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

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 ...

Caspase-independent pathways of programmed cell death: The unraveling of new targets of cancer therapy?
(2009)In the past few years, accumulating evidence in the literature supports the existence of pathways of caspase-independent programmed cell death (CI-PCD). These pathways are likely to be acting as 'death backup systems' that ...

Computer-aided classification of breast cancer nuclei
(1996)Breast cancer is the most common malignancy affecting the female population in industrialized countries. Prognostic factors, such as steroid receptors visualized in biopsy slides, provide critical information to oncologists ...

Article
Content-based retrieval of breast cancer biopsy slides
(2000)The Biopsy Analysis Support System (BASS), previously used for image analysis of immunohistochemically stained sections of breast carcinoma, has been extended to include indexing and content-based retrieval of biopsy slide ...

Delivering nanomedicine to solid tumors
(2010)Recent advances in nanotechnology have offered new hope for cancer detection, prevention, and treatment. While the enhanced permeability and retention effect has served as a key rationale for using nanoparticles to treat ...

Distribution of epidermal growth factor receptors in normal and neoplastic mammary tissues
(1995)Epidermal growth factor (EGF) is considered to be mitogenic for proliferation of mammary glands in animals. The action of EGF is mediated by specific EGF receptors (EGF-R). In the present study, we investigated distribution ...

The effect of the phytoestrogens genistein, daidzein, and equol on the growth of tamoxifen-resistant T47D/PKCα
(2007)Soy supplements are often consumed by women for alleviating menopausal symptoms or for the perceived protective effects against breast cancer. More concerning is the concurrent consumption of soy isoflavones with tamoxifen ...

Article
Evaluation of estrogenic activity of plant extracts for the potential treatment of menopausal symptoms
(2001)Eight botanical preparations that are commonly used for the treatment of menopausal symptoms were tested for estrogenic activity. Methanol extracts of red clover (Trifolium pratense L.), chasteberry (Vitex agnus-castus ...

Article
Genistein induces apoptosis and topoisomerase II-mediated DNA breakage in colon cancer cells
(2000)The present study was undertaken to determine if (a) genistein induces topo II-mediated DNA damage in HT-29 colon cancer cells

Article
Genistein induces maturation of cultured human breast cancer cells and prevents tumor growth in nude mice
(1998)Results of recent studies in animal models of mammary carcinogenesis showed that the soybean isoflavone genistein is a chemopreventive agent. The objective of the present study was to determine whether soybean isoflavones ...

Article
Identification of Ras suppressor-1 (RSU-1) as a potential breast cancer metastasis biomarker using a three-dimensional in vitro approach
(2017)Breast cancer (BC) is the most common malignant disease in women, with most patients dying from metastasis to distant organs, making discovery of novel metastasis biomarkers and therapeutic targets imperative. Extracellular ...

Article
Improved detection of breast cancer nuclei using modular neural networks
(2000)A modular neural network-based approach to detect and classify breast cancer nuclei stained for steroid receptors in hispathological sections is evaluated. The system named biopsy analysis support system (BASS) is designed ...

Article
Induction of human adenocarcinoma cell differentiation by the phytoestrogen genistein is independent of its antiestrogenic function
(1997)The objective of the present study was to determine if genistein can induce human breast adenocarcinoma cell maturation. To gain understanding on its mechanism of action, we used estrogen receptor-positive (ER+) MCF-7, and ...

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 ...

Prevention of preneoplastic mammary lesion development by a novel vitamin D analogue, 1α-hydroxyvitamin D5
(1997)Background: The form of vitamin D (vitamin D3) in fortified milk and the provitamin D produced by the body undergo metabolic activation to a biologically active form, 1α,25-dihydroxyvitamin D3 [1α,25(OH)2D3]. This compound ...

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 ...

Rotenoids mediate potent cancer chemopreventive activity through transcriptional regulation of ornithine decarboxylasetissue plasminogen activator-mediated thrombolysis
(1995)For the discovery of new cancer chemopreventive agents, we have studied the potential of plant extracts to inhibit phorbol ester-induced ornithine decarboxylase (ODC) activity in cell culture. Four active rotenoids were ...
