Among them, several pathways, which were highly related to the tumorigenesis and development of cancers, were enriched, such as the P53 signaling pathway, Jak-stat signaling pathway, etc. In addition, in the low-level SLC7A11 group, multiple immune-related pathways were identified, which may be the reason for the better prognosis in patients with low SLC7A11 expression level. Here, SLC7A11 is linked to cancer.
