1|LINC01644, LINC01018|AP004609.1, LINC02610|BANCR, LSAMP-AS1|LINC01775, and LIFR-AS1|AC012313.5 was more distributed in the high-risk group, indicating their harmful roles in GC prognosis, while the remaining IRLPs showed the reverse trend (Figure 2C). Here, LSAMP-AS1 is linked to gastric cancer.
