Bacterial cupredoxin azurin as an inducer of apoptosis and regression in human breast cancer
(2004)Azurin, a copper-containing redox protein released by the pathogenic bacterium Pseudomonas aeruginosa, is highly cytotoxic to the human breast cancer cell line MCF-7, but is less cytotoxic toward p53-negative (MDA-MB-157) ...

Black cohosh (Cimicifuga racemosa L.) protects against menadione-induced DNA damage through scavenging of reactive oxygen species: Bioassay-directed isolation and characterization of active principles
(2002)The roots/rhizomes of Cimicifuga racemosa L. (Nutt.) (black cohosh) have traditionally been used to treat menopausal symptoms through an unknown mechanism of action. In an effort to determine if black cohosh had additional ...

Chemopreventive effects of soy protein and purified soy isoflavones on DMBA-induced mammary tumors in female Sprague-Dawley rats
(2001)There are conflicting reports on the effect of soy and its components on mammary carcinogenesis in adult female rats, mainly because of different rodent models that are used in chemoprevention studies. The present study ...

Computer-aided detection of breast cancer nuclei
(1997)A computer-aided detection system for tissue cell nuclei in histological sections is introduced and validated as part of the Biopsy Analysis Support System (BASS). Cell nuclei are selectively stained with monoclonal ...

Article
Identification of the polycomb group protein SU(Z)12 as a potential molecular target for human cancer therapy
(2003)We have previously identified SU(Z)12 as an E2F target gene. Because many E2F target genes encode proteins that are critical for the control of cell proliferation, we have further characterized the regulation and expression ...

Inhibition of N-methyl-N-nitrosourea-induced mammary tumors in rats by the soybean isoflavones
(1996)Soy-based diets, rich in the isoflavones genistein and daidzein, are thought to protect against breast and prostate cancer. Soy-based diets, rich in the isoflavones genistein and daidzein, are thought to protect against ...

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

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 ...

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

Article
The soy isoflavone daidzein improves the capacity of tamoxifen to prevent mammary tumours
(2005)The aim of this study was to determine how the efficacy of tamoxifen is affected when combined with soy isoflavones. To address this, female Sprague-Dawley rats were placed on diets supplemented with tamoxifen, genistein, ...

Soy protein isolate prevents chemically-induced rat mammary tumors
(2002)purified daidzein at 200 mg/kg diet

Article
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, ...

Synthesis, structural characterization and in vitro inhibitory studies against human breast cancer of the bis-(2,6-di-tert-butylphenol)tin(iv) dichloride and its complexes
(2012)Four new organotin(iv) complexes of bis-(2,6-di-tert-butylphenol)tin(iv) dichloride [(tert-Bu-)2(HO-Ph)]2SnCl2 (1) with the heterocyclic thioamides 2-mercapto-pyrimidine (PMTH), 2-mercapto-4-methyl- pyrimidine (MPMTH), ...

Targeting IL13Ralpha2 activates STAT6-TP63 pathway to suppress breast cancer lung metastasis
(2015)Introduction: Basal-like breast cancer (BLBC) is an aggressive subtype often characterized by distant metastasis, poor patient prognosis, and limited treatment options. Therefore, the discovery of alternative targets to ...

Vasodilator-Stimulated Phosphoprotein (VASP) depletion from breast cancer MDA-MB-231 cells inhibits tumor spheroid invasion through downregulation of Migfilin, β-catenin and urokinase-plasminogen activator (uPA)
(2017)A hallmark of cancer cells is their ability to invade surrounding tissues and form metastases. Cell-extracellular matrix (ECM)-adhesion proteins are crucial in metastasis, connecting tumor ECM with actin cytoskeleton thus ...
