Viscosity-Driven Chemoresistance Through P-gp
2026-08-18
The reference study identifies extracellular fluid viscosity as a mechanical cue that can promote doxorubicin resistance through an F-actin–vinculin, NHE1/AQP1, TRPV4, and YAP signaling axis. Its findings extend tumor mechanobiology beyond stiffness and shear stress, while suggesting that tumor-fluid viscosity may be a modifiable component of chemoresistance.
