a strong trendgold
The biliary-like ampullary group, which showed a strong trend for shorter survival, showed increased expression of activation-specific markers in several kinase signaling pathways, including the PI3K-AKT (P-AKT Ser473, P-GSK3 Ser21, P-P70S6K T389, P-mTOR S2448, and P-FOXO3a), RAS-RAF-MEK-ERK (P-MAPK, P-MEK), and JAK-STAT (P-STAT3 S727) ( Table S2 ).
