Moreover, SELPLG has been studied in several kinds of cancers as potential diagnostic or prognostic biomarkers, such as colorectal cancer (CRC) [17], head and neck squamous cell carcinoma (HNSCC) [18], anaplastic large T-cell lymphoma (ALCL) [19], uveal melanoma [20], and so on. Here, SELPLG is linked to head and neck squamous cell carcinoma.
