The results revealed high expression of STC2 in the majority of tumors, such as COAD, ESCA, GBM, HNSC, KIRC, LGG, OV, READ, UCEC, UCS and low expression in LAML, SKCM, indicating the significance of STC2 as a crucial biomarker for pan-cancer (Figure 8A). The gene discussed is STC2; the disease is cancer.
