ImpactModerate impact

Participants suggest the research could influence future cancer therapies, reflecting a notable potential impact, although some statements are more anticipatory than conclusive.

Abstract in brief

PDAC is characterized by a fibrotic and stiff extracellular matrix, which complicates understanding its impact on tumor behavior and chemoresistance.
Patient-derived organoids show resistance to chemotherapy when grown in high-stiffness matrices that mimic the tumor environment, indicating the importance of the extracellular matrix's mechanical properties.
The study reveals that chemoresistance is linked to increased expression of drug efflux transporters influenced by interactions between the CD44 receptor and hyaluronan, and it can be reversed by switching to a low-stiffness matrix, suggesting a potential therapeutic target.
