In Mel-PD1-B, 16 peptides (18%) displayed significantly differential signals for response (two-sided two sample t-test, p<0.05, FDR=25%) whereas NSCLC-PD1, 18 peptides (19%) were significantly differently phosphorylated in responders compared with non-responders (two-sided two sample t-test, p<0.05, FDR=24%). The gene discussed is PDCD1; the disease is non-small cell lung carcinoma.
