Figure 2E showed that both APOD and PROC were expressed at lower levels in GC patients harboring ARID1AMut (n = 84) compared to those with wild-type ARID1A (n = 282). The qRT-PCR data further confirmed that the expression levels of APOD and PROC were significantly lower in the ARID1AMut GC cell line SNU-216 compared to the ARID1AWT GC cell line HGC-27 (p < 0.01) (Figure 2F). The gene discussed is APOD; the disease is gastric cancer.
