Angiotensin inhibition enhances drug delivery and potentiates chemotherapy by decompressing tumour blood vessels

Chauhan, V. P.; Martin, J. D.; Liu, H.; Lacorre, D. A.; Jain, S. R.; Kozin, S. V.; Stylianopoulos, T.; Mousa, A. S.; Han, X.; Adstamongkonkul, P.; Popovic, Z.; Huang, P.; Bawendi, M. G.; Boucher, Y.; Jain, R. K. (2013)

Cancer and stromal cells actively exert physical forces (solid stress) to compress tumour blood vessels, thus reducing vascular perfusion. Tumour interstitial matrix also contributes to solid stress, with hyaluronan ...

Multiscale modelling of solid tumour growth: the effect of collagen micromechanics

Wijeratne, P. A.; Vavourakis, V.; Hipwell, J. H.; Voutouri, C.; Papageorgis, P.; Stylianopoulos, T.; Evans, A.; Hawkes, D. J. (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. ...

Normalization of tumour blood vessels improves the delivery of nanomedicines in a size-dependent manner

Chauhan, V. P.; Stylianopoulos, T.; Martin, J. D.; PopoviÄ, Z.; Chen, O.; Kamoun, W. S.; Bawendi, M. G.; Fukumura, D.; Jain, R. K. (2012)

The blood vessels of cancerous tumours are leaky and poorly organized. This can increase the interstitial fluid pressure inside tumours and reduce blood supply to them, which impairs drug delivery. Anti-angiogenic ...

Pirfenidone normalizes the tumor microenvironment to improve chemotherapy

Polydorou, C.; Mpekris, F.; Papageorgis, P.; Voutouri, C.; Stylianopoulos, T. (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 ...

Remodeling of extracellular matrix due to solid stress accumulation during tumor growth

Pirentis, A. P.; Polydorou, C.; Papageorgis, P.; Voutouri, C.; Mpekris, F.; Stylianopoulos, T. (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 ...

Role of constitutive behavior and tumor-host mechanical interactions in the state of stress and growth of solid tumors

Voutouri, C.; Mpekris, F.; Papageorgis, P.; Odysseos, A. D.; Stylianopoulos, T. (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 ...

Sonic-hedgehog pathway inhibition normalizes desmoplastic tumor microenvironment to improve chemo- and nanotherapy

Mpekris, F.; Papageorgis, P.; Polydorou, C.; Voutouri, C.; Kalli, M.; Pirentis, A. P.; Stylianopoulos, T. (2017)

Targeting the rich extracellular matrix of desmoplastic tumors has been successfully shown to normalize collagen and hyaluronan levels and re-engineer intratumoral mechanical forces, improving tumor perfusion and chemotherapy. ...

A structural, kinetic model of soft tissue thermomechanics

Barocas, V. Η; Stylianopoulos, T.; Aksan, A. (2008)

A structure-based kinetic model was developed to predict the thermomechanical response of collagenous soft tissues. The collagen fibril was represented as an ensemble of molecular arrays with cross-links connecting the ...
