KNTC1 and cholangiocarcinoma: For example, distinct peptide mass fingerprints (PMFs) were identified for early versus late recurrence in cholangiocarcinoma (CCA), where peptides such as KNTC1, DCLK1, ALG10, ATR, and BLM were associated with early recurrence, while SERPINA1, TGFB2, and SERPING1 were implicated in late recurrence [53].
