Atomic Force Microscopy Probing of Cancer Cells and Tumor Microenvironment Components
(2016)Cancer cells have different characteristics from normal cells in terms of morphology, cell–cell interactions, cytoskeleton organization, cell growth rates, and cell-extracellular matrix interactions. Although the clarification ...

Article
Biphasic modeling of brain tumor biomechanics and response to radiation treatment
(2016)Biomechanical forces are central in tumor progression and response to treatment. This becomes more important in brain cancers where tumors are surrounded by tissues with different mechanical properties. Existing mathematical ...

Causes, consequences, and remedies for growth-induced solid stress in murine and human tumors
(2012)The presence of growth-induced solid stresses in tumors has been suspected for some time, but these stresses were largely estimated using mathematical models. Solid stresses can deform the surrounding tissues and compress ...

Article
Coevolution of solid stress and interstitial fluid pressure in tumors during progression: Implications for vascular collapse
(2013)The stress harbored by the solid phase of tumors is known as solid stress. Solid stress can be either applied externally by the surrounding normal tissue or induced by the tumor itself due to its growth. Fluid pressure is ...

Composition and histone substrates of polycomb repressive group complexes change during cellular differentiation
(2005)Changes in the substrate specificities of factors that irreversibly modify the histone components of chromatin are expected to have a profound effect on gene expression through epigenetics. Ezh2 is a histone-lysine ...

D-alpha-tocopheryl polyethylene glycol succinate (TPGS) induces cell cycle arrest and apoptosis selectively in Survivin-overexpressing breast cancer cells
(2014)d-alpha-tocopheryl polyethylene glycol succinate (TPGS) is a vitamin E derivative that has been intensively applied as a vehicle for drug delivery systems to enhance drug solubility and increase the oral bioavailability ...

Article
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 ...

Depletion of histone N-terminal-acetyltransferase Naa40 induces p53-independent apoptosis in colorectal cancer cells via the mitochondrial pathway
(2016)Protein N-terminal acetylation is an abundant post-translational modification in eukaryotes implicated in various fundamental cellular and biochemical processes. This modification is catalysed by evolutionarily conserved ...

Article
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
Identification of the factors responsible for the in vitro pro-oxidant and cytotoxic activities of the olive polyphenols oleuropein and hydroxytyrosol
(2013)The olive polyphenols oleuropein and hydroxytyrosol were reported recently to produce extracellular hydrogen peroxide (H2O2) under standard culture conditions. The precise factors responsible for this production and the ...

Induction of discrete apoptotic pathways by bromo-substituted indirubin derivatives in invasive breast cancer cells
(2012)Indirubin derivatives gained interest in recent years for their anticancer and antimetastatic properties. The objective of the present study was to evaluate and compare the anticancer properties of the two novel bromo-substituted ...

A metabolite of equine estrogens, 4-hydroxyequilenin, induces DNA damage and apoptosis in breast cancer cell lines
(2000)Estrogen replacement therapy has been correlated with an increased risk of developing breast or endometrial cancer. 4-Hydroxyequilenin (4-OHEN) is a catechol metabolite of equilenin which is a minor component of the estrogen ...

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
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
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 ...

Stable transfection of an estrogen receptor beta cDNA isoform into MDA-MB-231 breast cancer cells
(2003)We previously reported stable transfection of estrogen receptor alpha (ERα) into the ER-negative MDA-MB-231 cells (S30) as a tool to examine the mechanism of action of estrogen and antiestrogens [J. Natl. Cancer Inst. 84 ...

Stress-mediated progression of solid tumors: effect of mechanical stress on tissue oxygenation, cancer cell proliferation, and drug delivery
(2015)Oxygen supply plays a central role in cancer cell proliferation. While vascular density increases at the early stages of carcinogenesis, mechanical solid stresses developed during growth compress tumor blood vessels and, ...

Study on single crystal structure of the antimony(III) bromide complex with 3-methyl-2-mercaptobenzothiazole and biological activity of some antimony(III) bromide complexes with thioamides
(2012)Crystals of the [SbBr3(MMBZT)2] (1) complex (MMBZT = N-methyl-2- mercaptobenzothiazole) were grown from acetonitrile/methanol of the filtrate derived from the reaction between 3-methyl-2-mercaptobenzo thiazole (MMBZT) in ...
