GSN and cancer: In many cancers, GSN expression was positively linked to the CAFs infiltration level, with GSN expression significantly linked to the degree of CAFs infiltration in BLCA (r = 0.486), BRCA (r = 0.463), COAD (r = 0.467), DLBC (r = 0.542), PCPG (r = 0.551), PRAD (r = 0.815), STAD (r = 0.586), TGCT (r = 0.517), THCA (r = 0.520), and THYM (r = 0.742) (Figure 11B).
