IL17A and thyroid gland carcinoma: Interestingly, we identified some biological processes related to the TME in GO and KEGG enrichment analyses, such as response to fibroblast growth factor, extracellular matrix organization, collagen-containing extracellular matrix, endocytic vesicle lumen, signaling receptor activator activity, extracellular matrix structural constituent, growth factor activity, cytokine activity, cytokine-cytokine receptor interaction and the IL-17 signaling pathway, thus suggesting that our prognostic model may be closely related to the TME of thyroid cancer.
