Targeting extracellular matrix stiffness and mechanotransducers to improve cancer therapy
Journal of Hematology & Oncology, 2022 Cancer microenvironment is critical for tumorigenesis and cancer progression. The extracellular matrix (ECM) interacts with tumor and stromal cells to promote cancer cells proliferation, migration, invasion, angiogenesis and immune evasion.

Arterial Stiffness and Cardiovascular Risk in Hypertension.
Circulation Research, 2021 Arterial stiffness, a leading marker of risk in hypertension, can be measured at material or structural levels, with the latter combining effects of the geometry and composition of the wall, including intramural organization.

Matrix Stiffness Contributes to Cancer Progression by Regulating Transcription Factors
Cancers, 2022 Simple Summary Matrix stiffness is recognized as a critical factor in cancer progression. Recent studies have shown that matrix stiffening is caused by the accumulation, contraction, and crosslinking of the extracellular matrix by cancer and stromal ...
