TERT and head and neck squamous cell carcinoma: Using CIBERSORTx to deconvolute the relative proportion of cells in the tumor microenvironment (Table S4) (https://dice-database.org/genes/TERT) (72) and by interrogating single-cell data set of an HNSCC cohort (GSE103322) (Fig. S8), we found little if any evidence for TERT expression in B cells arguing that most TERT expression in HNSCC tissues may be contributed predominantly or solely by tumor cells.
