Defining the role of solid stress and matrix stiffness in cancer cell proliferation and metastasis
(2018)Solid tumors are characterized by an abnormal stroma that contributes to the development of biomechanical abnormalities in the tumor microenvironment. In particular, these abnormalities include an increase in matrix stiffness ...

Hyaluronan-Derived Swelling of Solid Tumors, the Contribution of Collagen and Cancer Cells, and Implications for Cancer Therapy
(2016)Despite the important role that mechanical forces play in tumor growth and therapy, the contribution of swelling to tumor mechanopathology remains unexplored. Tumors rich in hyaluronan exhibit a highly negative fixed charge ...

Article
Intelligent drug delivery systems for the treatment of solid tumors
(2016)The rationale for the use of nanoparticle formulations to treat cancer is based on the ability of these particles to facilitate selective delivery of drugs to the tumor site, reducing adverse effects and improving therapeutic ...

Article
Multiscale biphasic modelling of peritumoural collagen microstructure: The effect of tumour growth on permeability and fluid flow
(2017)We present an in-silico model of avascular poroelastic tumour growth coupled with a multiscale biphasic description of the tumour–host environment. The model is specified to in-vitro data, facilitating biophysically realistic ...

Article
Multiscale modelling of solid tumour growth: the effect of collagen micromechanics
(2016)Here we introduce a model of solid tumour growth coupled with a multiscale biomechanical description of the tumour microenvironment, which facilitates the explicit simulation of fibre–fibre and tumour–fibre interactions. ...

Article
Multistage nanoparticle delivery system for deep penetration into tumor tissue
(2011)Current Food and Drug Administration-approved cancer nanotherapeutics, which passively accumulate around leaky regions of the tumor vasculature because of an enhanced permeation and retention (EPR) effect, have provided ...
-
Article
Multistage nanoparticles for improved delivery into tumor tissue
(2012)The enhanced permeability and retention (EPR) effect has been a key rationale for the development of nanoscale carriers to solid tumors. As a consequence of EPR, nanotherapeutics are expected to improve drug and detection ...

Article
Pirfenidone normalizes the tumor microenvironment to improve chemotherapy
(2017)Normalization of the tumor microenvironment by selectively targeting components of the tumor extracellular matrix has been recently proposed to have the potential to decompress tumor blood vessels, increase vessel perfusion ...

Article
Reengineering the Tumor Vasculature: Improving Drug Delivery and Efficacy
(2018)[Figure presented] A solid tumor is like an aberrant organ – comprised of cancer cells and a variety of host cells embedded in an extracellular matrix – nourished by blood vessels and drained by lymphatic vessels. In its ...

Article
Remodeling components of the tumor microenvironment to enhance cancer therapy
(2015)Solid tumor pathophysiology is characterized by an abnormal microenvironment that guides tumor progression and poses barriers to the efficacy of cancer therapies. Most common among tumor types are abnormalities in the ...

Article
Remodeling of extracellular matrix due to solid stress accumulation during tumor growth
(2015)Solid stresses emerge as the expanding tumor displaces and deforms the surrounding normal tissue, and also as a result of intratumoral component interplay. Among other things, solid stresses are known to induce extensive ...

Article
Role of constitutive behavior and tumor-host mechanical interactions in the state of stress and growth of solid tumors
(2014)Mechanical forces play a crucial role in tumor patho-physiology. Compression of cancer cells inhibits their proliferation rate, induces apoptosis and enhances their invasive and metastatic potential. Additionally, compression ...

Article
The role of mechanical forces in tumor growth and therapy
(2014)Tumors generate physical forces during growth and progression. These physical forces are able to compress blood and lymphatic vessels, reducing perfusion rates and creating hypoxia. When exerted directly on cancer cells, ...

Article
Role of TGFβ in regulation of the tumor microenvironment and drug delivery (review)
(2015)Deregulation of cell signaling homeostasis is a predominant feature of cancer initiation and progression. Transforming growth factor β (TGFβ) is a pleiotropic cytokine, which regulates numerous biological processes of ...

Article
Role of vascular normalization in benefit from metronomic chemotherapy
(2017)Metronomic dosing of chemotherapy - defined as frequent administration at lower doses - has been shown to be more efficacious than maximum tolerated dose treatment in preclinical studies, and is currently being tested in ...
-
Article
The Solid Mechanics of Cancer and Strategies for Improved Therapy
(2017)Tumor progression and response to treatment is determined in large part by the generation of mechanical stresses that stem from both the solid and the fluid phase of the tumor. Furthermore, elevated solid stress levels can ...
-
Article
Targeting Inflammation to Improve Tumor Drug Delivery
(2017)Inefficient delivery of drugs is a main cause of chemotherapy failure in hypoperfused tumors. To enhance perfusion and drug delivery in these tumors, two strategies have been developed: vascular normalization, aiming at ...

Article
A Validated Multiscale In-Silico Model for Mechano-sensitive Tumour Angiogenesis and Growth
(2017)Vascularisation is a key feature of cancer growth, invasion and metastasis. To better understand the governing biophysical processes and their relative importance, it is instructive to develop physiologically representative ...
