TP53 and melanoma: In all melanomas, the C-terminally truncated p53β isoforms were the most highly detected p53 isoforms in the nucleus (median H-score: 40.81, IQR: 50.63), followed by TAp53 isoforms (median H-score: 32.50, IQR: 59.63, not significant), and the N-terminally truncated Δ40p53 isoforms (median H-score: 10.34, IQR: 25.68, p < 0.0001) and Δ133p53 isoforms (median H-score: 6.28, IQR: 13.15, p < 0.0001).
