GAS5 and osteosarcoma: Then, using the univariate Cox regression analysis and Kaplan–Meier survival analysis, we identified 8 robust prognostic lncRNAs among the 352 m6A-related lncRNAs, with 5 lncRNAs (AL161729.1, EPB41L4A-AS1, SNHG7, GAS5, and SNHG6) were considered as risk factors and 3 lncRNAs (FGD5-AS1, PAXIP1-AS2, and AC004812.2) were protective factors for osteosarcoma patients (Figure 2B).
