NID1 and neoplasm: Interestingly, the same research group in an independent study (with an independent panel of patients and using a different peptide quantification approach) discovered among others elevated levels of nidogen-1 (NID1) and serpin H1 (SERPINH1) along with proteins of the aminoacyl-tRNA biosynthesis pathway (IARS, KARS, WARS, and YARS) when they examined tumor interstitial fluids (TIF) in comparison with fluids from adjacent noncancerous (NIF) tissues.
