Figure 3.ZFAS1 is suitable for biomarker testing and may serve as a novel biomarker for GC. (A) The expression level of lncRNA ZFAS1 remained stable when incubated at room temperature for 6h and at 4°C for 12h. ZFAS1 was stable when stored at -80°C. (B) ZFAS1 remained relatively stable when treated with freeze-thaw cycles. (C) The ROC curve analysis for the diagnostic value of lncRNA ZFAS1 in GC (AUC = 0.727, sensitivity: 0.766; specificity: 0.639).
