On the other hand, the tumor margin was characterized by a higher abundance of TATA binding protein (RUVBL1), PKM isoform d, HNRPF protein (HNRPF), KRT19, serpin B1 protein (SERPINB1), inorganic pyrophosphatase (PPA1), N-acetyl-D-glucosamine kinase isoform 1 (NAGK), F-actin-capping protein (CAPZA1), alpha SNAP (NAPA), microtubule-associated protein RP/EB (MAPRE1), cathepsin D (CTSD), peroxiredoxin 4 (PRDX4), cyclophilin B (PPIB, two proteoforms), and ARHGDIB. Here, NAGK is linked to neoplasm.
