FN1 and neoplasm: Analogous to coordinated high FAP and FN1 expression levels in many cancers [9], in silico analysis of the Human Protein Atlas IHC database demonstrated elevated protein expression levels of both FAP and FN1 in all TC subtypes with the highest FN1 and the 6th highest FAP expression levels in ATC when compared to other cancer types (Fig. 1A), while the expression of FAP and FN1 was low in adjacent non-tumor tissues (Fig. 1B).
