Figure Lengend Snippet: Graphical summary of the possible mechanisms of USP1/ITGB5 axis in CP progression. USP1 deubiquitinates and stabilizes ITGB5, upregulates ITGB5 expression, and ITGB5 activated the PI3K/AKT pathway and subsequently activates PSCs, leading to pancreatic fibrotic injury in CP. Arrow: promotion; “tee” head: inhibition
