TNFRSF1A and melanoma: The upregulation of TNFR1 mRNA expression in both melanoma cell lines correlated closely to the protein levels in the seed extracts, especially to the 36.7 kDa (r = 0.99, p < 0.001) and 20 kDa (r = 0.97, p < 0.001) proteins, whilst there were weak correlations with IAM-MCo-3, MCo-3 and MCoTI-I peptides (Figure 8A,B).
