NFKB1 and neoplasm: The data revealed the presence of nuclear p-NF-κB p65 in NB cells in TME-rich (>10% TME cells) tumours (average 30.12 ± 3.3%) compared with TME-poor (< 5% TME cells) tumours (average 3.25 ± 1.2%) or TME intermediate (TME cells between 9 and 6%) tumours (average 7.5 ± 2.6%) (Fig. 6b, c).
