Mechanochemical interactions in cancer cells: The role of substrate stiffness in cell behavior and drug response
Sayed Reza Ramezani, Afsaneh Mojra, Mohammad Tafazzoli-Shadpour
TL;DR
This study explores how the stiffness of the environment affects prostate cancer cell behavior and drug response, finding that softer substrates improve drug effectiveness.
Contribution
The study introduces a novel approach to evaluate the combined effects of substrate stiffness and drug treatments on prostate cancer cells with different metastatic potentials.
Findings
Cells on soft substrates showed a 40–60% increase in cell death compared to 20–30% on stiff substrates.
Drug treatments altered cell mechanics, with Docetaxel reducing elastic modulus and Bicalutamide increasing it.
Soft substrates correlated with lower phalloidin content in cancer cells compared to stiff substrates.
Abstract
Cancer cells adhere to the extracellular matrix, where they sense and respond to variations in substrate stiffness, influencing their proliferation and invasive potential. Numerous studies have examined the biological activities of cells in relation to mechanical forces; however, research addressing the combined effects of mechanical and chemical interactions on cancer cell behavior across different metastatic stages remains limited. Moreover, the influence of chemotherapeutic drugs in the context of specific cellular characteristics remains underexplored. Therefore, in this study, synthetic polyacrylamide gels with varying elastic moduli were utilized to effectively mimic the diversity of host tissue environments for prostate cancer cells. Additionally, cellular behavior of prostate cancer cells with differing metastatic potential—low (LNCaP), medium (DU145), and high (PC3)—was…
